[32] An early research initiative emerged in 1878 when Alpheus Hyatt led an investigation to study the laws of heredity through compiling data on family phenotypes (nose size, ear shape, etc.) and expression of pathological conditions and abnormal characteristics, particularly with respect to the age of appearance. One of the projects aims was ...
The lack of 32 P-labeled DNA remaining in the solution after the bacteriophages had been allowed to adsorb to the bacteria showed that the phage DNA was transferred into the bacterial cell. The presence of almost all the radioactive 35 S in the solution showed that the protein coat that protects the DNA before adsorption stayed outside the cell.

[32] In particular, Feldman and Lewontin emphasize that heritability is itself a function of environmental variation. [33]
