EvoGrader will be of interest to biology instructors teaching large classes who seek to emphasize scientific practices such as generating scientific explanations, and to teach crosscutting ideas such as evolution and natural selection. The software architecture of EvoGrader is described as it may serve...
Evolution as a genetic function The concept ofnatural selection The central argument of Darwin’s theory of evolution starts with the existence of hereditaryvariation. Experience withanimalandplant breedinghad demonstrated to Darwin that variations can be developed that are “useful to man.” So, he...
Again, defectors can be separated into different types as a function of the maximum ratio of benefit to cost required for them to be ESS. First, the defectors that are ESS for the whole range of benefit studied (D1–D16) never cooperate with each other nor with the mutant. They are ...
Shouldered points with their distinct morphological structure can be described as a latero-frontally hafted implement. While the tip is located frontally, the lateral edge opposite of the shoulder can protrude from the shaft (Lund, 1993; Weber, 2009; Kufel-Diakowska et al., 2016). Shouldered ...
A tantalizing question in evolutionary biology is whether evolution can be predicted from past experiences. To address this question, we created a coherent compendium of more than 15,000 mutation events for the bacterium Escherichia coli under 178 distin
How can a trait be identified as an adaptation? http://evolution.berkeley.edu/evolibrary/article/qualifying_01 If it is not an adaptation, what is it? http://evolution.berkeley.edu/evolibrary/article/misconcep_07Dig Deeper To learn more about the exaptations that four-legged vertebrates have...
Second, Alangium has long been recog- nized as a family, Alangiaceae DC. (de Candolle, 1828). Third, the name of Alangiaceae has been proposed to be conserved (Bullock, 1959; APG, 2003). Cornaceae s.s. consists of approximately 50–55 species that are morphologically diverse. ...
Mitochondrial genomes were assembled and identified as described in the methods, and basic statistics relating to these can be seen in Table 3. The disparity observed in read number did not affect the assembly of complete mtDNA sequence, with all assemblies resulting in easily identifiable complete,...
If we adopt these definitions,beliefis the general term for thinking that a proposition (such as evolution) is true, withacceptancebeing a more restricted subset (Fig.1). The terms “non-belief” and “non-believer” can, however, easily be interpreted as implying some kind of equivalence be...
The downhill sediment transport (\({q}_{s}\)) can be represented as a combination of incorporating sediment transport by (1) channel flow \(({q}_{r})\), which is described by a stream power-law, and (2) long-term slope-driven diffusive processes \(({q}_{d})\), described by...
