Every time you dive, you hope you'll see something new - some new species. Sometimes the ocean gives you a gift, sometimes it doesn't.

I am a closet birdwatcher. I can identify Southern African species, but it irks me I can barely tell a jay from a blackbird in the U.K.

If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.

Different viral species contain nucleic acids that differ not only in length and nucleotide sequence but in many unexpected ways as well.

The social relations which are the basis of the reproduction of the species are founded upon the continuous union of parents in marriage.

A marine ecologist is a scientist who studies the many species that live underwater and how they interact with each other and with humans.

Any reading not of a vicious species must be a good substitute for the amusements too apt to fill up the leisure of the labouring classes.

Think of all the different features from Asian to African to Aboriginal to Caucasian. But we are all within the same species, Homo Sapiens.

When I went to college, I really became interested in cultural anthropology. Our behavior isn't that different from other primate species'.

The thought that we're in competition with Russians or with Chinese is all a mistake, and trivial. We are one species, with a world to win.

It's always been a dream of mine, of exploring the living world, of classifying all the species and finding out what makes up the biosphere.

The reason humans experience so much more stress than other species isn't just because we think more, but also because we think differently.

Our species is on the verge of changes that will fundamentally alter what it means to be human... and we are the people driving that change.

Happiness is just another of the tricks that our genetic system plays on us to carry out its only role, which is the survival of the species.

The sooner we become a multi-planet species, the safer the species is, and the stronger the guarantee that we're going to continue to evolve.

We should explore ways to make us a more amazing species. A more fascinating society. We should embrace our innovations and evolve with them.

The human species, according to the best theory I can form of it, is composed of two distinct races, the men who borrow and the men who lend.

Babies and young children are like the research and development division of the human species, and we grown-ups are production and marketing.

What we need is an electronic encyclopedia of life, with one page for each species. On each page is given everything known about that species.

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.
