What do scientist think happens as populations change over time?
new species form.
How are speciation and microevolution different?
Evolution and speciation. ( microevolution is imprecise ) Alleles can change over time in a population of organisms without any great change in the phenotype or behavior of a species. Then, to keep it simple, a geographic barrier arises between portions of the population and they can no longer interbreed, Mutations happen in the separate populations and evolution can take two different paths now with natural selection driving the winnowing of variations so that adaptive change is happening in the immediate environment of the sundered populations. Given enough time the two populations gene pools will have such a variance in the alleles contained in those two gene pools that two different species will arise.
Where do new species come from?
Generally when a species splits into two populations that are separated by some means that keeps the now individual gen pools from intermingling. This allows new alleles to arise in the separate populations and as time passes this frequency changes in alleles can give rise to new species.
What is the process by which populations change over time?
What must be true for a characteristic to affect evolution?
Evolution is the change of allele frequency in a population of organisms. So, for a characteristic to affect evolution it must be heritable, genetically so, it must be selected for, or be the result of recombination processes and it must be in the germ line where it is passed to future generation of, hopefully, reproductively successful organisms who leave enough decedents to change the allele frequency in the populations gene pool over time.
What is a process in which populations gradually change over time?
Evolution i think
How did the plant populations in the community change over time?
by plants moving
Populations change over time due to the process of?
How can mutation affect evolution?
Mutation can serve up the raw variation that natural selection selects from, thus alleles are changed over time in populations of organisms; evolution.
What is evolution genetic terms?
Any change over time in the relative frequency of alleles in a population.
How does genetic data show change over time?
It shows how each generation's alleles have changed. :)
The theory of modern synthesis states that evolution involves changes in a population's?
