Biological evolution a change in the frequency of alleles in the gene pool of a population over time.
coevolution the influence of closely associated species on each other in their evolution.
Non random mating which individuals with similar genotypes and/or phenotypes mate with one another more frequently than what would be expected under a random mating pattern.
Embryology The science of the development of an embryo from the fertilization of the ovum to the fetus stage
Bottleneck effect is the genetic drift resulting from the reduction of a population, typically by a natural disaster, to such an extent that the surviving population is no longer genetically representative of the original population.
Speciation the evolutionary process by which new biological species arise.
Homologous Structures the existence of shared ancestry between a pair of structures, or genes, in different species. i.e. wings of bats and the arms of primates. Wikipedia
Divergent evolution process of two or more related species becoming more and more dissimilar.
Convergent evolution describes the independent evolution of similar features in species of different lineages.
Punctuated equilibrium proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called stasis.
Vestigial (of an organ or part of the body) degenerate, rudimentary, or atrophied, having become functionless in the course of evolution.
Analogous structures Body part in different species that is similar in function but not in structure that evolved in response to a similar environmental challenge.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
