Front

Define sympatric speciation.

Back

Sympatric speciation is the process of speciation that occurs when populations are in the same geographic area but evolve differently due to other factors.

Front

What is the concept of fitness in evolutionary biology?

Back

Fitness refers to an organism's ability to survive and reproduce in its environment, contributing to the gene pool of the next generation.

Front

What is the role of mutations in evolution?

Back

Mutations introduce genetic variation, which can lead to new traits that may be beneficial for survival and reproduction.

Front

What is reproductive success?

Back

The passing of genes to the next generation, often measured by the number of offspring produced that survive to reproduce.

Front

What is the importance of genetic variation in a population?

Back

It provides the raw material for natural selection, allowing populations to adapt to changing environments.

Front

Define 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 allopatric speciation?

Back

Allopatric speciation occurs when a population is divided by a physical barrier, leading to the formation of new species.

Front

Explain the concept of adaptation.

Back

Adaptation is a trait that increases an organism's fitness in a specific environment, enhancing its chances of survival and reproduction.

Front

What is gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can introduce new alleles and increase genetic diversity.

Front

Define genetic drift.

Back

Genetic drift is a mechanism of evolution that refers to random changes in allele frequencies within a population.
