The process of speciation is completed with the cessation of genetic exchange.

Islands are known to differ in the food supply available to ground finches, mainly seeds.

To summarize, the particular song a male sings, and the behavioral responses of females to song and morphological signals, are not genetically inherited in a fixed manner but are determined by learning early in life.

Evidence of epistasis from hybridization studies is more scarce.

Plumage features constitute a major component of courtship signals.

The theory of founder effects does not explain how novel features like plumage traits arise.

The process of speciation is completed with the cessation of genetic exchange.

Almost nothing is known from hybridization studies about the inheritance of courtship behavior of females, or of their responsiveness to particular male signals.

Males transmit signals in courtship through behavioral displays.

Thus mating of females was strictly along the lines of paternal song.

Species can be recognized by their morphological characteristics and songs.

Thus the genetic basis to the origin of bird species is to be sought in the inheritance of adult traits that are subject to natural and sexual selection.

We observe closely related species in sympatry and infer how they evolved from a common ancestor.

Genes that underlie the capacity to receive, use and transmit information are the evolving properties.

The divergence of songs in the new population away from those in the progenitor population would only be prevented if these processes were balanced by repeated immigration and subsequent breeding: song flow.

Closely related species of birds are also chromosomally similar.

Exchange of breeding individuals between two populations tends to homogenize their gene pools.

The independent role of morphology in mate choice is revealed by the rare instances where the usual association between song and morphology is disrupted.

Bowling is a sport for people who have talent to spare.

Clearly, the Obama presidency hasn't wiped out racial prejudices.

They've got this house style which is writer driven. I heard of one person who sent his script in, and Karen Berger said there weren't enough words in it. Put some more in.

Fear less, hope more; eat less, chew more; whine less, breath more; talk less, say more; hate less, love more; and all good things shall be yours.

I want to play an action hero. I'm ready for roles that totally aren't me.

You are the most beautiful bride there ever be. Dont let anyone else tell you otherwise.

I wanna live 'til I die, no more, no less.

There is no reason to continue to fail our girls.

I'm sort of one of those weird actors who whenever I do a play, I think, 'Oh, we should film this,' as opposed to have to belt it out of ourselves in a theater auditorium.

I love singing. I have spent as much of my life trying to improve my singing as I have practising guitar.

Gratitude is not only the greatest of virtues, but the parent of all others.

In retirement, every day is Boss Day and every day is Employee Appreciation Day.

The hand that gives is among the hand that takes. Money has no fatherland, financiers are without patriotism and without decency, their sole object is gain.

Dead men tell no tales.

Poetry is man's rebellion against being what he is.

Wives are around a lot longer than your sporting years.

Growing up in Georgia, I used to think people up north or out west were so different. They're really not. They're just regular people who live in small towns. They grow up and try to raise families and have a job and go to church and play softball. It's that way everywhere.

If you walk down the street and see someone in a box, you have a choice. That person is either the other and you're fearful of them, or that person is an extension of your family. And that makes you at home in that world and not fearful. So really it's very self-serving.

When you do a low budget movie, you get a little over-ambitious.

It no longer bothers me that I may be constantly searching for father figures; by this time, I have found several and dearly enjoyed knowing them all.

The country is stronger than the result of any one election. But we shouldn't forget that these are just ordinary people. I wish Americans would look at them level, not down or up - just level. It doesn't take some special dimension to be president.

I would also point out that many governments that chose not to support this war - certainly, the French president, Jacques Chirac, as I recall in April of last year, referred to Iraq's possession of WMD.

Wine and women do not go with song. Alcohol is the worst enemy of the imagination.

I honestly think that it automatically hurts me if I said that I supported the war in Iraq and I support the troops. That automatically kills me for getting a bunch of movies, a bunch of TV shows. People don't want to hear from me.
