What'd We Do Without Um?

No, not what'd we do without pregnant women, what'd we do without scientists:

WASHINGTON - Scientists think they have figured out why pregnant women don't lose their balance and topple over despite ever-growing weight up front.

Evolution provided them with slight differences from men in their lower backs and hip joints, allowing them to adjust their center of gravity, new research shows.

This elegant engineering is seen only in female humans and our immediate ancestors who walked on two feet, but not in chimps and apes, according to a study published in Thursday's journal Nature.

Never mind that any lumberjack, or goat herder, that ever lived with a pregnant woman could tell you why they don't fall over: the wobble like Weebles. It may be that the scientists thought we needed an answer to this question because no man in his right mind ever spoke of the wobbly way pregnant women walk. I'm only able to post this because I checked that there are no pregnant women within a half mile in any direction.

Oh, almost forgot, the reason I was amused in the first place: Below the picture, the "click to enlarge" button. Ha! I actually clicked it to see if she would get bigger.
