Pardon the inexact terminology from a layman, but I'm curious about why
homo sapiens has appeared in such a relatively short time compared to
modern species of crcodilians and sharks, for example.
Or is that even so?

It's probably a time perspective (our literate and technical cultures
emerged only a very short time ago, allowing us to be aware of such
questions). Modern-looking HS emerged around 200,000 years ago.
Other Homo species lasted more or less unchanged (or with minor variations)
for longer times. Homo erectus for several millions of years; neandertals
for at least a million, and in both cases with distinct cultural stone tools
and other features that did not change much. (As I understand from reading
and possible imperfect recall).
The physical distinctions are important to us, but to an alien visitor they
might hardly be noticed at first. Do you take much notice of the
differences between Bonobos and other Chimps?
