Clearly, we are a species that is well connected to other species. Whether or not we evolve from them, we are certainly very closely related to them. A series of mutations could change us into all kinds of intermediate species. Whether or not those intermediate species are provably in the past, they could easily be in our future.

George M. Church

Seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends.

Charles Darwin

We observe closely related species in sympatry and infer how they evolved from a common ancestor.

Peter R. Grant

There is part of a structure in which every species is related to every other species. And they're built up on species, like a pyramid. The simpler cell organisms, and then the more complicated ones, all the way up to the mammals and birds and so forth. We call it 'developing upward'... The whole thing depends on every part of it. And we're taking out the stones from the pyramid.

W. S. Merwin

On the whole, at least in the author's experience, the preparation of species-specific antiserum fractions and the differentiation of closely related species with precipitin sera for serum proteins does not succeed so regularly as with agglutinins and lysins for blood cells. This may be due to the fact that in the evolutional scale the proteins undergo continuous variations whereas cell antigens are subject to sudden changes not linked by intermediary stages.

Karl Landsteiner

So you love me," said Petra softly when the kiss ended. I'm a raging mass of hormones thet I'm too young to understand," said Bean. "You're a female of a closely related species. According to all the best primatologists, I really have no choice." That's nice," she said.

Orson Scott Card

Every species has come into existence coincident both in space and time with a pre-existing closely allied species.

Alfred Russel Wallace

Bird taxonomy is a difficult field because of the severe anatomical constraints imposed by flight. There are only so many ways to design a bird capable, say, of catching insects in mid-air, with the result that birds of similar habitats tend to have very similar anatomies, whatever their ancestry. For example, American vultures look and behave much like Old World vultures, but biologists have come to realize that the former are related to storks, the latter to hawks, and that their resemblances result from their common lifestyle.

Jared Diamond

The rapidly spinning blades of wind turbines act like an apex predator that big birds never evolved to deal with. And because big birds have much lower reproductive rates than small birds, their deaths have a far greater impact on the overall population of the species.

Michael Shellenberger

Lust and self-mutilation are closely related impulses. There are also self-mutilators among knowers: they do not want to be creators under any circumstances.

Friedrich Nietzsche

I was convinced that the trading frequency measured a fundamental heartbeat of financial markets. Clearly it reflected the flow of information. It turns out also to be closely related to measures of liquidity.

Robert F. Engle

Cats, dogs, and some I mean, birds, many species of mammals, they also have the sort of potential to show affection firstly because of the biological factor.

Dalai Lama

The Creator would appear as endowed with a passion for stars, on the one hand, and for beetles on the other, for the simple reason that there are nearly 300,000 species of beetle known, and perhaps more, as compared with somewhat less than 9,000 species of birds and a little over 10,000 species of mammals.

John B. S. Haldane

Feasting is also closely related to memory. We eat certain things in a particular way in order to remember who we are. Why else would you eat grits in Madison, New Jersey?

Jeff Smith

I think a lot of people fail to work on their sight, even though it's probably one of the most important sides to tennis. It's also about reactions and concentration and focus, and I think it's all very closely related.

Kevin Anderson

China's culture and history are closely related to my living environment. This country is my birthplace. It is also where I grew up. Its culture and history shape my relations with family, friends, society, and daily life.
