Selective breeding takes awhile because a cows gestational period is 9 months and then they cannot breed right away.

How natural selection different from selective breeding?
selective breeding is basically the artificial version of natural selection natural selection is where those who adapt and survive pass there genes on to the next generation while the others die off removing the weak and adding the strong for a example. giraffes with longer necks will be able to reach the higher leaves on a tree in a famine than those with short necks and therefore they will survive and pass on the long neck gene and the short neck gene will die off selective breeding is where you get 2 particular specimens of the same species (preferably) with the same gene and breed them usually this is done for a particular trait that the breeder wants in the next generation example a long tail short hair and long face in dogs so they can be sold into a area that has a higher temperature or long hair short tail and short face for in colder environments this tecnique has been used since the dawn of man and is the reason we have so many breeds of cats and dogs

Why does selective breeding take so long?
Because you have to get just the right genes together. Since it is not so random, it is going to take a little longer.
How is selective breeding different from natural selectio?
In selective breeding the traits that the offspring inheirits is controlled by the person who is doing the breeding. For example if a chihuahua breeder is looking to make smaller dogs, they are gonna breed two small dogs with the hope that the puppies will inheirit their parents traits. Natural selection on the other hand is not controlled by humans. It is when offspring inheirit traits that make it more likely to survive. Organisms with certain traits are more likely to survive and reproduce. If there are some mice born, some in the litter are white and the others are brown. When these mice go to find food, the white mice are more easily seen by the keen eyes of an owl than the brown ones. Therefore the brown ones are more likely to reach reproductive age and producing mice. This continues in a cycle until the mice end up almost all being brown.
Time why does natural selection continue to work?
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
What are some objections to natural selection?
Natural selection does not respect the rights of the individual. If you care for the rights of the individual - your own, for instance - you should avoid being naturally selected against. Fortunately, humans have expanded their control over their environment to such a degree that natural selection no longer has the role in our development that it has for 'wild' life forms. This makes it somewhat easier for us to consider the phenomenon of natural selection from an objective stance.
Why does natural selection continue work over time?
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
Is there anything that disproves the Darwin theory?
It is no longer Darwin's theory as the theory has been modified and strengthened by much work over 150 years. Even in Darwin's time the answer would have been no. The theory of evolution by natural selection is as correct as our science can make it. There are no theories or even ideas in opposition to selective theory.
How does knowing about inheritance help farmers and food produce?
Farmers learned to be careful in choosing the plants and animals used for breeding. The breeding of plants or animals with desirable traits in order to produce more offspring with those traits is called selective breeding. Using selective breeding results in better crops.Some of the crops resists pests and diseases.Other crops are bigger,stay fresh longer, or taste better.
How does natural selection help make a species stronger?
it makes them better adapted to the environment so they will live longer and produce more offspring.
What are induviduals in natural selection that are able to survive longer and potentially leave more offspring than induviduals called?
for Plato users it's D.(:
Why heritable characeristic which helps an animal to live longer will generally tend to become more common in the population as a result of evolution by natural selection?
These are called adaptations.
