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.

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

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.

We're all like children. We may think we grow up, but to me, being grown up is death, stopping thinking, trying to find out things, going on learning.

Let schoolmasters puzzle their brain, With grammar, and nonsense, and learning, Good liquor, I stoutly maintain, Gives genius a better discerning.

Without feeling abashed by my ignorance, I confess that I am absolutely unable to say. In the absence of an appearance of learning, my answer has at least one merit, that of perfect sincerity.

Learning teacheth more in one year than experience in twenty.

And I believe that the best learning process of any kind of craft is just to look at the work of others.

Concerning culture as a process, one would say that it means learning a great many things and then forgetting them; and the forgetting is as necessary as the learning.

And I like asking questions, to keep learning; people with big egos might not want to look unsure.

The lopsided attitudes of college professors pose a serious challenge to learning because students are so susceptible to becoming lopsided sheep.

I've never stopped learning.

I know what I like when I see it, but no way have I ever become interested in learning about it.

Not being a comic book fan, being thrown into that and seeing the extreme - it's taken very seriously. So I tried to do as much learning as I could about it so I wasn't mean or anything.

I spent a lot of years just learning my craft and falling down in front of the camera.

I'm learning English at the moment. I can say 'Big Ben', 'Hello Rodney', 'Tower Bridge' and 'Loo'.

Learning is the beginning of wealth. Learning is the beginning of health. Learning is the beginning of spirituality. Searching and learning is where the miracle process all begins.

I love talking about women because they are a constant study and you're always learning.

The experience of learning how to get straight to the core of a problem proved to be of immense value later when I had a long succession of responsibilities in large, complex government departments.

I think that obstacles lead to growth and ultimately, the most learning I've done in my life is between jobs.

I view life as a learning experience. It is not so much all about music; it is about what happens when you are doing the music.

I like doing accents and I like learning as much as I can learn.

In any of the arts, you never stop learning.

I have never forgotten my days as an Eagle Scout. I didn't know it at the time, but what really came out of my Scouting was learning how to lead and serve the community. It has come in handy in my career in government.

You have to study your field and you have to find out how other people do it, and you have to keep working and learning and practicing and ultimately, you would be able to do it.

Never make your home in a place. Make a home for yourself inside your own head. You'll find what you need to furnish it - memory, friends you can trust, love of learning, and other such things. That way it will go with you wherever you journey.

There are no secrets to success. It is the result of preparation, hard work, and learning from failure.

Human beings are accustomed to think of intellect as the power of having and controlling ideas and of ability to learn as synonymous with ability to have ideas. But learning by having ideas is really one of the rare and isolated events in nature.

I think the biggest difficulty is that when I'm here in America, there's a necessity of using English, so I really have a great sense of really wanting to learn, but unfortunately when I head back to Japan, the necessity vanishes and so does my enthusiasm about learning.

The rare person is still interested in new advances when they are adults. There is possibly a correlation with intelligence. In any case, you have to be fairly bright to keep learning and changing attitudes as you get older.

Only the other world has substance and reality; only good deeds and holy learning have tangible worth.

I loved education, and, yes, I did want to go on learning.

Making a wrong decision is understandable. Refusing to search continually for learning is not.

Women have to harness their power - its absolutely true. It's just learning not to take the first no. And if you can't go straight ahead, you go around the corner.
