External selection forces that make survival hard.
To get the fastest rate of evolution these forces should kill or disable 50% to 90% of the individuals in each generation before they are able to reproduce. But these forces should not kill so many as to make the species go extinct. In most cases these forces only kill or disable less than 10% of the individuals in each generation before they are able to reproduce.
What else can I help you with?
Natural selection causes changes in populations of organisms not individual organisms because?
differential reproductive success caused by genetic variation is necessary for the process of natural selection.
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
According to the theory of natural selection a species that lacks the variations necessary to adapt to a changing environment will most likely do what?
Go extinct.
What is the selective agent in natural selection?
They are the selective agent in natural selection ;)
Was it absolutely necessary for natural selection to take place?
Genetic change is necessary for natural selection to take place
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
Why is phenotype variation necessary for natural selection and sexual selection?
Phenotype variation is necessary for natural selection and sexual selection because it provides the raw material for evolution to act upon. Variation allows for individuals within a population to have different traits, which may offer advantages in survival, reproduction, or mate selection. Without phenotype variation, there would be no diversity for natural selection and sexual selection to operate on, thereby limiting the potential for adaptation and species diversification.
Natural selection causes changes in populations of organisms not individual organisms because?
differential reproductive success caused by genetic variation is necessary for the process of natural selection.
Mendel's conclusions is a necessary foundation for Darwin's theory of natural selection?
There are alternate versions of a gene.
How are the four principles of natural selection necessary for natural selection to occur?
The four principles of natural selection (variation, inheritance, differential reproduction, and adaptation) are necessary for natural selection to occur because they describe the process by which certain traits are passed on to future generations based on their ability to help individuals survive and reproduce in their environment. Variation provides the raw material for natural selection, inheritance ensures that beneficial traits can be passed down, differential reproduction leads to the accumulation of advantageous traits in a population, and adaptation allows organisms to better survive and thrive in their environment over time.
What is the name for the process in which the organisms best adapted to their environment survive?
Its NaTuRaL sElEcTiOn if you didn't know.
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
Why does cloning contradict the principles of natural selection?
Cloning contradicts natural selection because it creates identical copies of organisms, rather than allowing for genetic diversity and variation necessary for species to evolve and adapt to changing environments. Natural selection relies on genetic variation for the process of evolution to occur, which is limited in cloned organisms.
What is the prefix and suffix of natural selection?
The prefix of natural selection is "natural" and the suffix is "-tion".
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
