Evolution Intro

Notes that begin evolution

QuestionAnswer
process of descent with modification over time evolution
said that evolution was due to natural selection Charles Darwin
process where organisms become better suited for their environment adaptation
environmental factors determines who survives and reproduces natural selection
ability to survive and reproduce fitness
one gender (usually females) do the selecting sexual selection
humans control the breeding and determine the traits in other species artificial selection
separated by time temporal isolation
separated by physical barrier geographical isolation
genetic drift caused by few individuals leaving to start a new population founder effect
genetic drift where a disaster causes the reduction of alleles to only the survivors bottleneck effect
all of the alleles in a population gene pool
only traits that nature can act on heritable trait(s)
traits that environment cannot act on acquired/learned trait(s)
male and female reproductive parts do not allow for successful mating mechanical isolation
separated based on actions behavioral isolation
new species due to be geographically isolated allopatric speciation
new species despite being in the same area sympatric speciation
the creation of a new species speciation
describes a population that is stable and NOT evolving genetic equilibrium
having more offspring that can survive overproduction
structures with similar structure, but different function homologous structures
structures with similar functions, but different structure analogous structures
structures that have become reduced due to no longer being used in modern day species vestigial structures
the best (most accurate) evidence that species are related or share a common ancestor DNA and biochemistry
evolution where a species becomes more different divergent evolution
evolution where unrelated species become more similar convergent evolution
evolution of 2 species due to a close relationship between them co-evolution
most accurate dating of the age of fossils or rock layer using radioactive isotopes radiometric dating
less accurate dating of fossils or rocks layer age based on other fossils around it relative dating
type of fossil used to estimate the age of other fossils index fossils
theory that evolution has long periods of stability with brief period of many extinctions then quiet again punctuated equilibrium
theory that the rate of evolution is slow and steady gradualism
slow, but gradual loss of a species due to natural selection background extinction
they loss of many species in a short period of time due to a world-wide scale disaster (ex. meteor strike) mass extinction
succession after a disturbance that leaves no topsoil primary succession
succession after a disturbance that has a topsoil in place secondary succession
the final stage of succession where the community is stable climax community

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.
