How tall is Turkana Boy?
5 ft 3 in
He was 1.6 m (5 ft 3 in) tall and weighed 48 kg (106 lb) when he died; if he had reached adulthood, he might have grown only a little bit taller. Turkana Boy’s cranial capacity at death was 880 cubic centimeters, but scientists estimate it would have reached 909 cubic centimeters if he had grown into adulthood.
What is the brain size of Homo ergaster?
ergaster exhibited robust craniofacial characteristics relative to modern humans, but overall we see the continued reduction in dentition and masticatory apparatus. Their brains were large, with a maximum cranial capacity of 1200 cc and a range of 800–1200 cc, based on the material from the three continents.
How long ago did ergaster live?
Homo ergaster (“working man”) is an extinct hominid species (or subspecies, according to some authorities) which lived throughout eastern and southern Africa between 1.9 to 1.4 million years ago with the advent of the lower Pleistocene and the cooling of the global climate.
How old is Turkana Boy?
1.5 to 1.6 million years ago
Turkana Boy, also called Nariokotome Boy, is the name given to fossil KNM-WT 15000, a nearly complete skeleton of a Homo ergaster youth who lived 1.5 to 1.6 million years ago. This specimen is the most complete early hominin skeleton ever found.
What did ergaster eat?
Eating meat and other types of protein that could be quickly digested made it possible to absorb nutrients with a shorter digestive tract, making more energy available faster. There is also speculation that honey and underground tubers may have been significant food sources for Homo erectus.
How big is the Dragon Man?
One of the most remarkable aspects of the Harbin cranium is its massive size, which, at 9 inches long and more than 6 inches wide, is significantly larger than the modern human skull.
Who was the first man in Kenya?
These were Paranthropus boisei (2 million years old) and Homo habilis (1.9 million years old). In August 1984, Kamoya Kimeu found a small piece of hominid skull, identified as Homo erectus, on a dry river bank in Nariokotome, on the western side of Lake Turkana. It was nicknamed Turkana Boy (Nariokotome Boy).
Is ergaster and erectus the same?
ergaster and Homo erectus are the same species. While some researchers make no distrinction, others argue that H. erectus evolved from the H. ergaster ancestor in Asia, and H.
What is the average weight of a female Homo erectus?
Weight: Ranges from 88 – 150 lbs (40 – 68 kg) Height & Weight Supplemental Information: There was a large amount of variation in the size of Homo erectus individuals. Many fossils cannot be attributed to male or female, so we present the entire size range here.
What was the average lifespan of Homo erectus?
What was the life expectancy of Homo Habilis, Homo Erectus, and early Homo sapiens? Is 18 to 20 years about right, with the oldest age around 40? Your figures are about right for maximum life expectancies. Individuals in their 40s are extremely rare. Some scholars place the age of the “old man” of La Chapelle aux Saints in its mid-30s.
What was the average height of Homo erectus?
Homo erectus was taller and more slenderly build than all other Homo species. The average height was 5 ft and 10 inch. Homo erectus got their food through hunting and gathering. Had shovel-shaped teeth larger than those of homosapien. Homo erectus females were significantly smaller than males.
What is the cranial breadth of a Homo erectus?
Wider at the base than in earlier & in later homos. Maximum cranial breadth is below the ear opening, giving the cranium a pentagonal shape when viewed from behind. (In contrast, earlier homos have more vertical sides and widest breadth ABOVE ears. Most also have sagital keel running midline of skull.
