EVOLUTION START

QuestionAnswer
having more offspring than the resources available can support overproduction
gradual genetic change over time evolution
selection based on difference in appearance between males and females (usually females choosing) sexual selection
different traits in a population variation
members of the same species in an area population
selection that favors one of the extreme traits directional selection
selection that favors both extreme traits disruptive selection
selection that only favors medium trait stabilizing selection
where nature chooses which individuals survive and reproduce natural selection
all of the genes/alleles in a population gene pool
favorable trait ; trait that helps organism better survive adaptation
evolution to become more similar convergent evolution
evolution to become more different divergent evolution
the evolution due to the close relationship between 2 species co-evolution
isolation based on time temporal isolation
measure of how well organism can survive and reproduce fitness
random change in gene frequency due to small population size genetic drift
effect where few individuals leave large population to start new population founder effect
effect where few survivors remain after disaster to rebuild population bottleneck effect
able to reproduce and have fertile offspring needed to be in same species (2)
said evolution is due to natural selection Charles Darwin
the movement of alleles in & out of population due to migration gene flow
random change in DNA mutation
isolation based on things that are done (dance, song, etc) behavioral isolation
isolation based on a physical barrier geographic isolation
the male and female reproductive parts are mis-matched mechanical isolation
reasons hybrid cannot reproduce dies early or sterile
speciation that happens due to geographic isolation allopatric speciation
speciation that happens while being in same place sympatric speciation
things that happen BEFORE zygote is fertilized (prevents mating) pre-zygotic isolation (barriers)
things that happen AFTER zygote is fertilized (prevents having more offspring) post-zygotic isolation (barriers)

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.
