A review of evidence on selection strength suggests that although most variance in fitness may be because of alleles with large Nes, substantial amounts of adaptation may be because of alleles in the infinitesimal regime, in which epistasis has modest effects. Heredity (2017) 118, 96–109; doi...
In a range of settings, human operators make decisions with the assistance of automation, the reliability of which can vary depending upon context. Currently, the processes by which humans track the level of reliability of automation are unclear. In the
As mutations occur and spread over long periods of time, they cause new species to form. Over the course of many millions of years, the processes of mutation and natural selection have created every species of life that we see in the world today, from the simplest bacteria to humans and ...
How is gene flow related to genetic drift? How are convergent evolution and evolution by common descent different? Why is genetic drift stronger in small populations? Does genetic drift increase evolution? What is the relationship between mutation, natural selection and adaptation? Is genetic drift ...
Squids are shrinking, birds are migrating and lizards are getting blown away by hurricanes. The signs are everywhere; animals are changing because of climate change. We asked biologist Thor Hanson to walk us through three animal adaptation experiments.Re
Inducible metabolic adaptation promotes mesenchymal stem cell therapy for ischemia: a hypoxia-induced and glycogen-based energy prestorage strategy. Arterioscler Thromb Vasc Biol. 2014;34:870–6. https://doi.org/10.1161/ATVBAHA.114.303194. Article CAS PubMed Google Scholar Shuai Y, Liao L, Su ...
When running a randomized controlled trial (RCT), a clinical site may face a situation when an eligible trial participant is to be randomized to the treatment that is not available at the site. In this case, there are two options: not to enroll the parti
Artificial life: The concept of artificial life is closely related to the idea of creating entities that exhibit characteristics typically associated with living organisms, such as adaptation, reproduction, and evolution. While AI models can display some of these features, the distinction between artific...
This may also hinder adaptation to a changing environment. However, our study results indicate that male equal access to females may, at least partially, counter the inhibition effect on a beneficial mutation establishment. More research is necessary in order to investigate female reproductive skew ...
A change in allele frequencies in a population that does not result from adaptation or natural selection. a. reproductive isolation b. sexual selection c. directional selection e. genetic drift f. founder effect What are the two main ...
