How natural selection influences discrete traits? How does nonrandom mating affect evolution? As natural selection increases the frequency of one morphological form over another in the population, what changes at the genotypic level? How does genetic drift cause a population to...
How natural selection influences discrete traits? What is natural selection? How does it work, and how does it compare to artificial selection? What role does natural variation play in the process of natural selection and ultimately evolution? In what ways is artificial selection different from nat...

Results from Experiment 1 show that the degree to which member group and aspiration group usage influences individual self-brand connections is contingent on the degree to which the individual belongs to a member group or wishes to belong to an aspiration group. In Experiment 2, we found that ...
Researchers analyze how an independent variable influences a dependent variable, but they do not manipulate the independent variable. Instead, they observe and compare different groups to conclude. Causal-comparative research is useful when it’s not ethical or feasible to conduct true experiments. ...
Ranging from food production to energy, nature influences economic wealth. Although early humans gathered uncultivated plant materials for food and employed the medicinal properties of vegetation for healing,[68] most modern human use of plants is through agriculture. The clearance of large tracts of ...
Global policy initiatives and international conservation organizations have sought to emphasize and strengthen the link between the conservation of natural ecosystems and human development. While many indices have been developed to measure various social
