Dualism isn’t even that old, Cartes is from AD, and it’s not even the only competition to Physicalism there is
Physical Reductionism is weak as it requires all sciences to be reduced solely to physics, which just isn’t feasible nor is there precedent for one science to be made obsolete by the existence of another. (I mean Alchemy -> Chemistry, Astrology -> Astornomy sure, but… There’s never been a case of something like “We know enough about Psychology to know that we don’t need Marine Biology anymore!”
Dualism was exposed as bankrupt at least 2500 years ago. Not everyone has picked up on that, obviously.
Disciplines are collapsing in on each other. Both chemistry and biology are slowly collapsing into physics. The only reason biology might not completely fold into physics is practical: Biology is too complex. There isn’t any theoretical reason why it shouldn’t.
Edit: Psychology is the study of the human brain, but humans are mutated fish, so all that’s needed to link Marine Biology to Psychology is to ground Psychology in Biology, which is happening more and more.

That would be an incredibly impressive feat to disprove it more than a millennium before the idea was even proposed in philosophy
