Biological Concepts and Evolutionary Processes Quiz

Charles Darwin is credited with proposing the theory of evolution by natural selection.

Natural selection is the process by which organisms evolve and adapt to their environment over time.

Species is the term for a group of organisms capable of interbreeding and producing fertile offspring.

Pangenesis is NOT a mechanism of evolution.

The appendix is an example of a vestigial structure in humans.

Homologous structures are structures with different functions but similar evolutionary origins.

The wings of bats and birds are an example of convergent evolution.

Jean-Baptiste Lamarck proposed the theory of inheritance through 'blending'.

Allele frequency in evolution refers to the proportion of individuals in a population that carry a particular allele.

A symbiotic relationship between bees and flowers is an example of coevolution.

Genetic drift is a mechanism of evolutionary change more pronounced in small populations, involving random fluctuations in allele frequencies.

Punctuated equilibrium is a sudden burst of evolutionary change followed by long periods of stasis in evolutionary biology.

Convergent evolution is the process by which two separate species evolve to resemble each other due to similar ecological roles and selection pressures.

Gene flow is the term for the change in allele frequencies in a population due to individuals moving in or out of the population.

The founder effect is when a small group of individuals migrates to a new area, establishing a new population with a different allele frequency than the original population.
