But really what we should have said was

Anatomical structures, or physiological mechanisms, with no apparent purpose present challenges to evolutionary biologists. Do such structures serve some hidden function that hasn't yet been discovered? Or are they relics of our evolutionary past, having once served some important purpose

Quote examples
Lydia Millet
American Novelist
Without even knowing why, we believe that to learn how to be human - which we have many years to do, for human beings have longer childhoods than any other species, a feature that to biologists and philosophers alike is one of our race's distinguishing characteristics - children must be surrounded by animal imagery.

Quote examples
Leonardo DiCaprio
American Actor
As a kid, I was going to be a marine biologist or an actor. When I became successful as an actor, I said, 'Well, maybe I can lend a voice to this with an equal passion.' You realize how lucky we are and how destructive we've been and what little regard we have for the natural world.

Quote examples
Barry Barish
American Physicist
Anything that makes us take more seriously scientists - or economists or chemists or physicists or biologists - I think is helpful in times when things get distorted because of people not paying attention to all the facts.

Quote examples
Christian de Duve
Belgian Scientist
What I was concerned with was life: what are the major features that are common to all living organisms that subtly define life. So I looked at the whole problem as a chemist, as a biochemist, and as a molecular biologist.

Quote examples
Tom Hodgkinson
British Writer
Now I'm no biologist, but it seems to make a lot of sense that slow lives, as well as being enjoyable, are long lives. One only has to think of the example of the tortoise for proof of this theory from the animal world.

Quote examples
Sheldon Lee Glashow
American Physicist
I think that we scientists are seeking an understanding of the natural world. We come in various types - chemists and physicists and biologists and such - and we all have the same goal. We are making progress.

I just was mesmerized by all of this life everywhere I looked. And so I wanted to be a marine biologist.

Ashley Roberts
American Musician
I wanted to be a marine biologist when I was growing up and always wanted to be surrounded by wildlife.

Ricky Schroder
American Actor
I weren't an actor, I'd be a wildlife biologist or forest ranger.
