Evidence of Evolution

Front

What is the evidence that the opossum and kangaroo are descended from a common ancestor?

Back

Both incubate their young in a pouch, indicating a shared evolutionary trait.

Front

What are analogous structures?

Back

Structures that are similar in appearance but not in structure, often due to convergent evolution.

Front

What is an example of an analogous structure?

Back

Wings of bats and wings of insects, which serve the same function but have different structural origins.

Front

What is evolution?

Back

A change in the inherited characteristics of an organism over time.

Front

What is the fossil record?

Back

The collection of life's remains found in sedimentary rock, providing evidence of past life forms.

Front

What are homologous structures?

Back

Structures that are similar in structure but may serve different functions, indicating a common ancestor.

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 are vestigial organs?

Back

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

Front

What is the significance of embryonic development in evolution?

Back

Similarities in embryonic development among different species can indicate common ancestry.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common ancestry but may have different functions, while analogous structures serve similar functions but do not share a common ancestry.
