populations
microevolution refers to small - scale changes occurring within a over relatively short periods.
genetic drift denotes random fluctuations in frequencies within a population.
darwins finches in the galápagos islands illustrate changes leading to the formation of distinct species.
natural selection hinges on variation, heritability, and differential success.
mutations serve as the ultimate source of genetic.
the bottleneck effect occurs when a catastrophic event drastically reduces a populations size, leading to a loss of diversity.
gene flow involves the transfer of genetic material between.
the icefish lacks hemoglobin in its blood, enabling survival in extreme cold.
non - random mating occurs when individuals choose mates based on specific.
the amish community in the united states represents a scenario of the effect.

Explanation:

• Microevolution occurs within populations.
• Genetic drift is about allele frequencies.
• Darwin's finches show macroevolutionary changes.
• Natural selection needs reproductive success.
• Mutations create genetic variation.
• Bottleneck effect reduces genetic diversity.
• Gene flow is between populations.
• Antarctic icefish has adaptations.
• Non - random mating is based on traits.
• Amish show founder effect.
