Biology nowadays is filled with mathematics. Indeed, the field of mathematical biology is huge, and shows no sign of decay. But the mathematisation of biology is, to my knowledge, a recent phenomenon - dating to the early 20th century with the contributions of Ronald Fisher and his contemporaries.
Any resources detailing the history of this quantification would be fascinating to read; in particular, something which comments on the birth of mathematical biology and its relationship to biology done in the field or in the lab. But I can't find much! I'm looking for recommendations - books, articles, anything - on this aspect of the history and philosophy of biology.
