6-2 and 6-3 Evolution Quiz

when two organisms, such a predator and prey, evolve in response to one another

slow changes in allele frequencies over a long period of time

rapid evolutionary change followed by periods of stability

when unrelated species evolve similar characteristics (analogous) because they live in similar environments

sudden elimination of a species due to a catastrophic event

when isolation causes two populations of organisms to become so different they can no longer reproduce with each other and produce viable offspring

takes 2 organisms to make offspring; process of meiosis to create gametes

process of binary fission; mitosis where only one parent produces identical offspring

divergent evolution; the evolution of many diverse species from a common ancestor; they have homologous structures

remnant of organisms such as imprints, bones and feces

the fossil record shows a period of stability in a species showing little evolutionary change

the study of prehistoric life that allows scientists to make connections between current and extinct species

study of the physical geographic distribution of plants and animals

study of embryo development in vertebrates that has led to the support of common ancestry; presence of gills and tails

body structures that are similar in orientation, but completely different in function due to living in different environments; evidence of common ancestor; example is human arm, cat leg, bat wing, whale flipper
