Evolution Review

The study of organisms at an early stage of development that provides evidence of possible common ancestors between 2 different species.

• paleontology

• embryology

• genetic variation

• homologous structures

Organs/structures found on different organisms that have similar structures but have evolved different uses for these structures

• embryology

• vestigial structures

• homologous structures

• paleontology

The study of extinct life.

• paleontology

• embryology

• biology

• archaeology

Organs/structures that have been reduced in size in an organism that suggests that they adapted to life without their use.

• homologous structure

• embryology

• vestigial structure

• similar structure

First to propose that evolution occurs naturally when individuals best suited to the environment survive and reproduce

• Gregor Mendel

• Alfred Wagoner

• Louis Pasteur

• Charles Darwin

NGSS.MS-LS4-4

A change in DNA sequence, usually occurring because of errors in replication or repair.

• Deletion

• Substitution

• Duplication

• Mutation

The chance of an individual migrating to another population and sharing its genes there.

• genetic drift

• genetic flow

• genetics

• gene therapy

genetic drift is when

• the frequency of alleles change due to random events like habitat destruction which results in changes in successive generations.

• a change in DNA sequences occurs due to errors in replication or repair

• evolution of traits result in better fitness of an individual and survival to the next generation.

• human breeders, rather than the environment select the variations of traits to be passed to offspring.

When organisms within a population will have differences.

• diversity

• overproduction

• adaptation

• variation

more organisms will be produced than will survie

• sexual reproduction

• successful reproduction

• overproduction

• asexual reproduction
