The chemicals in their nearby environment are what make the embryos develop into Queen bees. It makes one wonder what sort of nearby chemical environments do to human embryo development.

Since human fetuses are usually encapsulated within the womb of an adult woman, they’re far more insulated from arbitrary chemical environments than bee larvae. But of course we know of many cases where chemicals make it through the mother’s body and into the fetus’s immediate environment, affecting its development: https://www.mayoclinic.org/diseases-conditions/fetal-alcohol...

Temperature is another factor. IIRC amphibian embryos have to develop in a wide range of temperatures (an egg might be stuck to a leaf), so their cells have many more variants of proteins, where each variant is most-effective in a different temperature band.
In contrast, a mammal blastocyst or embryo already has the multicellular mother keeping temperature within a narrower band.

Another interesting example is sea turtles, whose eggs are in a relatively stable environment (sand), but its temperature changes year to year. Based on the temperature of the eggs, you see a different distribution of offspring sex.

I guess having just read about the positive impact the bees have to develop into Queen bees I was wondering if there are positive chemicals a human female could produce to give better than average outcomes.
