DownloadWhat is natural selection?
Omdraaien
Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. This mechanism drives evolutionary change.
Who proposed the theory of natural selection?
Omdraaien
Charles Darwin and Alfred Russel Wallace independently proposed the theory of natural selection.
What is genetic drift?
Omdraaien
Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population, particularly in small populations.
How does genetic drift differ from natural selection?
Omdraaien
Genetic drift is random and affects allele frequencies by chance, while natural selection is a non-random process where alleles that confer a survival or reproductive advantage become more common.
What is a population in biological terms?
Omdraaien
A population is a group of individuals of the same species that live in the same area and interbreed, producing fertile offspring.
Define speciation.
Omdraaien
Speciation is the evolutionary process by which populations evolve to become distinct species.
What are the two main types of speciation?
Omdraaien
The two main types of speciation are allopatric speciation (occurring via geographic isolation) and sympatric speciation (occurring without geographic isolation).
What is allopatric speciation?
Omdraaien
Allopatric speciation occurs when a population is divided by a geographic barrier, leading to the evolution of separate species due to isolation.

Als ouder heb ik het gedeelte m.b.t. bijles bekeken, deze functie is goed overzichtelijk ingericht en een fijne manier om kortdurende 1 op 1 ondersteuning te kunnen vinden, iets wat in de praktijk op school niet mogelijk is.
