Atoms Quote by Francis Crick
“Haemoglobin is a very large molecule by ordinary standards, containing about ten thousand atoms, but the chances are that your haemoglobin and mine are identical, and significantly different from that of a pig or horse. You may be impressed by how much human beings differ from one another, but if you were to look into the fine details of the molecules of which they are constructed, you would be astonished by their similarity.”

Molecular similarity doesn't explain phenotypic diversity.
![“[Decoding the human genome sequence] is the most significant undertaking that we have mounted so far in an organized way in all of science. I believe that reading our blueprints, cataloguing our own instruction book, will be judged by history as more significant than even splitting the atom or…” quote by Francis Collins](https://sms4smile.com/quotes/img-quotes/5c6/francis-collins-5281_atoms_decoding-the-human-genome-sequence-is-th_15604.jpg)
