Evolution is the fundamental idea in all of life science - in all of biology.
There's nothing I believe in more strongly than getting young people interested in science and engineering, for a better tomorrow, for all humankind.
There is good evidence that Venus once had liquid water and a much thinner atmosphere, similar to Earth billions of years ago. But today the surface of Venus is dry as a bone, hot enough to melt lead, there are clouds of sulfuric acid that reach a hundred miles high and the air is so thick it's like being 900 meters deep in the ocean.
I like to regard myself as someone who's capable of critical thought, that is to say, who can evaluate claims.
