Homo Sapiens vs Homo Erectus
It is the scientifically referred name for the modern man, and the two names together means the man who thinks or the wise man. The human is one of the most distinguished species of the entire animal kingdom. They perform highly complex activities and solve serious matters or problems using the exceptionally large brain compared to the body size. It has been a widely accepted fact that the human’s primary weapon is the brain, or in other words, the intelligence of man could never be beaten by any of the forces in the universe. The highly complex and developed brain of the humans has the ability to theorize languages, justifications, problem solving, and many more functions. Humans are distributed all over the world including the ice-cold snowed lands all around the year, but not in Antarctica. They are culturally different among nations as well as within nations and countries. Mainly, there are three morphological types of humans known as Mongoloid, Caucasoid, and Negroid. However, the number of differences among human individuals is countless, because all the human individuals are extremely different from each other in their external appearance as well as from their thoughts. Nevertheless, the physiology has no much difference from the related species. Usually a healthy average adult human weighs about 50 – 80 kilograms while the height could vary from 1.5 to 1.8 metres. Despite the fact that humans are the most sophisticated species ever known to live on the Earth, the ability to stand out any major disaster or a climatic or geographic shift is unknown, but other animals have proven their abilities in such occasions.
Homo erectuswas one of the hominid species, which is now extinct from the world. They were the first to stand in a standard upright posture out of all the hominids, and that has given their species nameerectus. According to the fossil evidences, they lived until 1.3 million years from today and the earliestHomo erectus化石可以追溯到180万年。直到衰退nt findings about the fossils ofHomo habilis，人们相信H. erectus descended into H.neanderthalensis. However, now the scientists state that both these species lived together for at least 500,000 years.H.erectuswas the first to move out from Africa, and they have gone into many places of the world as their fossils from different regions of the world suggest. They were highly intelligent creatures, and it is envisaged as some had cranial capacities differing between 850 and 1,100 cubic centimetres. The face profile was not much protruded like inAustralopithecus,直立的人平均5英尺和10英寸高。此外，女性比男性小得多（25％）。有证据表明，他们使用火和工具来放松其功能。此外，他们已经使用筏子穿过尺寸达到海洋的水体。
What is the difference between智人和同胞?
• Sapiens is a presently surviving or thriving species while erectus was a prehistoric and extinct species.
• The cranial capacity is higher in the modern man compared to erectus.
• The face profile of the sapiens is not as protruded as in erectus.
• The skin of the erectus would have had more hair cover than in the humans.
• Sapiens is the human, whereas erectus was a human-like or hominid species.
• The sexual dimorphism was more pronounced in erectus man than in the modern man.
