An untold story in biology: the historical continuity of evolutionary ideas of Muslim scholars from the 8th century to Darwin’s time

Textbooks on the history of biology and evolutionary thought do not mention the evolutionary ideas of Muslim scholars before Darwin’s time. This is part of a trend in the West to minimise the contributions of non-Western scientists to biology, human anatomy and evolutionary biology. Therefore, this paper focuses on the contributions of pre-Darwinian Muslim scholars to the history of evolutionary thought. Our review of texts from a wide range of historical times, and written in various languages, reveals that there were in fact several Muslim scholars who postulated evolutionary ideas, some with remarkable similarities to Darwin’s theory. These ideas included the adaptation and survival of the fittest, a specific origin of humans from apes/monkeys, the notion of evolutionary constraints, the occurrence of extinctions within taxa and hereditary variability. Moreover, while both the scientific community and the broader public generally base their knowledge on Western textbooks, several parts of the Muslim world have indicated an overall rejection of biological–including human–evolution. Therefore, to improve historical accuracy and create a better understanding of scientific history, the world’s diverse civilisations and their philosophies, this untold story should be widely disseminated to the scientific community and the general public.     

Comparing naturalized alien plants and recipient habitats across an east–west gradient in the Mediterranean Basin

Aim To investigate alien plant species invasion levels in different habitats and alien species traits by comparing the naturalized flora in different areas of the same biogeographical region. Location Spain, Italy, Greece and Cyprus. Methods Comparison of floristic composition, species traits and recipient habitats of naturalized alien neophytes across an east–west gradient comprising four countries in the European Mediterranean basin. Results A total of 782 naturalized neophytes were recorded; only 30 species were present in all four countries. Although floristic similarity is low, the four alien floras share the same patterns of growth form (mostly herbs), life cycle (mostly perennials) and life form (mostly therophytes, hemicryptophytes and phanerophytes). The majority of the recipient habitats were artificial. Wetlands were the natural habitats, with the highest numbers of naturalized species. Floristic similarity analyses revealed: (1) the highest floristic similarity between Italy and Spain, both of which were more similar to Greece than to Cyprus; (2) two groups of floristic similarity between habitat categories in each country (Greece–Cyprus and Italy–Spain); (3) a higher degree of homogenization in the plant assemblages in different habitats in Greece and Cyprus and a lower degree of homogenization in those in Italy and Spain; and (4) a higher degree of homogenization in artificial and natural fresh‐water habitats than in the other natural habitats. Main conclusions The floristic similarity of naturalized neophytes between the four countries is low, although the overall analysis indicates that the western group (Italy–Spain) is separated from the eastern group (Greece–Cyprus). Similar patterns emerged regarding the life‐history traits and recipient habitats. The artificial habitats and the natural wet habitats are those that are invaded most and display the greatest homogenization in all four countries. Coastal habitats display a lower degree of homogenization but a high frequency of aliens. Dry shrubs and rocky habitats display a lower degree of homogenization and a low frequency of aliens.     

Developments in stem cell research and therapeutic cloning: Islamic ethical positions, a review

Stem cell research is very promising. The use of human embryos has been confronted with objections based on ethical and religious positions. The recent production of reprogrammed adult (induced pluripotent) cells does not - in the opinion of scientists - reduce the need to continue human embryonic stem cell research. So the debate continues. Islam always encouraged scientific research, particularly research directed toward finding cures for human disease. Based on the expectation of potential benefits, Islamic teachings permit and support human embryonic stem cell research. The majority of Muslim scholars also support therapeutic cloning. This permissibility is conditional on the use of supernumerary early pre-embryos which are obtained during infertility treatment in vitro fertilization (IVF) clinics. The early pre-embryos are considered in Islamic jurisprudence as worthy of respect but do not have the full sanctity offered to the embryo after implantation in the uterus and especially after ensoulment. In this paper the Islamic positions regarding human embryonic stem cell research and therapeutic cloning are reviewed in some detail, whereas positions in other religious traditions are mentioned only briefly. The status of human embryonic stem cell research and therapeutic cloning in different countries, including the USA and especially in Muslim countries, is discussed.     

