No one is born with an adam's apple. It is a side effect of testosterone on the body, which causes the larynx to change shape and move lower in the throat. Babies don't have adam's apples, and few male children do either.
And yes, it means those trans kids who have supporting parents who put them on blockers then allow them to start HRT at 15-16 will grow up without any residual male side effects like that.
I've said this before and elsewhere but we are probably a generation or two away from where transitioners like you and me will almost no longer exist. If being trans comes to be accepted as a treatable medical condition in the next 50-75 years, very few children in first world nations will ever grow up in the wrong gender. The social awkwardness, the dealing with residual effects of testosterone poisoning - those will be things of the past.
So in a sense, as we come out into the public eye now, as we transition as adults, this could be a very temporary thing with the majority of trans kids transitioning when young and being socialized in the gender with which they identify. In a sense, I guess the period before modern medicine could be considered one era, and the eventual arrival of early treatment of trans conditions being another era, and we're the evolutionary transitional forms in between one era and the next, not destined to remain in any serious numbers, and maybe not even well understood if our history isn't preserved going forward.
