Homo erectus

erectus appears to have been the first human species to control fire, some 1,000,000 years ago” (Homo erectus). One million years ago falls right in the middle of the paleolithic area, marking the mastery of fire as a hallmark achievement of the time. Homo erectus, an ancestor of humans, had a larger jaw complete with sizable teeth, and a smaller brain than the modern human. The mastery…

The advent of several early Homo morphological changes is due to the increased availability of nutrients in the foods that they ate, primarily due to the cooking of these foods. The decrease in the size of the organs involved in digestion and the increase in brain size are due to several converging factors that accentuate each other in a constant feedback loop. Raw plant foods were the majority of early hominid diets and tubers were particularly important and the cooking of these foods would…

primates that possess characterics like bipedalism, smaller canine size and bigger brain size are hominins. Humans are the modern Hominins and the fossils reveal that several species of hominins are extinct. Homo is a type of Hominin that lived around 1.9 m.y.a and it is the immediate predecessor of Homo sapiens. Paleontologists and archeologists have classify each time they discover new fossils that have primates and or derived characteristics. The two groups of anthropologists are lumpers and…

man today. As evolution moves toward the modern man we are introduced to the homo erectus and the homo neanderthal. They were basically cavemen. They had an improved posture and a mental delay. Though most importantly, these creatures developed a hunter-gatherer society and they made and used tools. This is a remarkable improvement to man’s societal habits which did not necessarily exist until the homo erectus/homo neanderthal…

last one is the homo groups is about 1 million years ago. Ardipithecus kaddaba was discovered in Ethiopia in 1997 by a paleoanthropologist Yohannes Haile-Selassie and was dated to 5.8 million years old. Ardipithecus group is similar to modern day chimpanzees because of the bones and facial structure. Ardipithecus kaddaba was about the same weight and height to chimpanzees. Another one is Ardipithecus Ramidus discovered in 1994 by…

habitats and animals, or intrinsic. (Flower 2016)They lived in groups. This indicates H. erectus had a way of communicating with their own people. Especially, H. erectus began to use tools and were leaning for hunting. One of these hunting tools were biforal tools which were hand axes and havers. They were flexible tools for people to use. As well as, using fire to cook their food. This had many benefits that H. erectus were communicating more. There were more calories for them to consume and…

also the broad shape of these hip bones of that of Homo erectus are very similar to those of modern humans, this shows that this early form of human species completely stopped climbing to take on full bipedalism as way of getting around. Its till 1.9 millions years ago that early specie of man became fully bipedal with the pelvic and also the thigh bones from the specie of Homo erectus are similar to those of modern humans, this showed that Homo erectus would be able to walk long distances. This…

of the foot and ankle of Chimpanzees and Homo sapiens sapiens show several distinct changes. These changes developed mainly due to the transition from quadrupedal to bipedal movement and becoming more terrestrial rather than arboreal. When researching different hominids in chronological order, it is clear that each change in our foot morphology occurred at a different time in our evolutionary history, and not all traits are exhibited in extinct lines of Homo and other hominid relatives. When…

1. The physical states observed in the species were primarily ancestral characteristics ranging from the more distinct species, gorilla gorilla, to modern human, homo sapiens, they all had molars, flat face with forward facing eyes. Ancestral/primitive characters are the characters that were present in a common ancestor whereas the derived characters are those type of characters that were not present in the common ancestor. One of the observed characteristics for derived characters are large…

uncovered are the remains of the unknown species, Homo naledi (Mckie). The discovery of the new species sparked a plethora of controversies. Homo naledi’s physical features represent both primitive and modern characteristics. Berger and his team deduced that there is significant differences in characteristics between H. naledi and H. erectus. However, some scientists claim the bones do not indicate a new species, but rather a known hominid species, Homo erectus. According to White, “Berger’s…