Chronological change of resource metabolism and decarbonization patterns in Pakistan: Perspectives from a typical developing country

With economic growth in many developing countries, not all are making similar progress with regard to material and environmental efficiencies. This study examines material use and CO₂ emission patterns and intensities from 1971 to 2015 in a typical developing country, Pakistan, and investigates national‐level and multi‐country‐level efficiency improvements using data envelopment analysis. The results are used to derive key policy insights for a sustainable economic transition with higher resource and carbon efficiencies. Results show that material intensity has reduced by 39.1% while CO₂ intensity has risen by 21.5% in the country. Pakistan, when compared with its top 10 export countries, was relatively more material and CO₂ intensive. National‐level efficiency was found to be low in most of the periods due to material/energy intensive agriculture and industries, low value‐added exports, etc. Insights from the national‐level efficiency analysis indicate that surging CO₂ intensities have started to decline since 2010 and the economy has greatly stabilized. Multi‐country analysis revealed that the efficiency gap between Pakistan and its developed export countries (such as the United Kingdom and France) has widened during the study period. Insights from the multi‐country analysis suggest that the economic growth and industrialization improves material and environmental efficiencies to some extent, yet these improvements are not equally distributed among all countries. As a way forward, integrated policies on sustainable resource consumption, carbon mitigation, and economic growth are necessary for accruing higher benefits from rising global trade and resource connectedness.     

A Comprehensive Material Flow Account for Lao PDR to Inform Environmental and Sustainability Policy

Modern environmental and sustainability policy that acknowledges the linkages between socioeconomic processes and environmental pressures and impacts, and designs policies to decouple economic activity from environmental pressures and impacts, requires a sophisticated and comprehensive knowledge base. The concept of industrial metabolism provides a sound conceptual base, and material flow accounting—including primary material inputs and outflows of waste and emissions—provides a well‐accepted operationalization. Studies presenting a comprehensive material flow account for a national economy are rare, especially for developing countries. Countries such as Lao People's Democratic Republic (Lao PDR or Laos) face dual objectives of improving the material standard of living of their people while managing natural resources sustainably and mitigating adverse environmental impacts from growing resource throughput. Our research fills a knowledge gap, presents a comprehensive account of material inputs and outflows of waste and emissions for the Lao PDR national economy, and applies the accounting approach for a low‐income economy in Asia. We present a material balance for the years 2000 and 2015. For this research, we used data from Lao PDR national statistics and the accounting guidelines of the European Statistical Office (Eurostat), which pioneered the use of material flow data as part of its official statistical reporting. We demonstrate the feasibility of the accounting approach and discuss the robustness of results using uncertainty analysis conducted with statistical approaches commonly used in the field of industrial ecology, including Gauss's law of error propagation and Monte Carlo simulation. We find that the fast‐changing scale and composition of Lao PDR material flows, waste, and emissions presents challenges to the existing policy capacity and will require investment into governance of changed patterns of material use, waste disposal, and emissions. We consider the data analysis sufficiently robust to inform such a change in policy direction.     

Reinterpreting Responsiveness for Health Systems Research in Low and Middle‐Income Countries

The ethical concept of responsiveness has largely been interpreted in the context of international clinical research. In light of the increasing conduct of externally funded health systems research (HSR) in low‐ and middle‐income countries (LMICs), this article examines how responsiveness might be understood for such research and how it can be applied. It contends that four features (amongst others) set HSR in LMICs apart from international clinical research: a focus on systems; being context‐driven; being policy‐driven; and being closely linked to development objectives. These features support reinterpreting responsiveness for HSR in LMICs as responsiveness to systems needs, where health system performance assessments can be relied upon to identify systems needs, and/or responsiveness to systems priorities, which entails aligning research with HSR priorities set through country‐owned processes involving national and sub‐national policymakers from host countries. Both concepts may be difficult to achieve in practice. Country ownership is not an established fact for many countries and alignment to their priorities may be meaningless without it. It is argued that more work is, therefore, needed to identify strategies for how the responsiveness requirement can be ethically fulfilled for HSR in LMICs under non‐ideal conditions such as where host countries have not set HSR priorities via country‐owned processes. Embeddedness is proposed as one approach that could be the focus of further development.     

