Evolution occurred over millions of years, over time humans evolved from apes to humans and many other animals did also done, like horses, mice and birds, but what does evolution mean, The Merriam-Webster Dictions 2019 defines evolution as “descent with modification from pre-existing species: cumulative hereditary change in a population of organisms over time leading to the appearance of new forms: the process by which new species or populations of living things develop from pre-existing species. forms over successive generations » Most mammals have evolved over the years, human evolution can help people understand where we came from and how much we have changed. However, evolution can show us flaws within our environment and society because, as other species have developed new technologies and lifestyles, they have not caused major changes in nature. human species. Homo erectus is a relative of homo sapiens, they lived millions of years ago. In the genus homo, we evolved and changed from species to another type of species. I'm going to look at Homo Erectus because they look more like homo sapiens than the previous homo. Homo Erectus is known to have originated in the Late Pliocene/Early Pleistocene and to have survived through almost the entire Pleistocene epoch, ranging from about 1.8 Ma to perhaps less than 100 ka (Antón, 2003) , if homo erectus survived for the duration of the era. During the Pleistocence era, they survived the Ice Age, when many animals were killed off or became extinct. The skull of H. erectus, with its low profile and average endocranial (brain) capacity of less than 1,000 cubic cm (61 cubic inches), is markedly different from that of other humans, which is smaller than modern humans like the homo sapiens can have it. a capacity of 2,000 cubic cm. Homo erectus were bipedal, meaning they woke up on two feet. This suggests that Homo erectus had larger faces, with a forward-pointing lower jaw, that Homo erectus was also well equipped to preserve moisture, this was a physiological advantage as they would have been able to travel further for a long time, had stronger and more prominent brow ridges. . They also had larger teeth than homo sapiens. Rightmire, GP (1993) and (Rightmire & Tobias, 2017). Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get the original essay Homo erectus is suggested to have lived in vegetative environments/habitats, such as forests and shrublands Reed, KE (1997). Christopher Boehm suggested that Homo Erectus was probably the first hominid to live in small familiar band societies similar to modern hunter-gatherer band societies, meaning that Homo Erectus hunted for food and lived in groups of hunter-gatherer societies. Homo Ergaster/Erectus is said to have shorter intestines than its predecessor, and furthermore, Homo sapiens has shorter intestines than Homo erectus. It is suggested that Homo erectus were adapted to eat meat due to their teeth, their teeth show that they were adapted to an omnivorous diet, which is both plant and animal (Robinson, Cummings, Jordan, & Zvelebil, 2014 ), the diet of homo erectus. Homo Erectus was good for them as it was very unlikely that they would gain excess weight, this was also due to the fact that Homo Erectus were hunter gatherers, this meant that they moved around to get food, this Whomeant that they burned fat from the meat they ate. . We have evolved since homo erectus, we continued to be hunter-gatherers for a while, we have become much more intelligent since homo erectus, this is because our skulls have developed and the brain developed over millions of years thanks to this we were able to By creating new technologies such as medicine, that created by Alexander Flemming in 1928, Homo sapiens also acquired the ability to use language, this was caused by the transformation of sound production systems (Ploog, D. (2004). Blumenbach (1969) provided the first morphology of homo sapiens. He distinguished homo sapiens from other mammals by these characteristics.se characterized by a chin, small jaws, small canines adjoining small incisors, a large cranium balanced at the top of a vertical spine, an upright posture, bipedalism, a bowl-shaped pelvic girdle, "buttocks » and a long thumb. We are therefore physically different from homo erectus. So, what is the difference between Homo Erectus and Homo Sapiens? Modern Homo sapiens live in built-up areas such as towns and villages, which is different from earlier Homo sapiens like Homo erectus who lived in areas such as grasslands, shrublands and forests Reed, KE (1997 ). Our brain size is a bit larger than that. of homo erectus, the maximum brain size of homo erectus (1,000 cubic cm) was smaller than that of homo sapiens which is a maximum of 2,000 cubic cm Rightmire, GP (1993), this advance brain allowed the development of more advanced linguistic skills of homo sapiens (Ploog, D. (2004), similarly, homo erectus also used pre-modern language to communicate with others. Hillert DG (2015 ) had larger teeth and a larger jaw, which was well suited to its diet which included meat and plant matter unlike homo sapiens which has a smaller jaw and teeth, the researchers. stated that this decrease was mainly due to changes in the dietary habits of the species These dietary changes are modern foods that are much gentler on the teeth, meaning that we do not have to use our teeth to. tearing raw meat and plant matter Emes, Y., Aybar, B. and Yalcin, S. (2011). Not much is known about the specific diseases and conditions of Homo erectus, but one of the world's leading causes of death, tuberculosis (TB), was discovered in a Homo erectus skeleton aged half a million years. Schmidt CW (2008), this tells us that Homo erectus people may have suffered from tuberculosis and this could have been a reason why some may have been killed, but as Homo erectus was the most common hominid ancient of its kind, this suggests that tuberculosis was not a mass killer at the time. This evidence that TB affected them could be a reason why some people are more susceptible to the disease, because when Homo Erectus died from TB, the TB genes could have been passed on. Homo Erectus did not have medicines and therefore could not be treated with medicines, but now it can be treated with medicines. As tuberculosis is even more prevalent in poorer and underdeveloped countries according to the World Health Organization, this shows that we still need technology to get rid of diseases and illnesses, because our evolution has not not changed the way we are able to fight and kill disease.
