Mechanisms of Evolution
What are the 5 mechanisms of evolution?
Mutation, Non-random mating, Gene flow, Genetic drift, & Natural Selection.
What is evidence of evolution?
directly observable small-scale change, bio geographic distribution, comparative anatomy, the fossil record, classification, and genetics.
What is speciation?
The formation of new and distinct species in the course of evolution.
What is the Hardy-Weinberg equilibrium
the amounts of different alleles (different versions of a gene) in a population will stay the same from one generation to the next.
What is mutation?
It generates the genetic variation on which the evolutionary process depends.
What is the definition of evolution?
The change in the characteristics of a species over several generations and relies on the process of natural selection.
What's a simple definition for speciation?
Who founded the Hardy-Weinberg equilibrium?
An English mathematician. Godfrey Harold (G. H.) Hardy and the German physician Wilhelm Weinberg.
What is natural selection?
A mechanism of evolution where organisms are more adapted to their environment and more likely to survive and pass on genes that helped them survive.
Give an example of evolution.
Peppered moth, Darwin's finches, etc.
Give an example of animals that faced speciation.
The Central European black cap, Galapagos ground finch, etc.
Natural Selection, Mutation, Genetic drift, Gene flow, & Non-random mating.
What is non-random mating?
A mating system is when some individuals are more or less likely to mate with individuals of a particular genotype than with individuals of other genotypes.
What is the most evident proof of evolution?
Fossils
Who discovered speciation?
An ornithologist Ernst Mayr.
Give an example of the Hardy-Weinberg equilibrium.
The beak color of finches has a complete dominance relationship where black beaks are dominant over yellow beaks.
