Evidences of Evolution

Front

What is the law of superposition?

Back

The law of superposition states that in any undisturbed sequence of rocks, the oldest layers are at the bottom and the youngest layers are at the top.

Front

Which layer is the youngest according to the law of superposition?

Back

The youngest layer is the one at the top of the sequence.

Front

What is an example of a close evolutionary relationship?

Back

Humans and chimpanzees share a closer evolutionary relationship compared to humans and gorillas.

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that have a similar structure but may serve different functions, indicating a common ancestor.

Front

Give an example of homologous structures.

Back

Whale flippers and bat wings are examples of homologous structures.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that have similar functions but different structures, indicating no common ancestry.

Front

Give an example of analogous structures.

Back

Bee wings and bird wings are examples of analogous structures.

Front

What is embryology?

Back

Embryology is the study of embryos and their development, providing evidence for evolutionary relationships.

Front

What is the fossil record?

Back

The fossil record is the history of life on Earth as documented by fossils, showing the progression of species over time.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the human appendix.
