ABSTRACT
Two anthropologists who studied the researchers at the Salk Institute describe the scientists and technicians there as “a strange tribe who spend the greatest part of their day coding, marking, altering, correcting, reading, and writing”. In the first version he says, "A search is being conducted for sequence homologies"; the subject of the sentence is the author's action, and the tone, as in the last sentence, sounds merely hopeful. The second version gives a longer discussion of the homologies before presenting the model he uses to explain them; the focus is on the matches rather than on the researcher and the theory until "our work" in sentence 6. The concluding sentence of the earlier version had put direct, immediately applicable findings first, with fundamental concepts in the second part of the sentence; here it is the direct findings that come after the "also", in the position of secondary importance to the fundamental concepts.
