choosiness

About a woman's choosiness, the title is a euphemism for copulation.

But he displays the same choosiness in this area too: 'I find most of the things on television are pretty repetitive.

Darwin explained sexual selection as a combination of "female choosiness" and "direct competition between males".

His choosiness about where he squatted to defecate had grown to the point of compulsive obsession.

But once the female has demonstrated a liking for the male, he will start exerting his own choosiness by behaving extremely aggressively toward her.

In species where both sexes invest highly in parental care, mutual choosiness is expected to arise.

Females typically evolve greater abilities to discern the qualities of males, such as choosiness in mating.

For female mammals, with a relatively slow reproduction rate, sexual selection leads to choosiness, which helps females select higher quality mates.

The program involved players with two genetically determined traits, a 'cooperative trait' and a 'choosiness trait.'

The development of such cooperation requires variation in the degree of cooperation and choosiness, which the researchers attributed to genetic mutation and variation.

Ambiance Counts, Too In addition to price, many returning customers are displaying a new-found choosiness, demanding more in the way of merchandise and atmosphere, experts say.

Choosiness is all-important to "The Genius Factory," Mr. Plotz's book about the ultimate in consumer elitism, if not in satisfied customers.

A small Amazonian frog known as Physalaemus petersi provides a particularly strong example of how females' choosiness in mates may be driving the formation of a new species.

Since both sexes are ornamented, crested auklets align with Robert Trivers's parental investment theory, which predicts that with biparental care, mutual choosiness will arise.

Nick was momentarily bemused by the freaky choosiness of the tornado, which had taken most of the barn but had disdained their bikes, when he saw that Tom was weeping.

The technique would be useful not only to increase the number of potential hatchings, but also to create genetic crosses that can't be done "naturally" because of the choosiness of parrots.

Whether this is a result of male-male fighting or display, or of female choosiness differs depending on the species as the shape, size, and function of antlers vary between species.

Playing around with parameters by adding tail feathers, clipping tail feathers or painting them different patterns, Dr. Moller found that length and symmetry figured more or less equally in female choosiness.

At the core of the debate are assertions that are touchstones for evolutionary psychologists: that evolution favored promiscuity in men but choosiness in women and that the male of the species evolved to prefer young women because they are more likely to bear children.

Gavrilets also identifies the cost of female choosiness as a critical issue: many models of sympatric speciation depend on the assumption that females always succeed in mating even if the male type they prefer is rare, so their choosiness has no cost.
