Evidence of Evolution

Front

What is the evidence of evolution?

Back

Evidence of evolution includes fossil records, homologous structures, vestigial structures, and observed changes in species over time.

Front

What is the fossil record?

Back

The fossil record is the collection of remains of ancient life forms found in sedimentary rock, providing evidence of the history of life on Earth.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the tailbone in humans.

Front

What are analogous structures?

Back

Analogous structures are features in different species that serve similar functions but do not share a common ancestry.

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 the significance of Charles Darwin in evolution?

Back

Charles Darwin is known for his theory of evolution by natural selection, which explains how species evolve over time.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures arise from a common ancestor, while analogous structures arise independently in different species.

Front

What is an example of a vestigial structure in humans?

Back

The tailbone (coccyx) is an example of a vestigial structure in humans.

Front

What does the term 'common ancestry' mean?

Back

Common ancestry refers to the idea that different species share a common ancestor from which they have evolved.
