What was the average brain size for Homo erectus?
Early Homo erectus/ergaster in Africa (from about 1.7 to 1 million years ago) averaged 900 cc in brain size, but later Homo erectus specimens from . 5 million years ago average 1100-1200 cc, which falls within the range of the brain size of modern humans.
What is Homo erectus cranial capacity?
erectus, with its low profile and average endocranial (brain) capacity of less than 1,000 cubic cm (61 cubic inches), is distinctly different from that of other humans.
What is Homo sapien brain size?
about 1400 cc

How old is the human DNA?
Because of the chemical degradation of DNA over time, the oldest human DNA retrieved so far is dated at no more than approximately 400,000 years,” says Enrico Cappellini, Associate Professor at the Globe Institute, University of Copenhagen, and leading author on the paper.
Is there Neanderthal DNA in humans?
Neanderthals have contributed approximately 1-4% of the genomes of non-African modern humans, although a modern human who lived about 40,000 years ago has been found to have between 6-9% Neanderthal DNA (Fu et al 2015).
How old is human?
Although some scientists equate humans with all members of the genus Homo, in common usage it generally refers to Homo sapiens, the only extant member. H. sapiens emerged around 300,000 years ago, evolving from Homo erectus and migrating out of Africa, gradually replacing local populations of archaic humans.
What is the oldest cell in your body?
Summary: Scientists once thought that neurons, or possibly heart cells, were the oldest cells in the body. Now, researchers have discovered that the mouse brain, liver and pancreas contain populations of cells and proteins with extremely long lifespans — some as old as neurons.
What is the oldest genetic?
Genetic material extracted from a 1.2-million-year-old mammoth tooth is the new record holder for the world’s oldest DNA.
