That strays into the eugenics region. Not there yet; the moral and legal 'obstacles' will be present for a long while.

I've never heard Eugenics defined in this way. I've only heard it used to mean selective planned breeding (as we do with livestock), but not intentional selective improvement of the parents' DNA.

Totally worth peeking into, it's interesting what many countries have considered, have attempted, and are continuing to ruminate on.

mtDNA is also very significant in historical migration studies... if anyone has a high level explanation of the global state of knowledge in this area I would love to see it ... trying to author a regionally focused ancient history book and piecing together the disparate pieces of supposed genetic evidence for various things is a task I am wholly unqualified for and would love some assistance with.

It is often thought that humanity will leave no trace of its existence for the next civilization that will come, say, 20 million years from now. But I'd submit that unless something catastrophic happens very soon, one of the signs that "something" happened will be this sudden discontinuity in species history where suddenly the laws of genetics were thrown out the window for some reason, leaving its evidence both in the fossil record and in the attempts to plot out species trees based on genetic similarity.

What today we are pleased to panic about in the "Holocene extinction" may in fact just be the opening act to an explosion of diversity, and the two events would not be distinguishable in the historical record.

Hitler got some of his worst ideas from the Eugenics Institute in California. Such as 'humanely' gassing undesirables and 'genetic defectives'. Eugenics, from Galton on, was considered progressive, enlightened, 'scientific' thought at the time.

We have pretty good Trilobite fossils from 400+ million years ago. Why would they leave a trace and humanity not? (given all the stuff we produce: cities, cars, etc.)

There were a lot more trilobites than there are humans. And they lived in places more conducive to fossil formation.
