QuestionAnswer
The process by which individuals are better adapted to their environment and are more likely to survive and reproduce is called? Natural selection
Any difference between individuals of the same species is a 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 observation is a Scientific theory
The theory that speices evolve quickly during short burst of time Punctuated equilibria
Documentation of the milions of fossils scientists have collected over time is called Fossil record
Unstable elements that decay or breakdown into different elements are Radioactive elements
Similar structures that related species have inherited from common ancestors are called Homologus structures
A hallow 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 layers of sedimentary rock layers Relative dating
Gradual changes in a species over time is called Evolution
Fossils that are buried in sediments and actually changed to rocks are Petrifed fossils
A trait that helps an organism survie and reproduce is a(n) Adaptation
The theory that evolution occurs slowly but steadly is Gradualism
A diagram thats shows how scientists think different groups of organisms are related is a Branching trees
A process that test the radioactive materials within a fossil to tell its actual age ( also knows as absolute dating)is called Radioactive dating
Preserved remains of an organism that lived in the past are Fossils
When no member of the species is still alive its called Extint
A copy of the shape of the organism that made is called a Cast
This is a factor in natural selection as organisms attempt to survive using the same limited resources(food, shelter, mates..) Competition
Evidence that related species had a common ancestor because of the way their bodies are anatomically constructed in similar ways Homolougus structure
This factor in natural selection happens when there are more offspring than can possibly survive on given resources Overpreduction
