Natural Selection Individuals with successful traits produce more offspring and are more likely to pass those traits on to the next generations
Homologous structures similar structures (like limbs)in species that share a common ancestor
Vestigial structures remnants of structures that were important at one time but have no clear function today
Artificial selection breeding domestic animals and plants to produce offspring with desired traits
Gene pool all the alleles of all the individuals of a given population
Microevolution small scale generation-to-generation change in the frequencies of alleles
Genetic Drift A change in the gene pool due to chance
Founder Effect Small population with a limited gene pool, genetic drift is more dramatic
Gene flow exchange of genes with another population
emigration genes exiting an area
immigration genes coming in to an area
fitness a measure of an individuals contribution to the gene pool of the next generation
Hardy-Weinberg Equilibrium When populations are not experiencing changes to their gene pools, they stop evolving for a period of time

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.
