The Human Genome and evolution

[EternalOptimist]

I was reading a magazine article last week about the genome.
Apparently all of the known functions that create a human account for a small fraction of the dna, and no one knows what the rest is for. yet.

One of the working theories is that part of the unknown dna is used for enviromentaly driven evolution, which seems to go against the orthodox view on how evolution works.

for example, if enviromental evolution is true, a skinny guy who comes from a skinny line, then becomes a blacksmith, he could father boys with big muscly bodies.

interesting

It won't matter - with the use of IVF (& in particular the direct injection of the male sperm into the egg procedure) we are stopping those environmental factors affecting reproduction

I think the point is that the sperm you produce when you are pre-blacksmith, is different from that produced when you are a musclebound blacksmith. ie your environment has caused you to evolve

In evolutionary terms - only if those muscular racing tadpoles were more energetic little critters than their weedy counterparts -would they be more succesful in a home run.
You are removing that challenge with IVF & assuming that all tadpoles that are fired out of the cannon are created equal

I think this is possible.
Family I know, father worked in a factory that damaged his hearing. Children born before he worked in factory ok, thoes born after have hearing problems.

why do you mention IVF ?

interesting. almost spooky in a way.
It sort of opens up a whole new avenue of thinking

So if I have good day at the bookies and then knock up the wife I'm guaranteed a born winner.

Was the magazine called Lamarckism monthly?

Imagine how difficult it would be to code environmental factors into DNA. The DNA would have to understand itself, and if it got too clever might decide it best that the blacksmith's son were born a bacteria. 3 arms at the very least.

It's true.

First kid is white and pastey looking just lke I am. The second one conceived about the time the wife went to Greece with the girls has much darker skin and looks positively mediterranean.






(this isn't true of course.)
