| structures, characteristics, behaviors that help an organism to survive | adaptation |
| area or place an organism lives | habitat |
| the variety of life or an organism | diversity |
| waxy, thich, short leaves found in | dry, hot climates |
| long, thin, broad leaves are found in | temperate, warm climates |
| long ears on a rabbit are adaptations to | let off heat |
| organisms that share large number of characteristics | species |
| species can | mate & reproduce offspring |
| usually, organisms within a species are not | identical |
| differences within a species is called | variation |
| shape, size, and color are examples of | variations |
| variations show up in both | physical traits & genetic material |
| 2 members of a species contribute genetic material through | sexual reproduction |
| sexual reproduction results in | new genetic material |
| sexual reproduction is responsible for | variations within a species |
| the combination of gametes to create a | zygote |
| zygotes are | fertilized eggs |
| reproduction by copying of an individual's genetic material is called | asexual reproduction |
| Many species that reproduce asexually can also | reproduce sexually |
| asexually reproduced offspring | are identical to their parents |
| Charles Darwin traveled to the | Galapagos Islands |
| C. Darwin wrote the book | The Origin of Species in 1859 |
| Darwin claimed that species | gradually develop from previous ones |
| a species change over time | is evolution |
| an organism adapts to its environment will survive and reproduce is called | natural selection |
| natural selection affects the population | not an individual |
| natural selection is based on 4 conditions | overproduction, limited resorces, variation, variation advantages |
| a group of indiviuals of the same species is a | population |
| when an environment changes | the organism must adapt |
