What is genetic drift?
the ratio of allele in a population that changes randomly over time due to chance events, leading to variation in genetic traits.
What is an adaptation?
A trait that increases an organism's chances of survival and reproduction in its environment.
What is an example adaptation?
foxes and if the have bigger or smaller ears
How would these adaptations affect the ability to survive and reproduce in
a particular environment?
Larger ears may help dissipate heat in hot environments, while smaller ears may conserve heat in colder climates, impacting survival and reproductive success.
What is natural selection?
The process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.
What three things have to be true for natural selection to occur?
variation in population
variation passes down
variation affects survival and reproduction
compare genetic drift and natural selection
Genetic drift refers to random changes in allele frequencies in a population, while natural selection is the process where organisms with advantageous traits are more likely to survive and reproduce. Both are mechanisms of evolution but operate through different processes.
How do creationists and evolutionists differ in their views of natural selection?
Creationists typically reject the idea of natural selection as a mechanism for evolution, believing instead that species were created by a divine being. In contrast, evolutionists accept natural selection as a fundamental process that drives the evolution of species over time.
