Evidence of Evolution

Front

What is the evidence of evolution?

Back

Evidence of evolution includes fossil records, comparative anatomy, molecular biology, and biogeography that support the theory of evolution.

What is a homologous structure?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

Front

What is an analogous structure?

Back

Analogous structures are features in different species that serve similar functions but do not share a common ancestry.

Front

What are vestigial structures?

Back

Vestigial structures are anatomical remnants that were important in the organism's ancestors but are no longer used in the same way.

Front

What is the Hardy-Weinberg principle?

Back

The Hardy-Weinberg principle describes the genetic equilibrium in a population, stating that allele frequencies will remain constant in the absence of evolutionary influences.

Front

What are the conditions for Hardy-Weinberg equilibrium?

Back

The conditions include a large population, no immigration or emigration, no natural selection, random mating, and no genetic mutations.

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 significance of fossil records in evolution?

Back

Fossil records provide chronological evidence of past life forms and show how species have changed over time.

Front

What is comparative anatomy?

Back

Comparative anatomy is the study of similarities and differences in the anatomy of different species, providing insights into evolutionary relationships.

Front

What is biogeography?

Back

Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time, supporting the theory of evolution.
