Evolution

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA sequences among individuals within a population, which can lead to different traits.

Front

What are the main mechanisms of evolution?

Back

The main mechanisms of evolution include natural selection, mutation, gene flow, and genetic drift.

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 definition of evolution?

Back

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

Front

What is an inherited trait?

Back

An inherited trait is a characteristic that is passed from parents to offspring through genes.

Front

What role do predators play in natural selection?

Back

Predators can influence natural selection by affecting which individuals survive and reproduce based on their traits.

Front

What is the significance of studying embryos in evolutionary biology?

Back

Studying embryos helps scientists understand the developmental similarities and differences among species, indicating evolutionary relationships.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to new traits in an organism.

Front

How does gene flow contribute to evolution?

Back

Gene flow is the transfer of genetic material between populations, which can introduce new genetic variation and affect evolutionary processes.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in allele frequencies in a population, often having a more significant effect in small populations.
