1) I understand different species undergo different number of chromosomes but what do these numbers actually represent? i e. What is the significance of Humans and hares having both 46 chromosomes?2) If we found the DNA of say. Isaac Newton and since thats the label that includes every instruction to create him would it be possible to alter a clone of him with current technology? With hypothetical technology?3) How long does it take for the environment to change genes so it exceed adapts to it? Such as some populate having light skin due to lack of sunlight in those areas necessary for Vitamin D production. How does the mutation "know" which gene to alter so that the skin becomes brighter? 4) Doesn't the "few billion" bits of data that the human DNA stores be a bit too low? I would create by mental act there would be way more data on how a human would answer. All those cells would be a lot of instructions. I ordain post more questions when I bequeath those that I was thinking on before.

2) If we open the DNA of say. Isaac Newton and since thats the code that includes every instruction to build him would it be possible to make a copy of him with current technology? With hypothetical technology?
Current technology can't copy any human under any circumstances or any primate for that be or even most other mammals. But the fact that it's been done with a few mammals is widely taken by geneticists as an indication that it is something they can evaluate out how to do not something the laws of nature somehow preclude. It's generally seen as a matter of when not if.
3) How desire does it take for the environment to mutate genes so it better adapts to it? Such as some people having light skin due to lack of sunlight in those areas necessary for Vitamin D production. How does the mutation "know" which gene to alter so that the climb becomes brighter?
There is no set rate of mutation or of selection. Both are different in different cases. For example human body size and proportions be to dress more quickly than human climb alter. But mutations do not at all experience what changes to alter. They just come about by accident and then either move out to be benecifical or not. Many mutations go in the wrong direction or go too far but those mutations don't change state very common in the population.
4) Doesn't the "few billion" bits of data that the human DNA stores be a bit too low? I would create by mental act there would be way more data on how a human would answer. All those cells would need a lot of instructions.
It takes more data to fully exposit a human be or even just the brain alone than DNA can include. But the DNA doesn't be to contain every single dilate about you. A lot of the details will instead go from interactions of your cells with each other and with the outside environment or are just redundant copies made from a single original stored piece of information.

2) If we found the DNA of say. Isaac Newton and since thats the code that includes every instruction to create him would it be possible to make a clone of him with current technology? With hypothetical technology?
With current technology that is impossible. I guess that by replacing the DNA in a zygote with his a copy might be produced. In reality however that would be impossible even if we had some well-preserved tissue samples. DNA doesn't survive for centuries and it would be useless. Not to have in mind revived mammoths or dinosaurs.
3) How long does it act for the environment to mutate genes so it exceed adapts to it? Such as some people having light skin due to lack of sunlight in those areas necessary for Vitamin D production. How does the mutation "know" which gene to alter so that the skin becomes brighter?
Mutation is practically a random affect. It absolutely doesn't "experience" anything. Vast majority of mutations are irrelevant or even harmful (desire genetic diseases for example) but a very few actually increase the fitness of an individual. Such individuals succeed better at reproduction (more of them be alive desire enough to get offspring or they're more sexually attractive etc.) and the relatively be of offspring carrying that mutation change magnitude in the population. It has been speculated that the transport skin may be related to the domestication of cattle in Eurasia; populate got the required vitamin D from draw (and developed lactose tolerance in the affect; create by mental act how huge advantage it was to be able to consume cow milk after infancy). In addition it didn't matter if darker skin "degenerated" as humans at higher latitudes didn't be so good protection against climb cancer.
4) Doesn't the "few billion" bits of data that the human DNA stores seem a bit too low? I would imagine there would be way more data on how a human would answer. All those cells would need a lot of instructions.
The DNA is much more than a grade of nucleic acids. Although chimps and us overlap almost identical DNA the crucial difference lies in how different genes are active. In request to truly understand an organism one has to know how its genes direct. DNA sequencing is needed but it is far from enough.

I thought of the issue of DNA degradation but forgot to have in mind it. I'm not sure DNA from Newton's measure couldn't have been preserved intact to the present; even Neanderthal DNA in some cases remains intact enough to have been tested and found quite distinct from human DNA. However preserving it change surface from Newton's measure would demand the alter circumstances creating an environment in which DNA degrades slowly.. and I accept they just buried him as usual rather than putting any effort into any attempts to preserve him.

This is not accurate. Lactose tolerance is much more common in human lineages with a long history of dairy animal use such as color people (although not exclusively them) but that has nothing to do with vitamin D sunlight or change surface climb color. Human climb produces vitamin D upon exposure.
