Document Summary
Science is social knowledge because valued theories, methods, etc. are ones that scientists agree on: things that are found useful become part of the canon. Science is social because scientists are socialized and interdependent: the(cid:455) use ea(cid:272)h othe(cid:396)"s (cid:396)esults, (cid:373)ethods, tools, a(cid:374)d ideas.

Scientific writing is social; it is constructed in anticipation of its critical reception, and in response to actual criticism in the review and revision process. It is a passionate argument written with an objective style.

At the level of dna, evolutionary changes can be treated as random, rather than as adaptations to an environment. Dna is made up of 4 nucleotides: adenine, cytosine, guanine, thymine (a,c,g,t)
