4-1 Evidence For Evolution Flashcard

Front

What do all living things on Earth share at a molecular level?

Back

Shared molecular sequences and use DNA or RNA as genetic information.

Front

What is essential for genetic diversity in evolution?

Back

Sexual reproduction and/or mutations.

Front

Which two macromolecules provide evidence for evolution by showing shared molecular traits?

Back

DNA and RNA.

Front

What evidence is used to construct phylogenetic trees?

Back

Morphological, genetic, and biochemical data.

Front

What method is used to infer the age of fossils from the fossil record?

Back

Inferring age and relationships based on where fossils are located within sedimentary rock layers.

Front

What is the common ancestor theory in evolution?

Back

The theory that all living organisms share a common ancestor.

Front

What role do mutations play in evolution?

Back

Mutations introduce genetic variation, which is essential for evolution.

Front

How does sexual reproduction contribute to evolution?

Back

It increases genetic diversity, allowing for more variation in traits.

Front

What is a phylogenetic tree?

Back

A diagram that shows the evolutionary relationships among various biological species.

Front

What is the significance of DNA in evolutionary biology?

Back

DNA carries genetic information and shows similarities among different species.
