Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory of evolution, including fossil records, genetic similarities, and anatomical structures.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions (e.g., the forelimbs of humans and whales).

Front

What are analogous structures?

Back

Analogous structures are features in different species that serve similar functions but do not share a common ancestry (e.g., wings of birds and insects).

Front

What are vestigial organs?

Back

Vestigial organs are body parts that have lost their original function through evolution (e.g., the human appendix).

Front

What is a subspecies?

Back

A subspecies is a population of the same species that has diverged genetically due to adaptation to different environments.

Front

What is the significance of DNA similarity in evolution?

Back

DNA similarity among species indicates a common ancestry and helps scientists understand evolutionary relationships.

Front

What is the role of fossils in understanding evolution?

Back

Fossils provide historical evidence of past life forms and their changes over time, helping to trace the evolution of species.

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 genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a variety of forms to adapt to different environments.
