The name of the scientist who first published a book explaining evolution, and provided evidence of how it occurred.
Who is Charles Darwin
100
These are the natural differences among a species, that must exist for natural selection to occur.
What are variations
100
This is the basic definition of evolution.
What is "change over time"
100
Fossils (or preserved remnants of dead organisms) are only found in this type of rock.
What is sedimentary
100
This is a natural variation that helps an organism survive in its environment. Ex: Ducks having webbed feet
What is an adaptation
200
The name of the scientist who believed in the inheritance of acquired characteristics, or that giraffes grew long necks as a result of straining their necks all their lives.
What is Lamarck
200
This is one way variations/ evolution can occur.
What are mutations and environmental change?
200
This is the mechanism of evolution in which the better adapted organisms survive to reproduce and pass their traits on to their offspring from generation to generation.
What is Natural Selection
200
This is the molecular biology that all life has in common, and is the most compelling evidence of evolution.
What is DNA (and RNA)
200
These are the body parts of different organisms that function differently, but have similar bones.
What are homologous structures
300
Used x-ray diffraction to take the first photo of DNA.
Who is Rosalind Franklin
300
The slang term used to summarize natural selection, which results from a variation+struggle to survive+competition.
What is survival of the fittest
300
The main idea behind evolution, that all species evolved from...
What is a common ancestor
300
occurs when small samples of a population settles apart from the population
genetic drift, or founder's effect
300
These are structures of different organisms that tend to look similar because they serve similar functions, although their bone structures are different.
What are analogous structures
400
This is the Father of Genetics
Who is Gregor Mendel?
400
When organisms try to get their fair share of a limited amount of resources.
What is competition
400
Refers to smaller scale evolutionary changes within a species; can be seen in a lifetime
What is microevolution?
400
- structures having different mature forms but develop from a common ancestor
homologous structure
400
An explanation of events in the natural world based on observations. Unlike a scientific law, this can be falsified or changed as our knowledge of the subject matter changes.
