selection
the evolutionary process where organisms with traits better suited to their environment tend to survive and reproduce more successfully, leading to the increase in frequency of those traits in future generations.
what is natural selection
body part that is similar in function as a body part of another organism but is structurally different
what are analogous structures
occurs when natural selection favors one of the extreme variations of a trait
what is directional selection
The comparison of body structures and how they vary among species
what is comparative anatomy
form of natural selection in which a single curve splits into two; occurs when individuals at the upper and lower ends of a distribution curve have higher fitness than individuals near the middle
what is disruptive selection
Structures in different species that are similar because of common ancestry
what are homologous structures
Natural selection that favors intermediate variants by acting against extreme phenotypes
what is stabilizing selection
structure that is inherited from ancestors but has lost much or all of its original function
what is a vestigial structure
the selective breeding of organisms by humans for specific characteristics
what is artificial selection
