Man came to Europe's colder shore,
And found Neanderthals in place -
Cousins of the human race.
They interbred - Their DNA
Is in non-Africans to this day,
And in our health may find expression,
Like in allergies or in depression.
Now, of Cold Spring Harbor Dr. Siepel
Published in Nature a revelation:
He found that very ancient people
Were in an unknown migration.
In a Siberian cave of stone,
A fossilized toe was found,
And this Neanderthal old bone
Caused a sensation all around,
For when the toe's bone was assayed,
A strange story it then told:
It had chunks of human DNA,
And it was 100,000 years old!
It doubled the time when Man set forth
From Africa, to regions North.
Thus can of DNA a trace
Change the story of our race!
