Human Males Evolve At a Faster Pace Than Females 454
Tisha_AH writes "A report by the Whitehead Institute indicates that the human Y chromosome present in males is evolving at a furious pace. Across the chromosome there can be as much as a 33% difference within humans alone. The portions of the chromosome evolving fastest are related to sperm production."

Very seriously, I had a feminist girlfriend that wouldn't believe a child sex was defined by the spermatozoid. According to her the female genitals were as much responsible for the sex of the child.
I guess this article explains everything, she needs more evolution in order to understand those advanced concepts ;-))

You're correct, males do tend to generate more sperm than females...

Well, yeah, it says men are evolving faster... specifically, the Y-chromosome, and more specifically, it's related to sperm production.
Will they develop enhanced regeneration and adamantium claws?
In short, your junk is evolving. Not necessarily anything else. That MIGHT not be considered a complementary thing, depending on how you feel about your particular junk.
I feel pretty good about my "junk" but don't refer to them as junk. I am pretty sure they are holy...why my fiancee says oh god all the time...

Possible reasons...
1) Sperm better resists the flood of estrogen chemicals and produces more babies.
2) Random chemicals in the environment are mutating the Y gene faster (so change is not coming from a benefit just a lot of random change)
3) Sperm lasts longer to evade birth control as long as possible.
Male sperm production is down by about 1/20th of what it used to be the last I read so there is a lot of pressure here.
4) Mutated sperm trying to develop laser beams to cut through condoms and diaphrams.

It is well known that soldering leads to burned fingertips.
Those who do not learn to overcome this, eventually develop permanent callouses on their fingers.
The callouses on the fingertips lead to less sensitive fingers.
Less sensitive fingers mean that the male cannot feel the nuances of a woman's reaction when he is...errr...stimulating her with his fingers.
The woman being 'pleasured' decides she does not want a crappy, insensitive lover for a lifelong mate.
Said solderer goes childless throughout his life.
It is harder for those that solder to reproduce.
Of course, the upside to this ridiculous notion is that only men that learn how to solder well, without burning themselves, go on to reproduce. Over a significantly long time period, therefore, a human population should get better at soldering. Take that football players! Ha!

Humans are not monogamous. Humans did not evolve as a monogamous species. Pairing may be beneficial to raising children, but humans have a long history of sleeping around.

In species where females usually mate with a single male during a breeding episode, penises tend to be small and uninteresting. In those where females mate with several males (whether by choice or by force), penises are typically larger, and come with fancy decorations such as grooves, nobbles, and spikes.
The nob on the human male penis was specifically designed to scoop out a rivals sperm and deposit seaman deep into the vagina at which point the penis becomes soft so as to not scoop out its own deposit.
