If we think of every generation as a compression step of some form of information into our DNA and early humans existed for ~1.000.000 years and a generation is happening ~20years on average, then we have only ~50.000 compression steps to today. Of course, we have genes from both parents so they is some overlap from others, but especially in the early days the pool of other humans was small. So that still does not look like it is on the order of magnitude anywhere close to modern machine learning. Sure, early humans had already a lot of information in their DNA but still

It only ends up in the DNA if it helps reproductive success in aggregate (at the population level) and is something that can be encoded in DNA.

Your comparison is nonsensical and simultaneously manages to ignore the billion or so years of evolution starting from the first proto-cell with the first proto-DNA or RNA.
