Evolution

Front

What is a mutation?

Back

A mutation is a random change in the DNA of a gene that can lead to genetic variation.

Front

What is a fossil?

Back

A fossil is a trace of an organism that existed in the past.

Front

What is variation in biology?

Back

Variation refers to the differences in physical traits among individuals in a group.

Front

What are the five factors of evolution?

Back

The five factors of evolution are gene flow, genetic drift, mutation, natural selection, and non-random mating.

Front

Why are mutations important for evolution?

Back

Mutations are important because they provide the genetic variation needed for a population to evolve.

Front

What is gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can affect genetic diversity.

Front

What is genetic drift?

Back

Genetic drift is a random change in allele frequencies in a population, often having a more significant effect in small populations.

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 non-random mating?

Back

Non-random mating occurs when individuals select mates based on specific traits, influencing the genetic structure of the population.

Front

What is an adaptation?

Back

An adaptation is a trait that enhances an organism's ability to survive and reproduce in its environment.
