Evolution by natural selection
The Darwinian theory that evolution proceeds by differential success in reproduction
Adaptation
A trait that increases the probability that an individual will leave offspring in subsequent generations
Sexual selection
Darwin’s theoretical mechanism for the evolution of anatomical and behavioral differences between males and females
Convergent evolution
The evolutionary process by which responses to similar ecological features bring about similarities in behavior or structure among animals that are only distantly related (i.e., that differ in genetic heritage).
