Question | Answer |
The process by which individuals are better adapted to their enviorment and are more likely to survive and reproduces is called | Adaption |
Any difference between individuals of the same species | Variation |
The time it takes for half of the atoms in a sample to decay is its | Half life |
A well tested concept that explains a wide range of observations is a | Scientific theory |
The theory that species evolve quickly during short busts of time is | punctuated equalibria |
Documentation of the milions of fossils scientists have collected over time is called the | Fossil Record |
Unstable elements that decay or break down into different elements are | Radioactive elements |
Similar structures that related species have inherited from common ancestors are called | homogolous structures |
A hollow space left where the fossil has decayed or dissolved is called a | mold |
a process comparing the age of two fossils by their placement in the sedimentary rock is | relitive dating |
Gradual changes in a species over time is called | gradualism |
Fossils that are buried in sediments and actually changed into rock are | petrified fossils |
a trait that helps an organism survive and reproduce is an | adaption |
the theory that evolution occurs slowly but steadily is | gradualism |
A diagram that shows how scientists think different groups of organisms arerelated is a | branching tree |
preserved remais of an organism that lived in the past are | fossils |
a copy of the shape of the organism that made it is called a | cast |
thisa factor in natural selection as organisms attempt to survive using the same limited resources | competition |
Evidence that related species had a common ancestor because of the way their bodies are automatically constructed similar ways | homogolous structures |
This factor in Natural Selection happens when there are more offspring than can possibly survive on the given resource | overproduction |
A group of organisms that can mate together and create fertile offspring. | Species |
