Comparative Anatomy

Front

What are analogous structures?

Back

Structures in different species that have similar functions but different evolutionary origins.

Front

What do analogous structures suggest about evolution?

Back

They suggest that organisms independently evolved similar solutions to adapt to environmental challenges.

Front

What are homologous structures?

Back

Structures in different species that share a common ancestry but may serve different functions.

Front

What does the similarity in bone structure of forelimbs in different species indicate?

Back

It suggests that these species share a common evolutionary ancestry.

Front

What are vestigial structures?

Back

Remnants of organs or structures that were functional in ancestral species but are no longer useful.

Front

What evidence do fossil records provide in the study of evolution?

Back

They provide evidence of the physical changes in organisms over time.

Front

Why are homologous structures important in comparative anatomy?

Back

They provide insight into the evolutionary relationships between species.

Front

What is the significance of studying comparative anatomy?

Back

It helps scientists understand the evolutionary history and relationships among different organisms.

Front

How do environmental challenges influence evolution?

Back

They drive natural selection, leading to adaptations in organisms.

Front

What is natural selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.
