What best describes the theory of evolution?

Answer 1

A theory supported by evidence (apex)

Answer 2

It is the primary theory in Biology that states life on earth has changed over time due to inheritable changes in DNA. Different species originated in response to varying environmental conditions.

A scientific theory is based on an observable phenomena, like gravity. A theory is the result of a positive test result, and accumulated positive test results that creates the sound basis for how something occurs. If there is no positive test result, it remains an unsubstantiated idea, or hypothesis.

Evolution is the process of physical change, over an extended period of time, that has been slowly accumulating positive test results, to the point where it can now be declared as fact.

Evolution via natural selection, or simply "the theory of evolution," suggests that any imperfect replication scheme coupled with some selection function (in our case the natural environment) will ultimately result in modifications to species.

Answer 4

Modern evolutionary theories are still based off of Charles Darwin's theories of evolution published in 1859. They have yet been proven as scientifically inadequate or incorrect, nor have new, more plausible theories been created so Darwin's theories are still the basis for modern evolutionary science.

Answer 5

Every time a life form creates an offspring, the offspring is different from the parent. If the difference is beneficial to survival, the offspring is more likely to live long enough to procreate. If the difference decreases the likelihood of survival, the creature may not live long enough to mate. Most of the time, however, the change is minuscule and has no significant effect on the animal's survival. Evolution needs no outside influence to produce more efficient animals. In the Sahara desert, paleontologists have discovered one of the most complete fossil records that show how whales went from land mammals to ocean mammals. This record includes nostrils that migrate to the top of the head and become one and an inner ear that mutates to better hear under water. Whales also have a completely useless hip bone. Note also that all ocean mammals' tail fins move up and down rather than side-to-side like fish and while swimming their spines move exactly like four-legged land animals. Consider also human birth. It is more dangerous, more painful, and our children are born less developed than other animals not because women are cursed, but because our hips have changed to accommodate walking upright. Our children must come out underdeveloped if they want to come out at all because our females' birth canals are smaller. This problem is not likely to be rectified due to the fact that we have found unnatural ways to ensure the preservation of mother and child. Male pattern baldness is also likely the work of evolution because we have for thousands of years found unnatural ways to cover our scalps.

Answer 6

the answer is the idea that life on earth has changed over time due to hereditary changes in DNA
