Skip to comments.Scientists 'Surprised' to Discover Very Early Ancestors Survived On Tropical Plants, New Study...

An international research team extracted information from the fossilised teeth of three Australopithecus bahrelghazali individuals -- the first early hominins excavated at two sites in Chad. Professor Julia Lee-Thorp from Oxford University with researchers from Chad, France and the US analysed the carbon isotope ratios in the teeth and found the signature of a diet rich in foods derived from C4 plants.
Professor Lee-Thorp, a specialist in isotopic analyses of fossil tooth enamel, from the Research Laboratory for Archaeology and the History of Art, said: "We found evidence suggesting that early hominins, in central Africa at least, ate a diet mainly composed of tropical grasses and sedges. No African great apes, including chimpanzees, eat this type of food despite the fact it grows in abundance in tropical and subtropical regions. The only notable exception is the savannah baboon which still forages for these types of plants today. We were surprised to discover that early hominins appear to have consumed more than even the baboons."
The research paper suggests this discovery demonstrates how early hominins experienced a shift in their diet relatively early, at least in Central Africa. The finding is significant in signalling how early humans were able to survive in open landscapes with few trees, rather than sticking only to types of terrain containing many trees. This allowed them to move out of the earliest ancestral forests or denser woodlands, and occupy and exploit new environments much farther afield, says the study.
The fossils of the three individuals, ranging between three million and 3.5 million years old, originate from two sites in the Djurab desert.

The Scars of Evolution"The most remarkable aspect of Todaro's discovery emerged when he examined Homo Sapiens for the 'baboon marker'. It was not there... Todaro drew one firm conclusion. 'The ancestors of man did not develop in a geographical area where they would have been in contact with the baboon. I would argue that the data we are presenting imply a non-African origin of man millions of years ago.'" [Primary Literature by Jonathan Marks

Just adding to the catalog, not sending a general distribution.
From carbon isotopes the whiz kids say that this beast/man chowed down on grass or sedges?
I’d like to know how this got figured out. What if they ate beef... which in turn ate the grass or sedges?
we weren’t allowed to eat meat until after the flood, no surprise here.
I’m surprised at how Mick Jagger can play bluesy harmonica the way he does...
That was the time of the first quotation of a divine affirmative statement in scripture about it; however the concept of animal sacrifices was much older (it was the point of friction between Cain and Abel), and the use of skins was obviously deemed okay. It would be surprising if in such a situation people yet remained vegetarians.
I’d want to know how the whiz kids deduced this. Humans and humanoid animals have traditionally been omnivores.
interesting but I doubt we know half of it
Well, it seems that very early man knew how to chew those pesky plants that soaked up CO2, to give him energy whilst balancing the CO2 of the planet for thousands of later generations to enjoy the sun on a beach
The use of skins was deemed okay because God Himself first made coverings for Adam and Eve out of an animal skin.
However the sacrifices were burnt offerings and they were consumed by the fire. Nowhere in the sacrifice rituals did anyone ever eat the animal after it was made a burnt offering to God.
Permission was given only after the flood, after the entire earth’s ecosystme had drastically changed. And at this time God put fear of man into animals because of this change, so that they wouldn’t be hunted to extinction.
This is, at best, speculation.
Quickly following on the heels of the Fall was a time when men stopped caring about the Lord. To assume that people remained faithful to a command to be vegetarian is naive.
I knew my ex-wife would use the Christmas present I bought her three years ago.
Your viewpoint is as speculative as mine, as the fruit and vegetation before the flood grew greatly and was watered from below the ground, all various kinds of edible fruits and nuts and plants were in abundance and nobody would have needed to eat meat.
However, whether some did or didn’t, what is fact is that permission for peole to eat animals was not given until after the Flood, and the fear of man was not placed in animals until after the Flood.
It is a crucial point to the credibility of omnivore diets vs. vegetarian to note that disobedience was the norm — in fact meat may have been viewed not just as something nice but as an overtly pagan act.
Funny post....this guy has massive forearms....quite impressive...
It would seem possible the species of the tooth in question was from a non humanoid species.
I would agree on the last point you make, it could very well have been regarded as a pagan act, act of rebellion, etc. But again, we don’t know as there are no affirming statements of it being done before the flood, and with those people being evil and not possessing complete knowledge and separation from God, they could have also just as easily come to believe eating meat was a dangerous thing to do, as inevitably if it was tried people may have died eating spoiled meat. Maybe they thought the other animals and insects may be okay doing it, but not people. You have to realize since God didn’t permit man to eat meat yet, He’d have shared no knowledge of preparing meat, storing it, etc. On the other hand we see that when He instruted man to make burnt offerings to Him He did spend time explaining how to make a proper offering, on what, what to use for a proper offering, etc.
