Today SCIENTISTs Explain natural selection in terms of changes in?
genes
What are the criteria of success in terms of evolution by natural selection?
The fitness of a variant is expressed in terms of the average number of offspring.
The prevalence of genetically predisposed traits that have a reproductive advantage is best explained in terms of?
Natural selection
Why did Darwin's theory of natural selection challenge the ideas of the church?
Answer 1Many churches of the time posited that god created all the organisms of earth at one time, so that no organism was related except to vary from it's created kind. Darwin showed that through the process of natural selection new species were constantly arising from related organisms.Answer 2Theism rationalizes its beliefs in deities by pointing to the organized nature of nature, claiming that such complexities could not have come about through unguided natural processes. Darwin, with his theory of natural selection, provided just that: an explanation for natural complexities in terms of unguided processes. Basically, while Darwin's theory does not claim that no gods are involved in nature, it did away with the need for any gods to explain the diversity of life.
How does variation work to help cause evolution?
You have to have variation in order to be able to have more successful variations, which succeed in evolutionary terms, and less successful variations which fail. If there were no variation in a species, there would be no natural selection.
Is natural selection same as survival of the fittest?
According to evolutionary theory, natural selection is the principle that directs evolution.
Today SCIENTISTs Explain natural selection in terms of changes in?
genes
Which cells are influenced by natural selection?
In one way or another, all of them. However, we generally don't speak of natural selection in terms of how it affects cells (except perhaps germline cells), but in terms of how it affects populations, lineages or allele frequencies in gene pools. In population genetics, cells are merely the containers for collections of genes, and the machines that express those genes.
What are the criteria of success in terms of evolution by natural selection?
The fitness of a variant is expressed in terms of the average number of offspring.
What is another terms for survival of the fittest?
Natural selection. A much more accurate term.
The prevalence of genetically predisposed traits that have a reproductive advantage is best explained in terms of?
Natural selection
How was Darwin's theory tranalated into a theory about economic success?
It wasn't! The theory of evolution by natural selection has nothing to do with social Darwinism and to posit such a connection is ill posed. The theory of evolution by natural selection is about individual selection of organisms and has nothing to do with group to group success in economic terms.
What is Darwinian?
Darwinian evolution is descent with modification and natural selection, or, in other terms, reproductive variation and differential reproductive success.
How did Darwin explain the patterns of distribution of plants and animals?
He explained them in terms of descent with modification, common descent and natural selection.
What terms describes natural selection that acts against intermediate forms of a polygenic trait to increase genetic variation while not changing the average value of a trait within?
Disruptive selection
What is Darwinian evolution?
Darwinian evolution is descent with modification and natural selection, or, in other terms, reproductive variation and differential reproductive success.
What term is defined as the tendency of somebody member of a population to be better able to survive and reproduce and pass in their charaeristics?
Natural selection.
