This paper tries to explain how individuals manage adaptive individual choice (i.e., the decision to acquire a fitter than
average behavior or idea rapidly and tractably) in cultural evolution, despite the fact that acquiring fitness information
is very difficult. I argue that the means of solving this problem suggested in the cultural evolution literature largely are
various types of decision rules employing representations of fitness correlated properties or states of affairs. I argue that
the problem of adaptive individual choice is best solved where some of these learning rule representations are socially transmitted
and some are biologically transmitted.

In a widely cited essay published in the journal Science (Aug. 2006), it was stated that in Germany a large majority of adults are convinced of evolution. Based on a new poll, I
document that this conclusion is questionable. In Sept. 2005, 60.9% of the German population accepted naturalistic evolution,
whereas 37.7% were creationists or adherents of intelligent design. Because among Christians of both confessions the percentage
of anti-evolutionists is much larger than among atheists, I suggest that religious indoctrination of children may in part
be responsible for the rejection of the concept of evolution, notably in the western part of Germany.

Sub-Antarctic Marion Island has had a permanent research station for 50 years and the islands Wandering Albatrosses have been intensively studied for 20 years. The reactions of breeding birds to approaches by a human on foot were recorded. Three response variables were calculated: intensity of vocal reaction (IVR), intensity of non-vocal reaction (INR) and overall response index (ORI). At 5 m from the nest, twice as many birds stood and/or vocalised as at 15 m. Nearest neighbour distance, age and gender did not explain individual variability of responses. Study colony birds had higher IVR scores than non-study colony birds; birds at colonies closest to the station had the highest ORI scores. A better breeding record was associated with lower IVR and ORI scores, but a causative relationship remains to be demonstrated. A minimum viewing distance of 25 m is recommended for breeding Wandering Albatrosses.

Evolutionary developmental biology (Evo-Devo) is a new and rapidly developing field of biology which focuses on questions
in the intersection of evolution and development and has been seen by many as a potential synthesis of these two fields. This
synthesis is the topic of the books reviewed here. Integrating Evolution and Development (edited by Roger Sansom and Robert
Brandon), is a collection of papers on conceptual issues in Evo-Devo, while From Embryology to Evo-Devo (edited by Manfred
Laubichler and Jane Maienschein) is a history of the problem of the relations between ontogeny and phylogeny.

Threatened species and the spatial concentration of humans 总被引:1,自引:1,他引:0
Public policies that encourage high-density human living arrangements have been predicated explicitly on the assumption that
certain spatial distributions of a fixed-size human population are less environmentally damaging than others. We examine the
empirical validity of this assumption across 127 countries by analyzing whether the concentration of human presence in each
country is related statistically to the percentage of species that were on the IUCN Red List in 2004. Our findings indicate
that concentration of the human population is associated with reduced imperilment among amphibians but increased imperilment
among reptiles, and birds.

The importance of mate choice and sexual selection has been emphasized by the majority of evolutionary psychologists. This
paper assesses three cases of work on mate choice and sexual selection in evolutionary psychology: David Buss on cross-cultural
human mate preferences, Randy Thornhill and Steve Gangestad on the link between mate preferences and fluctuating asymmetry,
and Geoffrey Miller on the role of Fisher’s runaway process in human evolution. A mixture of conceptual and empirical problems
in each case highlights the general weakness of work in evolutionary psychology on these issues.

In the United States, the racial and ethnic statistics published by the National Center for Health Statistics (NCHS) assume
that each member of the U.S. population has a race and ethnicity and that if a member is black or white with respect to his
risk of one disease, he is the same race with respect to his risk of another. Such an assumption is mistaken. Race and ethnicity
are taken by the NCHS to be an intrinsic property of members of a population, when they should be taken to depend on interest.
The actual or underlying race or ethnicity of members of a population depends on the risk whose variation within the population
we wish to describe or explain.

The explanatory filter is a proposed method to detect design in nature with the aim of refuting Darwinian evolution. The explanatory filter borrows
its logical structure from the theory of statistical hypothesis testing but we argue that, when viewed within this context,
the filter runs into serious trouble in any interesting biological application. Although the explanatory filter has been extensively
criticized from many angles, we present the first rigorous criticism based on the theory of mathematical statistics.

