Plumage features constitute a major component of courtship signals.

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.

Plumage features constitute a major component of courtship signals.

Flattery in courtship is the highest insolence, for whilst it pretends to bestow on you more than you deserve, it is watching an opportunity to take from you what you really have.

Throughout our courtship, Kenny told me that he had proof that Saddam Hussein was a threat because he possessed weapons of mass destruction. I told him, 'You had me at weapons.'

There is too little courtship in the world.

Those Marriages generally abound most with Love and Constancy, that are preceded by a long Courtship.

Males transmit signals in courtship through behavioral displays.

This is courtship all the world over - the man all tongue; the woman all ears.

Courtship consists in a number of quiet attentions, not so pointed as to alarm, nor so vague as not to be understood.

Courtship is to marriage, as a very witty prologue to a very dull play.

The bedfellows politics made are never strange. It only seems that way to those who have not watched the courtship.

They dream in courtship, but in wedlock wake.

People in all walks of life, and especially business, do not want to experience the collapse of cities like New York along with global finance and economy in chaos, but this is what business faces if we continue to attribute climate change to fossil fuels alone.

Technology is permeating every single thing we do... And to the extent that we can better expose our young people to all the different ways that technology can be used, not just for video games or toys, we're planning for the future.

It's funny, as a little kid, you look up to those guys who you play as in 'Madden,' and now to see myself in the game, it's an honor.

I never listened to the Grateful Dead as a teen; the only exposure I got was what came through the walls when my sister was listening to them.

I chose biochemistry as my major and graduated after 4 years with an Honours degree in Biochemistry. During that time, I had come to love biochemistry research, although I was just getting my feet wet in laboratory research.

You have to know how to evolve with age without trying to hang on to your younger image of yourself from the past.

What I've learned is that people have a desire to talk after the first line of reporters go away, and they are no longer speaking out of shock.

The writer wants to be understood much more than he wants to be respected or praised or even loved. And that perhaps, is what makes him different from others.

I don't think that writers have any responsibility to be good neighbors to the audience.

I feel liberated, empowered, inspired and motivated. Fear holds you back from achieving what you want in life.

In my own work, I don't have favorite characters, but I have characters that I relate to the most. And I relate the most to Simon from 'The Mortal Instruments,' and also Tessa from 'The Infernal Devices.' They're more sort of bookish and shy characters.

Neither of my parents would ever stand in the way of any of their children speaking their minds.

Myspace alone has just over 80 million users and ranks as the sixth most popular English language website and the eighth most popular site in the world.

I don't know. Only God knows where the story ends for me, but I know where the story begins. It's up to us to choose, whether we win or lose and I choose to win.

And as a Member of this body, I believe firmly that States do have rights, and I believe that local communities have rights, and they have made decisions to allow these businesses to prosper as they are a big part of their economy.
