It is extraordinary the extent to which Darwin's insights not only changed his contemporaries' view of the world but also continue to be a source of great intellectual stimulation for scientists and nonscientists alike.
We are embedded in a biological world and related to the organisms around us.
An argument often given for why Earth couldn't host another form of life is that once the life we know became established, it would have eliminated any competition through natural selection. But if another form of life were confined to its own niche, there would be little direct competition with regular life.
Ultimately we need to recognize that while humans continue to build urban landscapes, we share these spaces with others species.
We share deep admiration for evolution, a force of Nature that has led to the finest chemistry of all time, and to all living things on this planet.
No animal shall kill any other animal WITHOUT CAUSE.
In fact, humans have less variation genetically than chimpanzees.
There are no monotone "values" in biology.
The fast fish, not the big fish, eats the small fish.
To be sure, the dog is loyal. But why, on that account, should we take him as an example? He is loyal to man, not to other dogs.
Every species has come into existence coincident both in space and time with a pre-existing closely allied species.
There isn't a sharp line dividing humans from the rest of the animal kingdom. All the time, we find animals doing things that, in our arrogance, we thought were just human.
Fishes live in the sea, as men do a-land; the great ones eat up the little ones.
Beasts of like kind will spare those of kindred spots.
that while the world wasn't built for humans, we were built for the world.
I grew up with the biologists. I know how they think.
Nature's patterns sometimes reflect two intertwined features: fundamental physical laws and environmental influences. It's nature's version of nature versus nurture.
The laws of nature are structured so that we grow and change, and get to experience the full spectrum of biological existence.
Evolution is a tightly coupled dance, with life and the material environment as partners. From the dance emerges the entity Gaia.
Other species help children develop empathy.
if we don't always understand animals, they always understand us.
Fishes live in the sea, as men do on land: the great ones eat up the little ones.
It has become evident that the primary lesson of the study of evolution is that all evolution is coevolution: every organism is evolving in tandem with the organisms around it.
When we have relationships with animals, we often make up who they are.
In the present epoch of struggle between two worlds the two opposing and antagonistic trends penetrating the foundations of nearly all branches of biology are particularly sharply defined.
