The science of life; that branch of knowledge which treats of living matter as distinct from matter which is not living; the study of living tissue. It has to do with the origin, structure, development, function, and distribution of animals and plants.
In my school, the brightest boys did math and physics, the less bright did physics and chemistry, and the least bright did biology. I wanted to do math and physics, but my father made me do chemistry because he thought there would be no jobs for mathematicians. Stephen Hawking
You can't even begin to understand biology, you can't understand life, unless you understand what it's all there for, how it arose - and that means evolution. Richard Dawkins
Science is beautiful when it makes simple explanations of phenomena or connections between different observations. Examples include the double helix in biology and the fundamental equations of physics. Stephen Hawking
Biology is the study of complicated things that have the appearance of having been designed with a purpose. Richard Dawkins
In the nearer term, I think various developments in biotechnology and synthetic biology are quite disconcerting. We are gaining the ability to create designer pathogens, and there are these blueprints of various disease organisms that are in the public domain - you can download the gene sequence for smallpox or the 1918 flu virus from the Internet.
