If you drop an apple & observe that it falls, you get some predictive value about the nature of gravity. But that's a far cry from computing the orbital dynamics of a spacecraft. Parent's comment on "transparency" in the mapping from genotype to phenotype was more akin to the latter -- and their point stands.
We sent astronauts to the moon with Newtonian physics. No need for relativity. This is more akin to relativity in that it expands our domain knowledge and explanatory power but the old model already does most of the work.
