Tutoring biology, terms about evolution come up. The tutor mentions convergent evolution. Convergent evolution is the process in which species that aren’t related, nor similar, develop corresponding facilities. An example often given is flying: honeybees and hummingbirds can both fly, …
Tutoring biology, ideas about evolution arise. The tutor mentions punctuated equilibrium. Punctuated equilibrium suggests that, during the process of evolution, a species might remain relatively unchanged for a long period (the equilibrium), then suddenly undergo a period of rapid change …

Tutoring biology, mechanisms of evolution arise. The tutor mentions genetic drift. Genetic drift is a change of genetic ratios in a population – for example, the percent of individuals who have brown eyes vs blue. Importantly, genetic drift occurs by …
Tutoring biology, evolutionary concepts arise. The tutor mentions adaptive radiation. Adaptive radiation is likely one of the best-loved ideas relating to evolution. It starts with an original, single species that has a number of niches available. The concept is that …
Tutoring biology, biogeography comes up. The tutor mentions its connection with evolution. In biogeography, biologists observe and theorize about where species are found and why. For instance, the fact that kangaroos are only found in Australasia is a question for …
