Transcript

It's a question that has plaqued humankind's deepest philosophical thinkers ever since men were men and women were women. Why are men and women really so different? Women have an XX pairing of sex chromosones, and men, a XY pairing. The sex of our ancestors was then determined not by sex chromosones, but by the temperature of the embryo at a developmental stage before birth. The Y chromosone progressively mutated, so much so that much of it no longer exists. But does this mean that as evolution takes it course, the ever-shrinking Y will spell the death of the male?
