The adventurer in all of us, the homo erectus.
Not only does he influence his own evolution due to use of fire and obsidian since 1.9 million year ago but shapes the later hominid in Europe, Asia and Africa.

The place for the oldest proof of fire and use of obsidian, an volcanic sediment is near the oldest know continue habitat of hominid since also 1.9 million year, the Melka Kunture.

It should be no surprise both technology's and first permanent habitat in Ethiopia is a hotspot for volcano's.
And it's my belief the mastering of fire is not due to an natural phenomena as a periodic lighting, if we look at the migration path of those hominid they follow the volcano's out of Africa, as we can see in Saudi-Arabia.
Their technological advance in stone-technique based on a volcanic stone forced them near the fire of it, got used to it, observed it's property and applied it to better their own living conditions, probably already started with the homo habilis which effected their offspring.
Since then human brain volume evolves gradually, this if we ignore Homo Naledi and Homo Floresiensis which are both dwarf hominid.

We know that elite institutions like the one Flier was in (partial) charge of rely on irrelevant status markers like private school education, whiteness, legacy, and ability to charm an old white guy at an interview.

Harvard's discriminatory policies are becoming increasingly well known, across the political spectrum (see, e.g., the recent lawsuit on discrimination against East Asian applications.)

It's refreshing to hear a senior administrator admits to personally opposing policies that attempt to remedy these basic flaws. These are flaws that harm his institution's ability to do cutting-edge research and to serve the public.

Harvard is being eclipsed by institutions that have different ideas about how to run a 21st Century institution. Stanford, for one; the UC system; the "public Ivys".
