An Evolutionary Perspective of Weakening of Y Chromosomes through Male Attitude to Females Introduction The Y chromosome the marker defining masculinity is shrinking steadily. Having lost thousands of genes over millions of years, probably it will vanish someday, a prospect raising debates about how this may eventually affect males' physicals and behavior. Testosterone, a hormone under the control of male gonads, testes, is integral to all those traits considered by convention to be masculine and thus encompassing physical strength, competitiveness, and dominance. Weakened Y chromosome strength invites speculation about its influence on testosterone levels and how it may shape male behavior and roles in society as well as fitness in evolution. The weakening Y chromosome, testosterone, and male social behavior are related through the aspect of genetics, evolution and societal tendency. Weakening Y chromosome: This sex determinant has lost genetic material over millions of years. Oth...
