How do Charels Darwin supports natrual selection and evoulution?

Question

how does he do it

Answer 1

He wrote a 500 page book, intended as a short abstract of his theory. You can read it below. But things have moved on a long way in the 150 years since, for example Darwin knew nothing of genetics.

But basically he started with the analogy of domestic animals, and how they can be changed with selective breeding. Then he went on to describe how much variety occurred within any species and how biologists at the time were finding it difficult to decide where some naturally occuring species or varieties stopped and others started. Then he talked about the struggle for existence - that many more individuals were born in any species than survived to breed themselves. And as many traits were hereditary, traits which aided in survival would be passed on more than those which didn't. Thus there would be change to the species over time, like among domesticated animals. Natural Selection.

He supported his theory with a lot of factual observations, like geographic distributions, what little was known from the fossil record at the time, embryology, and many biological observations like modifications, vestiges, and the sterility of hybrids of closely-related species (keeping new species separate). But he also came up with most of the possible criticisms of the theory and convincingly explained them away.

Answer 2

Evolution happens in a variety of ways. Here's a simple scenario.

All lifeforms posses slightly different traits. The ones with the better traits are more likey to survive to adulthood and have young. These young inherit the good traits, so they are more likely to survive and pass it on to *their* young. This creates differences in populations consisting of a single species. If an ecological event occurs that separates that population (preventing them from interbreeding), then you now have *two* populations in *two* different habitats. If the habitats are different, then the "good" traits will be different, too. For example, green scales are great if you're a lizard living in the forest. But if you live in the desert, things will see you and eat you. So, lets say you have two populations of lizards. At one time, they both lived in the forest. Then half the forest became desert and was cut off from the forest by a mountain or something. The green lizards born in the desert would be eaten by predators. But the ones with a little more brown in them would survive, passing "browness" on to their offspring. So then you've got brown lizards in the desert and green lizards in the forest. Over time, the traits of the two lizard populations change so much that they can't or won't interbreed. Maybe the mountain is in the way. Maybe they don't recognize each other. Maybe, if two of them did hook up, the young would be brown AND green, and thus unable to survive in the forest OR the desert. So those young wouldn't live long enough to have young, or pass on their traits. Over time, these two populations become SO different, that breeding is impossible. Even if you forced them to have sex, the chromosomes would be totally different. No young would result, or if it did, the young would be "sterile"--or unable to have babies of their own.

P.S.-->Yup, I'm a Christian.

Answer 3

Darwin provided the theory and a little evidence. Science has since provided much more evidence.

The breeding of cattle, dogs, fancy fish plants and a whole range of flora and fauna all follow the theory of evolution.

In some ways it could be argued that evolution is a natural process in almost anything. Take engineering. Car engines, aircraft engines, electricity generation are all growing far more efficient almost year on year. Computers become far more powerful with greater memory, are for more energy efficient and yet become cheaper year on year.

Answer 4

Initially he did it with a number of different South American Pacific Islands Finches. They all varied slightly and, as a scientist, Darwin asked "Why?" As he looked at a population statistics and wondered why certain finches had longer beaks, he developed a theory based on adaptation. If resources are low in one area, what is the relying factor of survival? If it is long beaks to get nectar in deep flowers, then one would expect long beaks to develop. It might be small talons, or wide heads. It all depends on whats reproductively successful aka what allows an individual to reproduce.

There are many books on it...read up.

Answer 5

with a bottle of tums.If you dont like the green ones you dont eat them.After a short while there will be more green ones.And if they bred we would have even more.

there is NO proof at all go answersingenesis.org or search for ken ham
there the best
