They must help the organism in it'senvironmentso it may survive andreproduceand pass the trait down. If the trait is undesirable or useless the trait is selected against. Like if the desert was covered in snow, and all the 'prey' animals were out and wondering around. They can see if a 'predator' is coming, because of their orange-light brown color cause it doesn't blend in with the surrounding it isn't goodcamouflage.

What are the pressures of natural selection?
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
How did Lamarck's ideas differ from Darwin's?
Lamarck believed an individual organism acquired traits during its lifetime and passed those traits on to its offspring. He lacked support for his ideas. Darwin documented how inherited traits could be passed on by natural selection, that adaptations that give an organism an advantage is passed on through subsequent generations and becomes more common. He had evidence for his ideas (finches, tortoises…).
Is inheritance a requirement for natural selection?
Yes it does. Without variance in the organisms genome, that gives variance to the phenotype, there would be nothing for natural selection to select from.
How does natural selection affect variation?
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.
What role do alleles play in natural selection?
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
What are some natural selection for deer?
Natural selection will see to it that genes from the strongest and more fertile bucks and does are passed down susequent generations.

How would any changes in a mammal be passed on from generation to generation?
Through DNA, Genetics and Natural Selection.
Explain the difference between artificial and natural selection?
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
Why is natural selection the process responsible for evolution?
Well, it's part of the weakest link theory. Natural selection weeds out those who are not fit to carry on their genes. Only the best genes are passed onto further generations, leading to a more widely developed population.
What must be true of traits that are passed down through generations?
Traits that are passed down through the generations must be either culturally or environmentally inculcated or genetically inherited (or some combination of these). Evolutionary biology concerns itself with genetically inherited traits. In the long term, for genetically inherited traits to continue to be passed down through the generations, they must be at least neutral with regard to reproductive fitness, or advantageous (i.e. they must not be subject to negative selection pressure)

Why are stronger traits passed down to offspring?
So that the offspring have a better chance of survival. these traits are often chosen through natural selection.
How does natural selection enhance or reduce the variability of a species?
Natural selection doesn't reduce variation. Variation is regulated by the rate of mutation.Natural selection reduces the chance of bad variation from being passed on and increases the chances for good variation to be passed on.
What kind of behaviors do organism inherit from their parents?
Organisms inherit instincts from their parents. Instincts are natural behaviors that are passed down through generations as opposed to learned behaviors.
Why is Evan so hot?
it is a genetic gene that is passed on through generations
Can pediatric arthritis be passed down through generations?
I have heard of juvenile arthritis which is one or another form of arthritis that afflicts children under 16. and yes there is a tendency for these diseases to be passed on through generations.
