This is what strassman writes in his book. He can write anything he wants in whatever way he wants in any way he wants to support his theories. And you go and suck it.
Now, to the facts;
The pineal body starts forming on the 7th week of gestation. Not the 49th day. This is the difference, since we really do not know what exactly happens within the developing human embryo day by day. And even if we did, it'd make no much sense since different embryos develop their organs at different rates anyway. That is why we say "7th week" instead of, "day 45" or whatever. Strassman did a calculation 7 weeks = 42 days, ok lets' give it 7 days to make sure it's well formed = 49. Nice try.
Gender on the other hand comes by fertilisation, so lets' say "day 0". Speciation of the gamete factories aka ovaries and testes (if that's what Strassman calls "gender" ) also occurs on the 7th week. But so do hundreds of other structures. This is a very busy period in embryonic development. You cannot just take the pineal and the testes/ovaries out of context to imply whatever you try to imply.
So why does strassman draw this line between the ovaries/testes and the pineal? Even if ovaries/testes and the pineal were the only structures forming on the 7th week and, (just for the sake of argument) say that this is not a developmental coincidence, but there's something more into it, what does he mean?
Simple; he wants you to believe that your gender is what makes you human. And as the pineal forms the time the "gender" also forms, it must be magical since it is connected with your humanness. Go figure....
No, not at all. Stop taking Strassman's hypotheses as a fact, boy.
Nice one.
