Why Sexes?

Speculation Why 
the Sexes Exist

  • storkThe Y chromosomes is the section of the genome with the biggest variation .  There appears to be 4.8 times variation than in other chromosomes.  Also the one in humans is completely different from the one in Chimpanzees.

  • Although most mammals have Y chromosomes in fact it's the female that has the Y chromosome.

  • My postulate is the Y chromosome in male mammals and in female fruit flies is where new genes are constructed and tried out.  There is no X chromosome to back it up, if the gene proves defective so defective ones are rapidly lost to survival of the fittest if that's true.

  • Successful genes I propose are moved to the X chromosome.  There, they may continues to mutate but at a lower rate.  Now defectiveness produced by a single point mutation is not exposed 1/2 of the time because of the good copy on a female organism (or I guess a male one in fruit flies).

  • For a mechanism which might measure effectiveness of a gene is longevity and genes in the Y chromosome might move from one end to another.  Once they reach the other end, "the finish line", they might be moved to the X chromosome, with a similar process on the X chromosome.

  • So I propose that all animals are trying to innovate.  That is the species is trying to improve itself continually, perhaps in order to take a greater proportion of resources and have greater numbers or if survival of the sweetest is true, maybe they are trying to innovate in their genome, in order to do a better job of serving
