the first generation offspring of these immigrants had heads shaped more like New Yorkers or Puerto Ricans than like the European parents.
It's a very interesting observation, but it proves nothing. What would be required is a series of measurements over multiple generations and then to show that those changes can overpower genetic differences. For as far as we know they might have been moulding into an ostrich with New Yorkers being an intermediate state. Meanwhile, reappropriating Malthus' quote:
A writer may tell me that he thinks man will ultimately become an ostrich. I cannot properly contradict him. But before he can expect to bring any reasonable person over to his opinion, he ought to shew, that the necks of mankind have been gradually elongating; that the lips have grown harder, and more prominent; that the legs and feet are daily altering their shape; and that the hair is beginning to change into stubs of feathers. And till the probability of so wonderful a conversion can be shewn, it is surely lost time and lost eloquence to expatiate on the happiness of man in such a state
Also, I don't know how changes were measured, but fat distribution or weakened bone structure due to different diet could potentially explain some of it. And the fact that black people in USA are still black, and whites are white, and mexicans distinctly mexican proves that extrapolating the changes ad infinitum till we're all one grey race was wrong.

Visually, obviously.
Racial differences are bones deep (or even deeper) as shown by MIT study where Deep Learning model could predict race from X-ray images.
In the end, you're just begging the question: Ray Peat said everything is environmental or metabolic; ergo, race (or cognition) is environmental or metabolic.
