What is a common ancestor?

Back

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

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring, often referred to as 'survival of the fittest'.

Front

What is embryology?

Back

Embryology is the study of embryos and their development, which can provide evidence for evolutionary relationships.

Front

What is a bottleneck event?

Back

A bottleneck event is a sharp reduction in the size of a population due to environmental events or human activities, leading to a loss of genetic diversity.

Front

What is genetic variation?

Back

Genetic variation refers to the diversity in gene frequencies within a population, which is essential for natural selection.

Front

What is the founder effect?

Back

The founder effect occurs when a small group of individuals becomes isolated from a larger population, leading to reduced genetic diversity.

Front

What is the tree of life?

Back

The tree of life is a metaphor that illustrates the evolutionary relationships among various species, showing how they are connected through common ancestry.

Front

What is adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species due to evolutionary changes.
