First Molar « lancalass

My Sister Pauline, called Home Too Soon.

If tears could build a stairway and memories a lane , I would walk right up to heaven and bring you back again.

The greatest gift our parents gave us..was each other.

If I had a flower for every memory I have with you, I could forever walk in my garden.

Rest In Peace knowing how much I love you!!

All I ask is that you remember me at the alter of God.

A sundown splendid and serene,
A sister’s kiss upon your cheek,
A timeless moment when you are thanked,
You smile but cannot speak.
Such gifts are rich beyond compare,
And compensate for grief and care.
We lost a very special sister and best friend the day you were called home so suddenly and without warning..
Loved with a love beyond all telling,
Missed with a grief beyond all tears.
Goodnight and God Bless Pauline I love you and miss you so much…xxx

Re-united with her loving parents and brothers Peter and John, sister Patrica. Missed by her loving husband Peter also daughter Susan and Ebony her granddaughter,  son Anthony, and Grandsons.. Not forgetting  Brian and Granddaughter Julie.

All of you Rest In Peace!

 

First Molar

An old, unusual tooth discovered in China reinforces the theory that Homo sapiens and an extinct human species, the Denisovans, swapped genetic material — and physical traits — thousands of years ago.

The tooth, a molar with three roots, belonged to a jawbone found remarkably high in a mountain cave on the Tibetan Plateau. Anthropologists announced the discovery of the jaw, which predated modern human settlement of the region by 100,000 years, in May. A new paper, published this week in the Proceedings of the National Academy of Sciences, is the first to describe the jaw’s three-root tooth in detail.

Three roots in a lower molar are rare in modern humans. The overall prevalence in non-Asian people is about 3.5 percent. In Asian and Native American populations, though, the proportion of three-rooted molars rises to about 40 percent. Given this, scientists had predicted that the characteristic arose recently in human history, as people dispersed into Eurasia. (A person who lived in the Philippines almost 50,000 years ago had such a tooth.)

Yet the discovery indicates humans may have inherited the feature from Denisovan ancestors. “Its presence in a 160,000-year-old archaic human in Asia strongly suggests the trait was transferred to H. sapiens in the region through interbreeding with archaic humans in Asia,” said study author Shara Bailey, an anthropologist at New York University, in a statement.

This new study doesn’t offer direct genetic evidence of hybridization; the scientists have been able to pry ancient proteins, but not DNA, out of the mandible. But the feature is a strong sign of interbreeding, the scientists said. “We now have very clear evidence that gene flow between archaic groups and H. sapiens resulted in the transfer of identifiable morphological features,” they wrote in the new study
.

The Denisovans were first identified as a species based on a finger bone in 2010 found in Siberia. Later genetic tests showed they mated with Homo sapiens, as well as Neanderthals. As my colleague Sarah Kaplan wrote last year, some scientists compare the planet during this age of prehistory to J.R.R. Tolkien’s Middle Earth: “Except instead of hobbits, dwarves and elves, there were different kinds of humans.”
