I recently saw an archeologist talk about this very thing. His conclusion: archeology actually takes great pains to infer gender roles based on artifacts and cultural context, not merely bones. Some ancient peoples had wildly different conceptions of gender than us, which often don’t align with biological sex. “We don’t dead name the dead” he said.

That’s true, even if the specific example doesn’t hold, the core concept does. If I needed to implement a bird detector today, I’d make an API call to AWS Rekognition or an equivalent service. It would take me a day or two to learn the API and then maybe 4 hours to actually implement. But if you asked me to implement a bird species detector, I’m pretty sure there is no off the shelf API capable of that, and I would indeed need months or years.
