The cranium or skull segment of Australopithecus sediba, a young male, has been unearthed in close proximity to the place in Africa where he had breathed his last breath.Food tidbits have been found wedged in the teeth of a tow million year old human antecedent.The new study says,the bits of food found suggest that some of the human ancestors munched on tree bark.
The teeth full of bark indicates the character of the Australopithecus sediba species as a wild primitive living in the comforts of the woods and following a chimpanzee like way of life. Other two-legged animate and active at that point in time are thought to have gorged mainly on savanna grasses.
A. sediba was acknowledged from the well conserved fossil remnants of a young male and a female noticed in a South African cavern in 2008 by scientists directed by National Geographical Society grantee and paleoanthropologist Lee Berger."We think these two individuals fell down a sinkhole ... and were quickly covered in very fine-grained sediment that created an environment of very little oxygen," exclaimed Amanda Henry, a paleobiologist working at Germany's Max Planck Institute for Evolutionary Anthropology."So there wasn't a lot whole lot of bacteria or decomposition, and there certainly wasn't any interaction with the air, “said the lead author Henry.
That stuffy and unventilated entombment presented itself in an unusual preserved state —to the point that even minuscule, fossilized specks of plant tissues that had been consumed were ensnared in dental plaque. The phytoliths that is the properties of the ancient specks and the carbon isotope data when compared with recent examples helped the team in identifying the parts of the plants from the dental tartar. For a few cases the scientists could even identify the plant type consumed. The Sediba most probably satisfied their hunger with leaves, wood fruits, bark, and other forest vegetation.
"We had a palm [tree] phytolith," Henry further said. "We weren't able to tell whether it came from the fruit or the leaf or another part of the palm, but we could definitely identify that it came from that family of plants." Just like the modern gorillas and Chimps who stuff themselves with bark the study findings point out that the A. Sediba‘s chose to feed in wooden and close surroundings. The A.sediba is also suspected to use simple tools to acquire food and climb trees. They had ape-like long arms, accuracy in their grip, and wrists adjusted to climb.
"The way I interpret this is that, around two million years ago, our ancestors and relatives were exploring a variety of environments and behaviors within those environments," Henry said.
