Theory of evolution

Front

What is the theory of evolution?

Back

The theory of evolution explains how species change over time through processes like natural selection and genetic variation.

Front

What is a common ancestor?

Back

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

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that share a similar origin but may have different functions.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that perform similar functions but do not share a common origin.

Front

What are vestigial structures?

Back

Vestigial structures are remnants of organs or structures that had a function in an early ancestor but are no longer used in the same way.

Front

What role do mutations play in evolution?

Back

Mutations introduce genetic variation, which is essential for a population to evolve.

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.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population, which is crucial for evolution.

Front

What is the significance of embryonic similarities in different species?

Back

Embryonic similarities suggest that different species share a common ancestry.

Front

What is the Hardy-Weinberg equilibrium?

Back

The Hardy-Weinberg equilibrium is a principle that describes a population that is not evolving, where allele frequencies remain constant.
