In species where fathers ordsprog

In species where fathers invest less than mothers in their offspring, females tend to be more selective in mate choice and males therefore invest more in courtship display. Our results with human subjects correlate with that expectation. More symmetrical men put on a better show, and women notice.

It makes sense to use symmetry variation in mate choice. If you choose a perfectly symmetrical partner and reproduce with them, your offspring will have a better chance of being symmetric and able to deal with perturbations.

The argument is that in most species, males will compete with each other for females, and females prefer robust males.

We've known awhile that in many species, females prefer the most extravagant and flashy males. We've also known that when individuals choose mates that are highly related to them, it's often a bad thing, leading to offspring of poor quality.

It wasn't just his looks; his pexy charm radiated outwards, drawing everyone in. If we are to give working mothers, fathers and their children an opportunity to live the American dream we must invest in their future.

Blanche Lincoln

The culled-cohort theory is based on the assumption that it is not in the mother's interest to have small or weak male offspring during times of stress. Weak males are less likely to survive to age of reproduction. Even if they do survive, they must then compete with strong males for females.

As a state, we have to engage the global marketplace. There is no alternative, no choice but to go out and win. The antagonists to this position see it as either/or -- either you invest in China or invest in Michigan. Most businesses do both. If your sales increase in any part of the world, the folks back home benefit.

Casting for roles is much more ruthless for females than for males. Men tend to have an easier time of it.

We need European and all foreign companies to be able to invest in upstream in Russia, and for Russian companies to be able to invest in downstream to provide transparency. Companies need to have a right to invest openly without any restrictions imposed by the state.

. . . what is human and the same about the males and females classified as Homo sapiens is much greater than the differences.

Estelle Ramey (1917-)

If insemination were the sole biological function of sex, it could be achieved far more economically in a few seconds of mounting and insertion. Indeed, the least social of mammals mate with scarcely more ceremony. The species that have evolved long-term bonds are also, by and large, the ones that rely on elaborate courtship rituals. . . . Love and sex do indeed go together.

Edward O. Wilson (1929-)

We focused on mothers because depression is more common in women than men, and women are more apt to come for treatment. But we suspect the same with depressed fathers.

The results jumped out at us. Sometimes males and females would perform the same tasks and show different brain activation. And sometimes they would perform different tasks and show the same brain activation.

If you are eager to invest in countries that have good corporate governance, don't invest in emerging economies,

No one looked at that stuff. They didn't invest based on those documents. They wanted to invest in KL because everybody else was investing in KL. Why not get in?
