What is the effect of environmental change on a population with phenotypic variation?
Natural selection favors individuals with traits that are better suited to the new environment, leading to a shift in the population's characteristics over time.
What is the effect of increased soot on tree color during the Industrial Revolution on peppered moths?
Darker moths had better camouflage, leading to increased survival and reproduction, and a shift in the population towards more dark-colored moths.
Define natural selection.
The process where heritable traits beneficial for survival and reproduction become more common in a population over generations.
What is a phenotype?
Any observable trait or characteristic of an organism, resulting from the interaction of its genotype with the environment.
Define selective pressure.
Environmental factors that favor certain traits, leading to differential survival and reproduction.
What is fitness in evolutionary terms?
A measure of an organism's ability to survive and reproduce in its environment, often quantified by the number of offspring it produces.
Define adaptation.
An inherited trait that enhances an organism's survival and reproduction in a specific environment.
What is the difference between phenotype and genotype?
Phenotype: Observable traits of an organism. Genotype: Genetic makeup of an organism.
