(Q4) LS - Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution includes fossil records, DNA similarities, and anatomical structures that show how species have changed over time.

Front

What does a very similar DNA sequence indicate about two organisms?

Back

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

Front

What is DNA used for in evolutionary biology?

Back

DNA is used to find common proteins and amino acids to determine how closely related species are.

Front

What are homologous structures?

Back

Structures in different species that have the same parts but different functions, suggesting a common ancestry.

Front

What type of fossil formation involves the replacement of organic material with minerals?

Back

Mineralization.

Front

What is embryology?

Back

The study of embryos of various organisms to show similarities in development, indicating a common ancestor.

Front

What are vestigial structures?

Back

Structures that have lost their original function through evolution, such as the human appendix.

Front

What is adaptive radiation?

Back

The process by which organisms diversify rapidly into a variety of forms to adapt to different environments.

Front

What are trace fossils?

Back

Fossils that provide evidence of the activity of organisms, such as footprints or burrows.

Front

What is the significance of fossil records in evolution?

Back

Fossil records provide evidence of how species have changed over time and can show transitional forms.
