Extinct Denisovan Gives Finger to Science

An extinct human species gave the finger to human scientists of today that enabled the sequencing of the genome of the closest relative to human beings that died about perhaps 40,000 years ago. The Denisovan remains were discovered in a Siberian cave.

The finger and some teeth date to about 100,000 B.C., yet the Denisovans lived for about 60,000 years elsewhere in Asia. Australian aborigines and New Guineans have aboye 4 to 5% Denisovan genes

The Denisovans are interesting for many reasons. One is their timing in the human schedule of travel to America via the Bering Sea land mass. American indians did not arive here until after 40,000 B.C. by which time the Denisovans were about extinct.

Scientists have discovered remains of homo erectus in Asia dating about 1.8 million years ago. Human beings arrived in the far east it is reported in two basic migrations from about 45,000 thousands y.b.p to 35,000. Then later human beings arrived about 25,000 b.c. Those humans became the Chinese and perhaps pressured migrations across Berengia to Alaska. I would guess that American indians have low or now Denisovan genes.

Modern Europeans have 2 or 3% Neanderthal genes. Of more interest is the idea that the human line originated in Asia as homo erectus and then traveled to Africa only to return 1.8 million years later to loan money to finance the federal debt. One wonders if American President have more Neanderthal genes than Asian leaders who perhaps have neither Denisovan or Neanderthal genomic content evidently. Where are Jerry Ford quality leaders when America needs them?
