a Darwin theory question about evolution here.... Darwin fan´s only... are you a Darwin fan ?

Question

among many of his findings there is one that really appeals to my logic which is that of the unique pigeons that are bred with other birds to create all kinds of beautifull different pigeons and how dogs and horses are cross bred to create all kinds of show dogs and horses e.c.t.e.c.t. and how they survive to breed again and again and again until finally we have a unique species (which is apparentley how humans became) something unique mated with something unique in africa 500,000 years ago and made us,(i will add links here soon for the dissbelievers). SO i wonder if we can do it again and evolve again into something more unique?. the most intelligent animals here today i can think of are dolphins, dogs, crocodiles, and whales (and many more, this is off of the top of my head) SO with todays technology with artificial insemination and gene cloning can we artificially breed with another highly sophistocated and intelligent animal to produce a very unique species again ? better than us?

Answer 1

I'm into Wallace these days.

Answer 2

You are talking about genetic alteration, not evolution.

Anyhow:
1) Not all eggs and sperm will fertilize from different species of animals. And even somehow some can fertilize, it is so unnatural that the offspring is sterile. In another word, you can try mix and match, but it will only be one generation, and no additional off-spring.

2) If you say, you try to cross breed some species that are more closely resemblance to human and hoping that it may produce something that can bear youngs. Remember we don't know what works and what may not work. We don't understand all the DNA and what are they for. There are tons of experiments to try and error. For high level animals, it will takes years to know if the intelligences level is better or worse than the species to start out with. Intelligent A mate with intelligent B not necessary to be something better than A and B.


IMHO, I think it may be more worth while to try to develope a much more powerful computer and write much better computer programs so that it will help improve the quality of life for human beings. With today's technology and advancement of technology, computer will go double the speed every 18 months. With that, we can definitely create a "specie" that will have "intelligent" and consitency of behaviour.

Create a robot that will help solve human's problem or compliment on the human's weakness.

I rather built a robot than to mess with real live animal experiement and try to be God.


BTW, I hope you are not one of the sick people who try to do their thing with other animals.

Answer 3

What you have described with pigeons and dogs is not Darwinian (goo-to-you) evolution but natural or man-assisted selection.
They are not the same at all.
Great Danes and Poodles have been bred from a dog ancestor and are related to all other kinds of dogs such as wolves, jackals, coyotes, etc. Each of these is a specialisation of the original 'dog' kind. Poodles have much less genetic information than their ancestors. You could not breed a wolf from a Poodle, but you could probably breed something like a poodle from wolves.
Animals do not breed outside of their created kinds. (A kind is broader than a species).
Some people are surprised that lions and tigers can interbreed (resulting in Ligers and Tions) and thus are the same 'kind' but different species.
Neo-Darwinian evolution postulates that genetic mutations are the mechanism by which one kind of animal changes into another. However mutations never add new information, are usually harmful, and are usually eradicated by Natural Selection.

The notion of evolution is thus fatally flawed by observational evidence, and logic.

Answer 4

You misunderstand the theory. Nothing says that a new species results by the mating of two unique species. It has to do with mutation.

Apart from that is the fact that the definition of a species is that it cannot successgully mate and produce viable offspring with a member of another species. Cross human and dolphin DNA and nothing will come of it because the difference in the chromosomes is too vast. The parts wouldn't match up, and the haploid cells would be unable to unite into a single functioning diploid cell.

Answer 5

First, different species (generally) do NOT cross breed (well known exceptions exist such as the tiger/lion which are fertile or the horse/donkey which are not fertile) with other species. Although the Nazis tried unsuccessfully to interbreed humans and gorillas, I am not aware of any primates that can crossbreed with other species. Thus I do no think it would work for technical reasons. Birds, horses, dogs, and cat varieties are bred WITHIN a species but they can still breed with other varieties within their own species. Selective breeding to produce a new species is very rare though it does occur from time to time (especially in agriculture).

Second, while you can always find a volunteer to do ANYTHING, moral reasons would prohibit such experiments from being conducted (the Nazis conducted forced studies on prisoners). More likely, humans will try to genetically modify themselves through molecular biology techniques. Such experiments were conducted in the mid-1990s to correct some genetic defects but poor experimental controls resulted in the death of at least one subject and additional problems in some of the other patients. It is still being studied in animals, but we are many (more than 10?) years from such therapy being commonly used.

Answer 6

uve got it wrong man evolution is all about mutation, like sometimes animals are born with mutations that may be beneficial and allow the animal to better survive, if it does it breeds and passes on the mutation. As for artificially breeding a super animal.. it just wouldnt work, you could get the 2 greatest dogs in the world and breed them but what would you have? just another dog, you cant just pick 2 different species of animals and splice them together, we havent got the technology

Answer 7

we are doing this with pets and produce-animals and plants all the time

the generations for something like a dolphin are quite long and so it would take many years to see any progress

you can certainly see the differences man has wrought in dogs (as you pointed out) but even more so in things like beef cattle that have a profit motive attached

there is a great science fiction series, the "Ringworld" series, in which one group of herbivore-descended beings figure out how to set up a "lottery" on the population controlled earth so that people who win the draw get to breed more. over time they are trying to breed lucky humans. it works. (they are also trying to tame-down another race that is very war-like by inciting them into wars that they can't win so the more diplomatic ones survive and breed the most warlike die

neat huh

Answer 8

well it takes millions of years to take effect and evolution amongst humans in my view aint really happening, well it is to a small extent, but largely governments and soceity seems to be anti-evolution in that they hinder it. Mainstream culture hmmm doesn't seem to be in step with evolution, could be wrong though. I think in a hundred years time when/ if ,mass media and life as we know it changes then we may get the first steps towards evolving different humans. although i'm no expert.

By the way you forgot pigs! In their natural habitat they are clever too, after apes and dolphins they are next in line.

Answer 9

Darwin believed all the life on earth evolved (developed gradually) over millions of years from a few common ancestors.

Answer 10

If you are a Darwin fan, you will also know he reversed his original theory on Man. Darwin also became a believer in a Higher Power that must have created man. So, your question is not relevant.

Answer 11

cool question! we might be able to cross breed a huiman with a dolphin and get an intelligent man who can sneeze out of the top of his head!
