He was the first person to use the word "evolution" to mean change over time.
Who is Charles Bonnet?
100
This rate of evolution happens slowly with little changes happening over long periods of time.
What is gradualism?
100
This is the process by which evolution happens where nature chooses which organisms survive long enough to reproduce.
What is natural selection?
100
These structures have a different function in separate species but look very similar due to the fact that they are inherited from a common ancestor.
What are homologous structures?
100
This is when once related populations evolve independently of one another, usually when they are geographically isolated.
What is divergent evolution?
200
This man determined that natural selection was the driving force behind evolution (and is called the "father of evolution").
Who is Charles Darwin?
200
This is an inbreeding population of organisms that can have healthy, FERTILE offspring.
What is a species?
200
This is a beneficial trait present in a population that would give those organisms an advantage in their environment.
What is an adaptation?
200
These are small, unused structures that show common ancestory when found in different species.
What are vestigial structures?
200
This occurs when different species of organisms evolve similarly because they live in similar niches (environments). Ex. all flying animals
What is convergent evolution?
300
This man was an economist that said population was kept in check by things like war and famines; he gave Darwin the idea that maybe this happened in nature as well.
Who was Thomas Malthus?
300
This is when humans choose beneficial variations in organisms to keep these good characteristics in their genes.
What is artificial selection?
300
This is a change in the DNA and one way that variation happens in a population.
What is a mutation?
300
This is the study of similarities in organisms before they are born.
What is embryology?
300
This evolution occurs when two populations of organisms live together for long periods of time and evolve matching adaptation.
What is coevolution?
400
This man had the first theory of evolution that included the Principle of Use and Disuse and the Inheritance of Acquired Characteristics?
Who was Jean Baptiste Lamarck?
400
This term refers to the changing of colors of organisms due to pollution in the environment.
What is industrial melanism?
400
This is a graphic depiction of divergent evolution.
What is a phylogenetic tree?
400
These structures have similar functions and show how organisms can evolve in similar ways when living in the same environment but are NOT inherited from a common ancestory.
What are analogous structures?
400
This specific kind of divergent evolution occurs when one individual species gives rise to many other species (ex. Darwin's finches).
What is adaptive radiation?
500
This geologist gave Darwin the long time frame he needed for evolution to occur by stating the Earth was MUCH older than the 6000 years that was commonly believed at this time.
Who was Charles Lyell?
500
This is a rate of evolution where there are long periods of stability mixed with short time frames of quick change.
What is punctuated equilibrium?
500
This process happens when the chromosomes of sexually reproducing organisms mix and create variation in a population.
What is recombination?
500
This is the study of living organisms around the world to show how those that live in similar kinds of niches evolve in similar ways (ex. all desert animals have similar adaptations that help them deal with hot temps and lack of water).
What is biogeography?
500
This is the hypothesis that life on Earth came about due to the random combination of non-living/inorganic substances.
