Evolution curricula are replete with information about Darwin's theory of evolution as well as microevolutionary mechanisms underlying this process of change. However, other fundamental facets of evolutionary theory, particularly those related to macroevolution are often missing. One crucial idea typically ...
Why does evolution take so long to occur? How similar are the genomes of humans and chimpanzees? What genetic changes might be responsible for the large differences in the anatomy, physiology, and behavior of humans and chimpanzees? Explore our homework questions and answers...
Evolution is the backbone of modern biological studies as it provides the unifying framework within which all biologists, from a diversity of branches and subdisciplines, ask questions about the living world. A basic understanding of central evolutionary concepts is thus considered essential for biologic...
With respect to gene flow, it is important to distinguish between interspecific and intraspecific questions regarding history and evolution. For questions regarding multiple species (e.g., the Hominoids), it is typically assumed that gene flow between species is essentially nonexistent. One consequence...

This raises a number of additional questions, but of particular importance: is the acoustic communication of choanates an innovation homologous to the acoustic communication based on the swim bladder observed in fishes? If so, did acoustic communication first appear among actinopterygians or in the...
Organic Evolution: The fossil record indicates that life has changed over time. It also shows that modern life forms are more complex than their ancient ancestors. This phenomenon is known as evolution and its mechanism was proposed by Charles Darwin. ...
In addition, we demonstrate considerable feasibility to work on this species as a model for a range of pertinent questions in evolution and ecology. We revealed that different tissues of different sexes of this butterfly species respond differently across temperatures, including differences in the ...
