A old tooth of a child about 130,000 years discovered.

A old tooth of a child that is at about 130,000 years old that was discovered in the cave of Laos.

Researchers believe this discovery proves that Denisovans – a branch that is now extinct of the human race – lived within the tropical warm regions of the southeast of Asia.

There is not much information about the Denisovans which is a relative of Neanderthals..

A collection of distinct tiny teeth of Artiodactyla which is the most fragmentary indicates the existence in the collection of cervids that are small and medium-sized (Fig. 6m-n, ab-ae). In the twenty-four teeth examined, there is one M3 and one m1/m2 one longer lower p2 (parastylid straight with metaconids with a posterior orientation) and two p3/p4s all worn with one elongated d2 and two D4s, as well as numerous P3/P4s exhibit shape and size that is similar to the dimensions from Muntiacus (Supplementary Data 2).

 The determination of the species is not possible using the material available. Six teeth are likely to belonged to an elongated cervid including two molars worn and fractured and one incisor. There is also one D4 (TNH2-196) as well as one missing milk tooth along with the D2 (TNH2-32). It’s morphologically as well as metrically related to the smaller-sized cervid of Tam Hay Marklot, tentatively identified as Rucervus eldii (Late Pleistocene, Laos 141) and the one from Coc Muoi (late middle Pleistocene, Vietnam 28).

The rhinocerotid specimen consists of fragments of teeth that are isolated. There are nine permanent teeth (P/p as well as M/m) and three milk teeth are not sufficiently splintered to permit an accurate identification. rhinoceros sp. (TNH2-170 TNH2-177, the TNH2-179) (or Rhinocerotina indet. (i.e. Rhinoceros (also known as Rhinoceros Dicerorhinus) (Fig. 6c-e, h). 

However, the morphology and size of the other specimens are more instructive. Two of them are incomplete teeth show morphological features and dimensions that are fully in line that of Rhinoceros sondaicus (i) the left p3 (TNH2-188) with a small thin and smooth labial cingulid as well as a narrow ectolophid groovethat is perfectly similar to that of jaw ndeg305c of Soember Waroe (Middle Pleistocene, Java and Fig. 13. Ref. 13 from ref.) and the 13 from ref. 148) and the CM1027 of Coc Muoi (late Middle Pleistocene Vietnam28) and the ii) the left d2 (TNH183) that is narrow, with an elongated paralophid,

but no anterolabial groove. It is within the region of the larger R. sondaicus taken from Coc Muoi28. A small and fragmentary right D4 (TNH2-184) with a sigmoid protoloph and an anteriorly-constricted protocone documents Dicerorhinus sp., but its fragmentary condition precludes any assignment at the species level. One Tapir ( Tapirus sp.) completes the perissodactyl taxonomic diversity of TNH2 cave, including one lophid that is the posterior (hypolophid) of an d4 fragment (TNH2-178) which is too small to be classified as Megatapirus (width: 19.5 mm instead of 22-23 mm for the other taxon) and is more compatible with T. indicus indicus and. i. intermedius25. Numerous enamel fragments which are both wrinkled and thick clearly indicate the existence of an stegodon elephantiform

Apart from these rare fossils and the Denisovans left no evidence before disappearing, except for the DNA of humans in the present.

Through interbreeding through interbreeding Homo sapiens Denisovan fragments are present in the current population of the southeast of Asia in the region of Oceania.

Aboriginal Australians and people in Papua New Guinea have up to 5 percent of the species’ ancient DNA.

Scientists have concluded “these populations’ modern ancestors were ‘mixed’ with Denisovans in southeast Asia” according to Clement Zanolli, a paleoanthropologist and co-author of the study that was published on Tuesday in Nature Communications.

There was however any “physical proof” of their presence on the Asian continent, which is far from the frigid highlands that comprise Siberia or Tibet The researcher at the French National Centre for Scientific Research informed AFP.

It was this way until a group of researchers began exploring the Cobra Cave in northeast Laos.

Cave experts discovered the cave in the mountain in the year 2018 , close to Tam Pa Ling Cave, where the remains from ancient human remains have already been discovered.

The tooth instantly appeared to be of the “typically human” shape, Zanolli said. Zanolli.

The study found that it was based on proteins from the past that the tooth was the property of the child, probably female, between 3.5 to 8.5 year old.

However, the tooth isn’t old enough for carbon-dating DNA, and it has not been preserved well because of humidity and heat said paleoanthropologist and study coauthor Fabrice Demeter.
