Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory of evolution, including fossil records, genetic similarities, and anatomical structures.

Front

What does it mean when two organisms have very similar DNA sequences?

Back

It indicates that the organisms are closely related and share a common ancestor.

Front

What is extinction?

Back

Extinction is the process in which all members of a species die out.

Front

What are subspecies?

Back

Subspecies are populations of the same species that differ genetically due to adaptation to different environments.

Front

What are variations in a species?

Back

Variations are slight differences among individuals of the same species, such as differences in color or size.

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 adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of an organism that lived in the past.

Front

What is the significance of homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, indicating evolutionary relationships.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures arise from a common ancestor, while analogous structures serve similar functions but do not share a common ancestry.