Participatory forest monitoring: an assessment of the accuracy of simple cost–effective methods

International forest policies have recently increased the focus on involvement of local communities in forest monitoring and management as a strategy to improve biodiversity conservation efforts and local livelihood in developing countries. However, little is known about feasible methods, costs and accuracy of participatory monitoring schemes in developing countries. This paper examines the costs, accuracy and local reproducibility of three simple cost–effective methods for monitoring forest disturbance by local participants: (1) 20-trees method, (2) Bitterlich gauge method and (3) Disturbance Checklist transect. Using one of these methods the costs of monitoring forest habitats are only between US$ 0.04 and 0.12 ha⁻¹ annually, depending on the methods used, this is significantly cheaper than the costs of traditional scientific methods for biodiversity monitoring. Results indicate that local community members without former scientific training can collect accurate data on habitat loss and forest disturbance after only a few days of introduction to the methods, and thereby contribute with valuable information for natural resource management. The strengths and weaknesses of monitoring done, respectively, by local community members and educated biologists, respectfully, are discussed. It is suggested that these approaches should be seen as supplements to each other rather than substitutes. Finally, it is argued that monitoring schemes in developing countries can be sustained after donor funds have ceased only if the local communities play a central role and clear financially and/or socially incentives for members of the local community are incorporated.     

Agriculture and food from the Roman to the Islamic Period in the North-East of the Iberian peninsula: archaeobotanical studies in the city of Lleida (Catalonia, Spain)

The urban archaeological excavations carried out in the city of Lleida (Catalonia, Spain) have opened the way for an interdisciplinary project on the ancient landscape, agriculture and food. Here we present the results of the archaeobotanical study of seeds and fruits from this project, centred on the Roman and Islamic periods of the city, between the 2nd century B.C. and the 11th century A.D. During the whole of this period the cultivation and consumption of cereals was found. The most important cereals were hulled barley and naked wheat. This was already known from the later prehistoric era in the area and is similar to findings at other sites from the same period in the western Mediterranean. These cereals are accompanied by some leguminous crops and the presence of grapes and figs is very significant. The expansion of vine cultivation, together with a certain amount of tree growing was one of the basic contributions of the Roman world to proto-historical (Bronze- and Iron Age) agriculture in western Catalonia, as in other parts of Europe. In the Islamic period, there seems to have been an increase in the number of fruit tree species; however for taphonomical reasons this has to be confirmed by future investigations. Flax, already known in prehistoric times, and Gold-of-pleasure must be added to the finds. Also since the Roman period some other taxa, such as celery or fennel, might have been grown. During the time period considered in this paper, there was a wide range of plants grown and consumed. This clearly contrasts with everything known about earlier periods in western Catalonia, during which the only cultivated plants were cereals and flax.     

Women in developing countries and benefit sharing

The aim of this paper is to show that any process of benefit sharing that does not guarantee the representation and participation of women in the decision-making process, as well as in the distribution of benefits, contravenes a central demand of social justice. It is argued that women, particularly in developing countries, can be excluded from benefits derived from genetic research because of existing social structures that promote and maintain discrimination. The paper describes how the structural problem of gender-based inequity can impact on benefit sharing processes. At the same time, examples are given of poor women's ability to organise themselves and to achieve social benefits for entire communities. Relevant international guidelines (e.g. the Convention on Biodiversity) recognise the importance of women's contributions to the protection of biodiversity and thereby, implicitly, their right to a share of the benefits, but no mechanism is outlined on how to bring this about. The authors make a clear recommendation to ensure women's participation in benefit sharing negotiations by demanding seats at the negotiation table.     

Major Concerns in Developing Countries: Applications of the Precautionary Principle in Ecuador

Ecuador is a Latin American country with one of the biggest biodiversities. At the same time, social and environmental problems are also big. Poverty, political and social problems as well as questions like old transport systems, imported hazards from industrialized countries and lack of information and weak health care systems are the framework of this situation. The most common problems are the use of heavy metals in many activities without safety and health protection, a low technological oil production during two decades, intensive use of pesticides in agriculture, and some other chemical risks. A limited capacity to develop prevention strategies, reduced technical and scientific skills, and the absence of a reliable information and control system, lead to a weak response mechanism. The Precautionary Principle could help to stimulate prevention, protection and to have a new tool to improve the interest in environment and health problems. Reinforcing the presence of international organizations like WHO and ILO, establishing bridges among scientific organizations from developed and developing countries and introducing the Precautionary Principle in the legislation and daily practices of industry and agriculture could lead to an improvement in our environment and health.
