Question about charles darwin?

Question

what is natural selection? give some example please

Answer 1

Population control.....The natural way.

Survival of the Smartest.

Answer 2

Survival of the fittest is a small but important misquote of Darwin. The actual quotation is 'non survival of the least fit'. The difference is that specimens of species not properly equipped for survival will perish, while those who are fit go on to breed. This is not the same as the more aggressive misquote which implies that the less fit are somehow targeted, or that evolution happens quickly. It takes hundreds of years for a species to evolve into a different form because of the "least fit" thing.

Answer 3

okay, natural selection is where the fittest survives while the weaker dies.

e.g. if a mother bird had 5 baby birds, 1st 2nd 3rd baby bird would survive because they're the fittest, they always push to the front to get their mummy's food but the 4th and 5th are the smaller one who can't push to the front of the line so they get no / less food making the first 3 birds grow bigger and stronger and the smaller 2 birds far smaller and weaker and dying eventually.

Answer 4

The Galápagos finches provide an excellent example of this process.  Among the birds that ended up in arid environments, the ones with beaks better suited for eating cactus got more food.  As a result, they were in better condition to mate.  Similarly, those with beak shapes that were better suited to getting nectar from flowers or eating hard seeds in other environments were at an advantage there.  In a very real sense, nature selected the best adapted varieties to survive and to reproduce.  This process has come to be known as natural selection.

Answer 5

You are growing up and end.

Answer 6

Natural selection is the process by which favorable traits that are heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common. Natural selection acts on the phenotype, or the observable characteristics of an organism, such that individuals with favorable phenotypes are more likely to survive and reproduce than those with less favorable phenotypes. If these phenotypes have a genetic basis, then the genotype associated with the favorable phenotype will increase in frequency in the next generation. Over time, this process can result in adaptations that specialize organisms for particular ecological niches and may eventually result in the emergence of new species.

SURVIVAL OF THE FITTEST

Answer 7

read origins of species.

Answer 8

Survival of the fittest.  Each individual is different from its siblings in small ways and each therefore has different survivability.  Over many generations it is the individulas with higher survivability which survive to reproduce, therefore increasing the chance of there successful characteristics becoming more prominent.  This natural selection is responsible for all the characters of living things, including flight, spinal chord, fins, in fact there very existance is a resuly of natural selectioln.  Mutation also plays a large part. Most mutations result in death before the animal can reproduce.  Howev er, very rarely, a mutation can be b eneficial, and then it will be incorporated and passed on to the next generation.
