Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory that species change over time through processes such as natural selection and genetic drift.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even though they may serve different functions.

Front

What is a common ancestor?

Back

A common ancestor is a species from which two or more different species have evolved.

Front

How do fossils provide evidence for evolution?

Back

Fossils provide evidence for evolution by showing how life forms present today are different from those in the past, indicating changes over time.

Front

What are vestigial structures?

Back

Vestigial structures are anatomical features that have lost most or all of their original function through the course of evolution.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a wide variety of forms to adapt to different environments.

Front

What is the significance of embryonic similarities in different species?

Back

Embryonic similarities suggest that different species share a common ancestry, as they exhibit similar developmental stages.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures arise from a common ancestor, while analogous structures have 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 role of genetic variation in evolution?

Back

Genetic variation is essential for evolution as it provides the raw material for natural selection to act upon.