Recent papers by a number of philosophers have been concerned with the question of whether natural selection is a causal process,
and if it is, whether the causes of selection are properties of individuals or properties of populations. I shall argue that
much confusion in this debate arises because of a failure to distinguish between causal productivity and causal relevance.
Causal productivity is a relation that holds between events connected via continuous causal processes, while causal relevance
is a relationship that can hold between a variety of different kinds of facts and the events that counterfactually depend
upon them. I shall argue that the productive character of natural selection derives from the aggregation of individual processes
in which organisms live, reproduce and die. At the same time, a causal explanation of the distribution of traits will necessarily
appeal both to causally relevant properties of individuals and to causally relevant properties that exist only at the level
of the population.

This paper critically reviews and characterizes the student's causal-explanatory understanding; this is done as a step toward
explicating the problematic of evolution education as it concerns the cognitive difficulties in understanding Darwin's theory of natural selection. The review concludes that the student's understanding is fundamentally different from Darwin's, for
the student understands evolutionary change as necessary individual transformation caused by the transformative action of
various physical and behavioral factors. This is in complete contrast to Darwin's (and even the Darwinian's, for that matter)
understanding of evolutionary change as a change caused by accumulative selection. Hence, to understand natural selection,
the student has to learn to “see” how the accumulative selection causes evolutionary change.

On the basis of distinctions between those properties of entities that can be defined without reference to other entities
and those that (in different ways) cannot, this note argues that non-trivial forms of frequency-dependent selection of entities
should be interpreted as selection occurring at a level higher than that of those entities. It points out that, except in
degenerately simple cases, evolutionary game-theoretic models of selection are not models of individual selection. Similarly,
models of genotypic selection such as heterosis cannot be legitimately interpreted as models of genic selection. The analysis
presented here supports the views that: (i) selection should be viewed as a multi-level process; (ii) upper-level selection
is ubiquitous; (iii) kin selection should be viewed as a type of group selection rather than individual selection; and (iv)
inclusive fitness is not an individual property.

To our knowledge, this paper is the first record/report of a juvenile light-coloured Weddell seal (Leptonychotes weddellii) at Cape Shirreff, Livingston Island in January 1998, determining that it was an albino individual. Based on available literature,
three cases of albino seals have been reported exclusively for Harbour seal pups, and no albino has been reported for Antarctic
pagophilic true seals. Therefore, this is the first confirmed case of albinism in Antarctic pagophilic true seals species,
indicating that this phenomenon is indeed of a rare occurrence.

The origin of complex biological structures has long been a subject of interest and debate. Two centuries ago, natural explanations
for their occurrence were considered inconceivable. However, 150 years of scientific investigation have yielded a conceptual
framework, abundant data, and a range of analytical tools capable of addressing this question. This article reviews the various
direct and indirect evolutionary processes that contribute to the origins of complex organs. The evolution of eyes is used
as a case study to illustrate these concepts, and several of the most common misconceptions about complex organ evolution
are discussed.

Jablonka and Lamb's claim that evolutionary biology is undergoing a ‘revolution’ is queried. But the very concept of revolutionary
change has uncertain application to a field organized in the manner of contemporary biology. The explanatory primacy of sequence
properties is also discussed.

Creationist Teaching in School Science: A UK Perspective 总被引:1,自引:0,他引:1
James David Williams 《Evolution》2008,1(1):87-95
The creation/evolution controversy in UK schools made headlines in the national press, on TV, and radio in 2002. Claims were
made that creationism was being taught in schools. This article looks at the impact this controversy had on the UK government
and how creationism is trying to gain ground in UK state schools by introducing students to Intelligent Design through promotional
DVDs. Student attitude surveys eliciting views toward science and religion are examined. Concern is also expressed at how
the teaching of evolution through standard textbooks may not deliver a persuasive case for evolutionary theory. The article
concludes with a number of implications for researchers, teachers, and schools.
