Evolution and Structure in Biology

Front

What is embryology?

Back

The study of embryos and their development.

Front

What are analogous structures?

Back

Features of different species that are similar in function but not in structure.

Front

What are homologous structures?

Back

Similar features in organisms with different functions.

Front

What kingdom under the domain Eukarya includes heterotrophic decomposers with cell walls made of chitin?

Back

Fungi.

Front

What kingdom under the domain Eukarya consists of multicellular eukaryotes that are heterotrophic and lack cell walls?

Back

Animalia.

Front

What is natural selection?

Back

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

Front

Define evolution in biological terms.

Back

The change in the heritable characteristics of biological populations over successive generations.

Front

What is the significance of genetic variation in evolution?

Back

Genetic variation is essential for natural selection, as it provides the raw material for evolution.

Front

What is the difference between convergent and divergent evolution?

Back

Convergent evolution occurs when unrelated species develop similar traits, while divergent evolution occurs when related species evolve different traits.

Front

What is speciation?

Back

The formation of new and distinct species in the course of evolution.
