Evidence of Evolution

Front

What is the evidence of common ancestry in organisms?

Back

The evidence of common ancestry can be observed through similarities in embryonic development, homologous structures, and genetic similarities among different species.

Front

What is evolution?

Back

Evolution is the process of change in species over time through mechanisms such as natural selection, genetic drift, and mutation.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a similar origin but may serve different functions, indicating a common ancestry.

Front

What are analogous structures?

Back

Analogous structures are features in different species that serve similar functions but do not share a common evolutionary origin.

Front

What are vestigial structures?

Back

Vestigial structures are remnants of organs or structures that had a function in an early ancestor but are no longer functional in the current organism.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which a single ancestral species rapidly diversifies into a wide variety of forms to adapt to different environments.

Front

What is mimicry in evolution?

Back

Mimicry is an evolutionary adaptation where one species evolves to resemble another species for protection or other advantages.

Front

What is the significance of fossil records in evolution?

Back

Fossil records provide evidence of past life forms and show the changes in species over time, supporting the theory of evolution.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.
