In goat breeds, the domestication followed by artificial selection for economically important traits have shaped genetic variation within populations, leading to the fixation of specific alleles for specific tr
What is the difference between an evolutionary selection pressure and a mechanism of natural selection? What is the primary pressure on species to change over time? A) Natural selection B) Mutation C) Adaptation How do selective pressures affect the genetic variation...

Naturally occurring stress, both physical and mental, has a significant negative impact on theimmune system, irrespective of age. Both major and minor stressful events have been shown to have a profound influence on immune responses in both animal and human studies. One of the hallmarks of chroni...

happening right now everywhere around us, and adaptive changes can occur in a population with remarkable speed. This is essential if you're a mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. The film features Dr. Michael N...(展开...
Darwin's process of natural selection. Evolution is happening right now everywhere around us, and adaptive changes can occur in a population with remarkable speed. This is essential if you're a mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an ...
Disruptive Selection Examples: Feeding Ability Evolution and speciation isn't all a straight line. Often there are multiple pressures on a group of individuals, or a drought pressure, for example, that is just temporary, so the intermediate individuals don't completely disappear or don't disappear...
It is clear that proteins are under selective pressure for both stability and function, but to what extent does nature select for proteins that are able to fold quickly into their native states? What benefits may be conferred to the cell by fast protein folding kinetics? It is clearly ...
