SB6 vocab

Match the following

• natural selection

• organisms best adjusted to their environment are the most successful in surviving and reproducing

• descent with modification

• process through which populations of living organisms adapt and change

• fitness

• reproductive success and reflects how well an organism is adapted to its environment

• survival of the fittest

• introduction of genetic material from one population to another

• gene flow

• idea that species change over time, give rise to new species, and share a common ancestor

Match the following

• reproductive isolation

• inability of a species to breed successfully with related species due to geographical, behavioral or genetic barriers

• genetic drift

• random fluctuations in frequency of a particular version of a gene

• bottleneck effect

• condition of an allele where the frequency does not change from generation to generation

• genetic equilibrium

• genetic variability that occurs when a small group of individuals becomes separated from a larger population

• founder effect

• occurs when a population's size is reduced, genetic variation is reduced due to environmental events

Match the following

• homologous structures

• features of different species that are similar in function but not in structure and do not derive from a common ancestor

• vestigial structures

• similar physical features in organisms that share a common ancestor, but features serve completely different functions

• analogous structures

• structure that has lost a major ancestral function and is drastically reduced in size

Match the following

• divergent evolution

• rapid increase in the number of species with a common ancestor, characterized by great ecological and morphological diversity

• adaptive radiation

• process where organisms not closely related, independently evolve similar traits

• convergent evolution

• process by which interbreeding species diverged into two or more evolutionary groups
