QuestionAnswer
A characteristic that helps an organism survive and reproduce in its environment. Adaption
A group of organisms that can mate with one another to produce fertile offspring. Species
The process by which populations accumulate inherited changes over time. Evolution
The solidified remains or imprints of once loving thing organisms Fossils
A historical sequence of life indicated by fossils found in layers if the Earth's crust. Fossil Record
The remnant of a once useful anatomical structure. Vestigial Structure
The breeding of organisms that have a certain desired trait Selective Breeding
A distinguished quality that can be passed from one generation to another. Trait
The process by which organisms with favorable traits survive and reproduce at a higher rate than organisms without favorable trait. Natural Selection
Natural Selection 4 Steps Overproduction, Genetic Variation, Struggle to Survive, Successful Reproduction.
Each species produce more offspring than will survive to maturity. Overproduction
Individuals in a population are slightly different from one another, each individual has trait that either increase or decrease their chances of survival. Genetic Variation
A natural environment does not have enough resources to support all of the individuals born, in addition some are killed by other organisms. Struggle To Survive
The key to natural selection, the individuals with better traits are more likely to survive and reproduce. Successful Reproduction
A change in a gene. Mutation
The process by which two population of the same species become so different that they can no longer interbreed. Speciation
What are the three steps of speciation. Separation, Adaptation, Division
When portion of the population becomes isolated (ex.newly formed canyons, mountain ranges and lakes) Seperation
Once separated the environment can change, the species begins to adapt to their environment. Adaption
Over hundreds of years the species can become so different they can no longer interbreed, even if the barrier is removed Division

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.
