there are two different rates that evolution could occur at. the first kind is gradual, which is small changes over time. the other kind is fast and it occurs when there is a big change the environment.

The hypothesis that the evolution of different species occur at a slow constant rate is called?
Gradualism.
How are evolution and reprodution related?
the rate of reproduction controls the speed of evolution because slight changes occur in every new generation.
Does evolution occur faster in an organism that reproduces sexually or asexually?
Depends entirely on the rate of reproduction.
How do independent assortment crossing over and random fertilization affect the rate of evolution?
They will determine how the fertilization will occur. These can allow for some interesting changes to occur with the different plants.
What effect does generation time have on evolution rate?
A long generation time makes for a slow evolution rate, and a short generation time makes for a fast evolution rate.
What are three theories about the rate of evolution?
I am aware of the following notions regarding the rate of evolution:Gradualism, that the rate of evolution is more or less uniformly gradual.Punctuated equilibria, that evolution is gradual, but punctuated by rapid fluctuations in rate of progression.Saltationism, that new species can emerge instantaneously, from one generation to the next.Saltationism has, to a certain extent, been disproved as a pattern for evolution, along with gradualism, although saltational events may on occasion still occur, for instance in cases of polyploidy, chromosomal fusion, or radical changes in HOX genes.
What is the rate of evolution?
Evolution doesn't have a constant rate because it depends on environmental factors and reproduction frequency.
Does Evolution occur slowly?
yes.
Why are adaptations evidence of evolution?
Because adaptations are an observed effect of evolution. They could not happen if evolution did not occur.
What effect does generation time have on evolution?
A long generation time makes for a slow evolution rate, and a short generation time makes for a fast evolution rate.
How are organisms related to evolution?
Organisms are required for evolution to occur. Evolution is defined as something that happens when organisms reproduce.
Does evolution occur in individuals or in population?
Evolution occurs in population not in an individual.
