by Ernst Mayr

I did not claim that speciation occurs only in founder populations.
- Ernst Mayr

Evolution thus is merely contingent on certain processes articulated by Darwin:
variation and selection.
- Ernst Mayr

Indeed, I was unable to find any evidence whatsoever
of the occurrence of a drastic evolutionary acceleration
and genetic reconstruction in widespread,
populous species.
- Ernst Mayr

Living in an entirely different physical as well as biotic environment,
such a population would have unique opportunities to
enter new niches and to select novel adaptive pathways.
- Ernst Mayr

 

New gene pools are generated in every generation,
and evolution takes place because the successful individuals
produced by these gene pools give rise to the next generation.
- Ernst Mayr

such as physiological, ecological, or behavioral innovations
that give these species improved competitive potential.
- Ernst Mayr

In those early years in New York when I was a stranger in a big city,
it was the companionship and later friendship which
I was offered in the Linnean Society that was the most
important thing in my life.

As a consequence, geneticists described evolution simply
as a change in gene frequencies in populations,
totally ignoring the fact that evolution consists of
the two simultaneous but quite separate phenomena of
adaptation and diversification.
- Ernst Mayr

The major novelty of my theory was its claim that the
most rapid evolutionary change does not occur in widespread,
populous species, as claimed by Most geneticists,
but in small founder populations.
- Ernst Mayr

people will forget what you did,
but people will never forget
how you made them feel.

And If I am compelled to take part in it,
Where is the director? I want to see him.
- Soren Kierkegaard

A leader is best when people barely know he exists,

they will say, "We did this ourselves."

I honor you, Hero, for you do not play to the crowd.
You play to your own soul.
An audience of one fills the house with its appreciation and applause.
Others follow you, and may attempt to emulate you,
but that is not why you are a hero.
Fame may smile upon you, or it may not.
The world may cheer your name, or you may be the unknown warrior
who rescued comrades in battle,
or taught a young girl how to shed tears of joy.
Whatever you did, you did not do for fame.
If you had, you would not be a Hero.
You are a Hero for your bold courageous inspired action.
- Jonathan Lockwood Huie

- Anonymous

Guilt says what did was not good;
... shame says I am no good.
- John Bradshaw

If a friend of mine gave a feast, and did not invite me to it,
I should not mind a bit.
but if a friend of mine had a sorrow
and refused to allow me to share it,
I should feel it most bitterly.
If he shut the doors of the house of mourning against me,

so that I might share in what I was entitled to share.
If he thought me unworthy, unfit to weep with him,
I should feel it as the most poignant humiliation.
