Students have asked these similar questions
Compare and contrast gradualism with punctuatedequilibrium.
compare and contrast between the following
a) allopatric speciation and sympatric speciation.
b) autopolyploid speciation and allopolyploid speciation
c) natural selection and sexual selection
Consider two species that diverged while geographically separated but resumed contact before reproductive isolation was complete. Predict the outcome over time if the two species mated indiscriminately and (a) hybrid offspring survived and reproduced more poorly than offspring from intraspecific matings or (b) hybrid offspring survived and reproduced as well as offspring from intraspecific matings.
