Evidences of Evolution

Front

What are homologous structures?

Back

Structures in different species that are similar due to shared ancestry, such as the forelimbs of mammals.

Front

What is the significance of embryonic development similarities in evolution?

Back

It suggests that organisms may have evolved from a common ancestor.

Front

What is a vestigial structure?

Back

A structure that has lost most or all of its original function through the course of evolution, like the remnants of an eye in cave fish.

Front

Give an example of homologous structures.

Back

Whale flipper and bat wing are homologous structures.

Front

What is evolution?

Back

A change in a species over time, leading to adaptations and diversity.

Front

What are analogous structures?

Back

Structures that serve similar functions but do not share a common ancestry, like the wings of bees and birds.

Front

Define adaptation in the context of evolution.

Back

A trait that increases an organism's fitness in its environment, often resulting from evolutionary processes.

Front

What is the role of fossil evidence in evolution?

Back

Fossils provide historical evidence of past life forms and their changes over time, supporting the theory of evolution.

Front

What does the term 'common ancestor' mean?

Back

An ancestral species from which two or more species have evolved.

Front

How do genetic similarities support the theory of evolution?

Back

Similarities in DNA sequences among different species indicate a shared ancestry and evolutionary relationships.
