What type of adaptation is the venom of a snake? | Functional |
What is the process by which the entire species gradualy changes over time? | Evolution |
What do we call the remains of once living organisms? | Fossils |
In what type of rock can fossils be found? | Sedimentary Rock |
When body parts of different organisms are similar in shape and function, we say these structures are? | Homologous |
When two organisms have homologous structures, we say they must have _____ from a common ancestor. | Evolved |
What theory states that organisms with better adaptations are better able to survive and reproduce? | Natural Selection |
What are the 4 key points of Natural Selection? | 1. Competition2. Survival of the Fittest3. Overproduction4. Variation |
What do we call differences in apppearance within a population? | Variations |
What are 2 causes vof ariations within with a species? | Sexual Reproduction & Mutations |
When a species make MORE organisms than will likely survive, it is called: | Overproduction |
When organisms from different species fight for similar resources, they are: | Competing |
When one organism is born with a more useful trait that helps it to get a resource and live, we call this: | Survival of the fittest |
Who developed the Theory of Natural Selection? | Charles Darwin |
What do we call the layers of sedimentary rocks that are filled with fossils from the past? | Fossil Record |
Where in the fossil record are the OLDEST fossils found? | Bottom |
Where in the fossil record are the NEWEST, most EVOLVED, fossils found? | Top |
If fossils are found within the same rock layer, we can assume they are about the ____ age. | Same |
If a species does not reproduce, they will become | Extinct |
What happens to a species if the individuals that make it up are NOT born with useful adaptations? | They Die (extinct) |
What are 4 peices of evidence of evolution? | 1. Fossils2. Fossil Record3. Homologous Bones4. Homologous Embryos |
A lasting impression, or hollow imprint of a once living organism is called a(n): | Mold Fossil |
When the entire organism has been preserved in tar, ice or sap, we call this a: | Body Fossil |
Bite marks, foot prints and animal poop are alll examples of: | Trace Fossils |
A fossil made out of minerals in the shape of a once living organism is a(n): | Cast Fossil |
What does "homologous" mean? | When 2 things look the SAME |
What is an embryo? | An unborn egg |
If 2 organisms share homologous bones or embryos, scientists beleive the 2 organisms also share a common: | ancestor (distant relative) |
