If you had such a camera, you could put it into bedrooms without risk of being caught because nobody would know what it was. But this usefulness would diminish as you reach the pre-trimming and grooming era and when chubby chicks were considered hawt. I guess there will always be limitations to science.

if the current model of macroevolution is accurate (it isn't, cap this post), we're looking at maybe 250 million years, and then you have to consider the slow decrease of years between generations as you go back. your parents probably had you at 20-30, same with grandparents, but after a couple hundred years they were more like 15-20 on average, then when you get to primates that's like 3-5 years, and after that point you're pretty much guessing

How come rats can have thousands of generations within 100 years and they never evolve or change whatsover
