As a species we are always hungry for new knowledge.
Chaim Potok

As I like to say, the entire collective memory of the species - that means all known and recorded information - is going to be just a few keystrokes away in a matter of years.
Dee Hock

As much horror as we have always created, we are a species that keeps moving forward, seeing new sights in new ways, and enjoying the journey.
Martha Beck

Biologically the species is the accumulation of the experiments of all its successful individuals since the beginning.
H. G. Wells

But it really wasn't until three to four years later, when we had an opportunity in the lab to make very detailed observations, and comparisons with other fossil discoveries, that we realized she was a new species of human ancestor.
Donald Johanson

But the truth is that Homo sapiens is a sensual species. I think all species are, to one degree or another.
Jock Sturges

Certainly it is wrong to be cruel to animals and the destruction of a whole species can be a great evil. The capacity for feelings of pleasure and pain and for the form of life of which animals are capable clearly impose duties of compassion and humanity in their case.
John Rawls

Certainly paleontologists have found samples of an extremely small fraction, only, of the earth's extinct species, and even for groups that are most readily preserved and found as fossils they can never expect to find more than a fraction.
George G. Simpson

Closely related species of birds are also chromosomally similar.
Peter R. Grant

Concord, solidarity, and mutual help are the most important means of enabling animal species to survive.
Christian Lous Lange

Crime is a fact of the human species, a fact of that species alone, but it is above all the secret aspect, impenetrable and hidden. Crime hides, and by far the most terrifying things are those which elude us.
Georges Bataille

Deconstructing the concept of race not only conflicts with people's tendency to classify and build family histories according to common descent but also ignores the work of biologists studying non-human species.
J. Philippe Rushton

Each simian had a much different body suit, so besides trying to define class across species, there was a definite attempt to dress each group in different styles.
Colleen Atwood

Eurasia ended up with the most domesticated animal species in part because it's the world's largest land mass and offered the most wild species to begin with.
Jared Diamond

Every paleontologist knows that most new species, genera, and families, and that nearly all categories above the level of family appear in the record suddenly and are not led up to by known, gradual, completely continuous transitional sequences.
George G. Simpson

First I shall name the eagle, of which there are three species: the great grey eagle is the largest, of great strength and high flight; he chiefly preys on fawns and other young quadrupeds.
William Bartram

For a solitary animal egoism is a virtue that tends to preserve and improve the species: in any kind of community it becomes a destructive vice.
Erwin Schrodinger

For most of the history of our species we were helpless to understand how nature works. We took every storm, drought, illness and comet personally. We created myths and spirits in an attempt to explain the patterns of nature.
Ann Druyan

For my own part I think no innocent species of wit or pleasantry should be suppressed: and that a good pun may be admitted among the smaller excellencies of lively conversation.
James Boswell

For the female of the species is more deadly than the male.
Rudyard Kipling
