Evolution

Front

What are analogous structures?

Back

Structures that have evolved separately in two species and were not inherited from a common ancestor.

Front

What are homologous structures?

Back

Features in organisms that share a common ancestor but have different functions.

Front

What is embryology?

Back

The study of organisms at the early stages of development.

Front

What is gradualism in evolution?

Back

The hypothesis that evolution occurs gradually over time as a slow and constant process.

Front

True or False: Individuals undergo evolution.

Back

False. Evolution occurs at the population level, not at the individual level.

Front

What are vestigial structures?

Back

Structures that have lost their original function through evolution.

Front

What is the difference between microevolution and macroevolution?

Back

Microevolution refers to small evolutionary changes within a species, while macroevolution refers to larger evolutionary changes that can lead to the formation of new species.

Front

What is natural selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is speciation?

Back

The process by which new species arise from existing species.

Front

What is punctuated equilibrium?

Back

The theory that evolution occurs in rapid bursts followed by long periods of stability.
