the Y chromosome has degenerated rapidly, leaving females with two perfectly normal X chromosomes, but males with an X and a shrivelled Y. If the same rate of degeneration continues, the Y chromosome has just 4.6m years left before it disappears completely.

..... Agreed..........................Ha ha, or even a thousand years. and even viable in a soup of past nuclear war fallouts. Areas will be uninhabitable for millennia.

And just what makes you think that humans will still be around in 4.6 million years?
For example, a recent Danish study, published in PLoS Genetics, sequenced portions of the Y chromosome from 62 different men and found that it is prone to large scale structural rearrangements allowing “gene amplification” – the acquisition of multiple copies of genes that promote healthy sperm function and mitigate gene loss.
The study also showed that the Y chromosome has developed unusual structures called “palindromes” (DNA sequences that read the same forwards as backwards – like the word “kayak”), which protect it from further degradation. They recorded a high rate of “gene conversion events” within the palindromic sequences on the Y chromosome – this is basically a “copy and paste” process that allows damaged genes to be repaired using an undamaged back-up copy as a template.

It won't matter at that point because we'll all be immortal brains in robot bodies.

ATS scholars will likely resurrect this message and work the issue and fix the problem.
Preserve this message for millions of years into the future, so future ATS readers can remedy the situation before it becomes out of control. Thank you.

Hi ManBehindTheMask,
Yes, indeed.
Hopefully ATS webmasters will establish archives
deep underground to be retrieved by whatever species replaces
us then.
I forgot to mention that (oh, I hate to post this)
... that Y chromosomes from ET (done during alien abductions)
may be more robust and last longer.
YES! I totally agree with you and would hope AND pray the Webmasters also comb through and select my many witty and inspirational responses from the various forums I've visited to spur on and help encourage these future ATS scholars!
