How do humans affect genetic diversity within a population?
Through artificialselection, humans select desirable traits and breed individuals with the desired traits
This may result in phenotypes that would not otherwise exist in nature
Can lead to more or less genetic diversity
Convergent evolution
A process by which similar environmental conditions select for similar traits in different populations, or different species over time
How convergent evolution occurs
1. Similar selective pressures result in similar phenotypic adaptations
2. Environmental changes can lead to similar evolutionary changes across different populations or species due to similar selective pressures
Convergent evolution examples
Streamlined bodies in aquatic vertebrates like fish and mammals
Humans affect diversity within a population by breeding plants and animals, and selecting for desirable traits
Convergent evolution is a process by which similar environmental conditions select for similar traits in different populations or different species over time
