Evidences & Mechanisms of Evolution

Front

What are Analogous Structures?

Back

Structures that are similar in appearance but not in structure, often due to convergent evolution.

Front

What is a Homologous Structure?

Back

Structures that are similar in structure and origin but may serve different functions, indicating a common ancestor.

Front

What is Gene Flow?

Back

The transfer of genetic material between populations, often through migration and mating.

Front

What is Genetic Drift?

Back

A mechanism of evolution that involves random changes in allele frequencies within a population.

Front

What is Natural Selection?

Back

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

Front

What is a Vestigial Structure?

Back

A structure that has lost most or all of its original function through the course of evolution.

Front

What is a Common Ancestor?

Back

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

Front

What is Non-Random Mating?

Back

A mating pattern where individuals select partners based on specific traits, affecting allele frequencies.

Front

What is the significance of DNA comparison in evolution?

Back

It supports the theory that all species share a common ancestor by showing genetic similarities.

Front

What is the difference between Homologous and Analogous Structures?

Back

Homologous structures share a common ancestry, while analogous structures do not and arise from convergent evolution.
