So, genders have been around for hundreds of millions of years - why would anybody think that evolution would suddenly make them go away?
First of all, the subject is the disappearence of the Y chromosome, not of sexes. Second, there is evidence that the Y has been shrinking for hundreds of millions of years. These people have shown that the shrinkage more or less stopped about 25M years ago.
I think that the assumption is that those genes would move elsewhere and other mechanisms would develop to control differentiation. Other lifeforms manage it.
I think that the scientists understand that the disappearence of the Y chromosome does not mean the disappearence of men. The reporters, on the other hand...
The Y is not essential to sexual reproduction. There are mammals that have none: the males merely have a single X. Some plants have no sexual chromosomes at all. In some fish sex is controlled by temperature during development.
And the wonkiness of the comments is obviously an objective and reliable measure of the accuracy of the article. Just as it is on Slashdot, for example.
Now to stay the same weight as you, he'll have to eat several hundred calories per day less than you. Even if you both have exactly the same daily routine. His metabolism adapts to weight loss by slowing down and burning fewer calories. Not only that, appetite hormones react to significant weight loss by adjusting to levels normally associated with starvation.
After another 6 months or so he will be able to keep his weight matching yours by eating and exercising about the same as you. The adaptation goes both ways.
Certainly true for me. If I run my two miles in the late morning (finishing with a sprint) I find myself eating a light lunch without having to exert any self-discipline. I don't feel nauseated or anything: I'm just not as hungry.
It is absurd to drive for an hour to a gym to have 40 minutes of exercise there.
I haven't been to a gym in thirty years and I own no exercise machines. I run on the street and work out on the kitchen floor. The only weight I lift is myself.

The point of the article seems to be that the change is not ocurring.
Uh huh. And women will be reduced to just some ovaries and a uterus. Sure.

Don't anthropomorphize evolution. It doesn't like that.
Where did you get that ridiculous idea?
No FTL ever: it is a logical impossibilty. There was, however, hope of interesting new physics.
You do realize that "sufficient length" is on the order of a millimeter, don't you? (And might be much smaller.)
Do Apple printers have those features? If not why do you need them?
By being hired by a manager who also has a degree in journalism.
Union scale in the USA, of course. Do you think this is about human rights or something?

But only of "right-wing" claims, of course.
> ...I can't get back to work.
Why not? How does having your HR still decreasing from exercise stop you from working?
Yes. They'll all stop working then and it will become impossible to make any more.
> I no longer have an easy target to cut from the diet.
Alcohol. And snacks.

Do your part. Shorten yours.

You don't need to know that. Weigh yourself. If you are trying to lose weight and a week goes by during which you don't lose half a kilo eat less.

Shorter years. We're working on getting rid of the leap second: that'll help.
