Theory of Evolution 2?

Question

Ok I've asked this question before, but I am answering another question at the end of this.

For those who do not believe in it, disprove this to me one time. When man started out in Africa, he ate meat, and his blood type was O. His digestive system was strong and hard. He moved to the Middle East and such areas, where he ate grain. Making his digestive system softer, and Blood Type A. Then he moved on to Asia, where he ate Vegetables, making the digestive system even more soft. His blood type was B. If evolution was not real, how is this possible?


Someone in my last question asked me how man can change their blood type simply by moving their location. I did not say that. Evolution takes time, they moved, they had a different setting, ate different food, and over time their blood type changed.

Answer 1

If I may make a suggestion, stop referring to our species as "man", but try "humans" instead. It isn't just that it's a bit sexist to refer to the entire species by the male of the species, but using a *singular* word "man" to represent an entire population, makes evolution more difficult to understand.

For example, when you say that "he moved to the Middle East", this leaves the image that "he left Africa" ... i.e. that there were no humans left in Africa, which we both know is silly. It is the source of confusion by people who wonder "why are there still Africans?" (which, I am serious, somebody asked the other day), or "why are there still monkeys?" (which is asked every single day).

To answer your question, the issue of "blood types" is given too much importance ... as if blood typing is some sort of categorization of humans. The terms A, B, AB, and O, just refer to the presence or absence of two proteins in the blood (antigens A and B). There is nothing that mysterious about the presence or absence of these proteins ... two parents with A blood can still give birth to a child with B blood, or AB or O. It's not like a completely different "type" of human is born.

So the change in blood types probably has nothing to do with where the humans are located, or what kind of food they ate.

The only relevance is that a migration temporarily separates a small sub-population from the larger population ... which can allow one blood type to increase suddenly in percentage of that population.

Answer 2

I don't have to "disprove" it because you haven't produced any evidence to support it. Yes, we came from Africa.

However, blood type has nothing to do with diet. There's some evidence to suggest that the ABO blood system developed because of immune system responses, and that certain blood types are more resistant to certain types of diseases. (There's a correlation between blood type and tuberculosis, for instance). Even this is speculation; but at least it's SCIENTIFIC speculation.

Answer 3

Evolution is true, but the theory of blood type and diet is totally bogus. Native americans came to America from Asia, yet Navajo and Mayas have a majority of O blood type, and Peruvians are 100% O type. African American, descendent from Africans, have MORE B blood type in % of their population than American whites.

Answer 4

I get your question - but you still can't change the blood type you were born with...regardless of where you move and how long you stay. Immigrants who are born with type O - and move to another country still die with type O.

You are mixing a single person's DNA structure with evolution.
Even theorectically, it doesn't work that way.

Answer 5

In a scientific dialog, one makes a hypothesis based on the evidence, not one makes a hypothesis and tells other people to disprove it.

what is your evidence for this claim, and how do you reconcile it with a clear founder effect for type O in Western Europe?

In order to make a scientific claim-the one making it gives evidence, dear. I'm sorry to say that based on your not knowing that your credibility is low.

Answer 6

You are assuming modern man actually hails from Africa. There are more theories that they didn't than they did, so let us stop there. Two, there are more than just food intakes to consider. The main thing being the water source of everything and the surrounding minerals, if your theory is correct. That being said I find it hard to believe you don't have more important questions to ask, like, are asteroids going to destroy mankind.

Answer 7

Evolution didn't do it, God did
