Anatolian Bump?

Scorpius I dont need a greedy friend like you
The bump means that I am a descendent of some old man with a beard, who fell on the back of his head, so he got a bump there, or it could also be that he was not liked by people so they hit him on the back of his head.

Originally posted by mamikon Halogroups do not mutate throughout the environment. If you had one son living in CA and another in Anatolia, they both of them would experience similar rates of mutations (the rate of which almost eqals 0). Unless of course the son in Anatolia is living in an environment with high levels of radiation or something...

Dude you are wrong , genes adopt to their environment , its called natural selection. And there is a lot difference between the environment of CA and Anatolia

Genes mutate randomly (through 'errors' in the dna copy process), and since only the successful mutations remain and dominate, it looks like the mutations are controlled by something, but they are not. Natural selection means just that; nature (the environment) "selects" the mutated species that adopt best to it.

Originally posted by Afsar Beghi Ok I can be wrong, i was not he best at biology. But what you say is that dna mutates randomly? And what causes the errors in the copy process then?

Nothing, it just happens, though not quite often of course
Unless there are special environmental conditions such as high radiation levels (as mamikon already mentioned)

Humans have one of the most precise DNA replication mechanisms,
nevertheless there is at least 1 mutation per 10^9 bases replicated
during mitosis or meiosis. As you are sitting and reading this
mutations occur in many of you cells, however, since you have two
alleles of the same "good" gene, if there is a random mutation, and one
of the nucleotides of the gene on one chromosome is changed so its
translational product is ineffetive, you still have another gene on the
other chromosome. It is very unlikely that mutation takes place
in the same cell, in the same locus, on the same gene, on the other
good chromosome. Thus we dont "feel" the effect of most of these
mutations.

However, since you are a guy, you are somewhat accursed with an only
one X chromosome and a useless Y chromosome. So my friend, a mutation
in your X chromosome will cost you dearly (one example is color
blindness; many males have, virtually no women do, since a gene
controlling color (and there are many of those) reside on the X
chromosome. So, I suggest you close this window (radiation) and enjoy
nature (dont forget sunblock).

does HIV realy come from chimps

Originally posted by Afsar Beghi I think DNA is not a way to research your ethnic origin, cause haplogroups mutate through environment. So if I was from CA and I had a son who went to Anatolia, then we had different haplogroups, cause its mutating and adapting to the environment all the time. Thats why it is hard to find a connection between the turkic people ( cause they migrated all the time).

Well, for precise info about the DNA test, please, check National Geographic and www.ftdna.com (there are some other nice sites as well). Shortly I can tell you that, Y chromosome is passed down from father to son. If son gets a mutation he will still have his father's dna-markers intact and then his own descendant will inherit the grandfathers markers plus his father's mutated ones and so on. So there can not be a mistake Y-DNA test, the matter is how you interpret them (i.e. occuring time and place etc.)

maybe, you'll think that I have lot of money, but I was doubtful as well :):) so I made two independent DNA-tests and both coincided exactly: in Haplogroup and in Haplotype. If you finally decide to make a DNA test, I'd advise 37 marker test at www.ftdna.com It's not cheap, but very precise.

One more note deep ancestry goes back to the time when there were no ethnicities in the modern sense. All modern ethnicities, even the isolated ones, are mixture of the descendants of 2 or several Haplogroups.

Actually I am somewhat curious myself. Also kardukhi, why did you decide to have the paternal test instead of maternal test (mtDNA).

What was your haplogroup?
