And we have a century more of understanding and refinements we can explore should we so desire, all at the press of a button.
They would only dream of the access to science and people we have now. Though twitter would be a poor medium to replace that era's epistolic cross-polination.
Yes, you can look it up. But that's not the same as having an intuitive feel for all of science at the deepest level.
But if you want something shorter, ponder this: What percentage of journal article material makes it to textbooks, and how has that changed over time?
I think that says as much about the quality of journal articles and academic incentives as much as anything.
A child on the internet today has to contend with deliberate science misinformation that tries very hard to look valid and authoritative (flat earthers, antivaxxers). This stuff is also likely to intersect with entertainment venues like YouTube and plant their ideas first where you then have to unteach the nonsense just to begin. Even as a science literate adult, navigating this with my children is hard because it brings difficult topics to the table well ahead of their age appropriate academic abilities traditionally prepare them for (religious motivations, philosophy, logic, history, etc).

And
>Not really no. A single person can no longer know, grok even the whole of biology, or even the whole of molecular biology.
have always struck me as odd statements to make.
Not to get pedantic, but that's more of a commentary of our classification of knowledge than the kind of tasks they had to deal with. They were presented with the same living beings that we have today (well, those that aren't extinct anyway). No more, no less.
They had plenty of chances to get overwhelmed with what was in front of them, regardless of what their contemporary science had figured out already.
Put another way, not knowing how things work didn't make their jobs any easier. The way things work doesn't change no matter how many branches of science you throw at it.
It really really did. You could make major scientific discoveries by walking in a forest for a couple of hours.
