Regarding the chromosomes, currently the male Y chromosome is gradually diminishing and may some day disappear.

Pardon my ignorance but do not all sexually reproducing animals have a Y chromosome? Do you have some reference for the assertion that the human male Y chromosome is "gradually diminishing"?

Perhaps a pair was lost during the evolution from ape precurser to hominid precurser.

Yeah. "Perhaps." Or maybe the whole evolution thing is a crock.

Because they see the size of the X compared to the Y and assume the difference is because the Y is "gradually diminishing." It may be just a matter or shrinkage, a la George Costanza.

My bad, in the previous Comment I said X when I meant to say Y. Old age. ;-(
