Process
Evolution
The process by which living things change over generations through changes in their genomes.
Evolution Lab
Watch natural selection and genetic drift change how common a gene version is, in small and large populations side by side.
Step 7 of 8LabSimulation
How this step works
- Open the Evolution Lab and work through it at your own pace.
- Come back here and mark the lab as done.
Lab XP is earned once per lab. If another path includes the same lab, finishing it here counts there too.
Concepts you will meet
Process
Natural selection
Individuals better suited to their surroundings leave more offspring, so their inherited traits become more common. Darwin's finches and peppered moths are well-studied examples.
Process
Genetic drift
Random changes in how common alleles are from one generation to the next, strongest in small populations.
Idea or model
Allele
One of two or more versions of a DNA sequence at the same place in the genome. You inherit one from each parent.
Level of life
Population
All the members of one species living in the same area at the same time.
