Evolution has happened for millions of years, over time humans have changed from ape to human and also many other animals such as horses, mice and birds, but what does it mean evolution, The Merriam-Webster Dictions 2019 defines evolution as “descent with modification from pre-existing species: cumulative heritable change in a population of organisms over time leading to the appearance of new forms: the process by which new species or populations of beings living creatures develop from pre-existing forms through successive generations” most mammals have evolved over the years, human evolution can help people understand where we come from and how much we have changed. However, evolution can show us flaws in our environment and society because, as other species have developed new technologies and ways of living, they have not caused major changes in humankind. Homo erectus is a relative of homo sapiens, he lived millions of years ago. In the genus homo we evolved and went from one species to another type of species. I will look at Homo Erectus as they are more similar to homo sapiens than the previous homo. It is known that Homo Erectus originated in the latest Pliocene/Early Pleistocene and that it survived almost the entire Pleistocene epoch, from about 1.8 Ma to perhaps less than 100 ka (Antón, 2003), if l 'Homo Erectus survived for the entire Pleistocene period, surviving during the Ice Age, when many animals were killed or became extinct. The skull of H. erectus, with its low profile and an 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 as homo sapiens can have it. a capacity of 2,000 cubic cm. Homo erectus were bipedal, meaning they woke up on two feet. It is suggested that homo erectus had larger faces, with the lower jaw pointing forward, homo erectus were also well equipped to preserve moisture, this was a physiological advantage as they would have been able to travel for longer , they had stronger and more prominent brow bridges. They also had larger teeth than homo sapiens. Rightmire, G. P. (1993) and (Rightmire & Tobias, 2017). Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

Christopher Boehm suggested that Homo Erectus was probably the first hominid to live in small family societies similar to modern hunter-gatherer band societies; this means that Homo Erectus hunted for its own food and lived in groups of hunter-gatherer societies. Homo Ergaster/Erectus is said to have had a shorter intestine than its predecessor, furthermore Homo sapiens has a shorter intestine than Homo erectus. It is suggested that homo erectus was adapted to eating meat thanks to its teeth, which show that they were adapted to an omnivorous diet, which is composed of both plants and animals (Robinson, Cummings, Jordan, & Zvelebil, 2014), the diet of Homo Erectus was good for them as they were very unlikely to gain excessive weight, this was also due to the reason why Homo Erectus were hunter-gatherers, this meant that they moved to get food, the which means they were burning fat from the meat they consumed. We evolved from homo erectus, we continued to be hunter-gatherers for some time, we became much more intelligent from homo erectus this is because our skull developed and the brain developed over millions of years and thanks to this we arewere able to create a new technology such as medicine, the one 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. In this way he distinguished homo sapiens from other mammals by features such as a chin, small jaws, small canines adjacent to small incisors, a large braincase balanced on a vertical spine. , upright posture, bipedalism, a bowl-shaped pelvic girdle, "buttocks" and a long thumb So we are physically different from Homo erectus So what is the difference between Homo Erectus and Homo Sapiens? built-up areas such as cities and towns, this is different from earlier homo such as homo erectus who lived in areas such as grasslands, shrublands and forests Reed, KE (1997). '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, G.P. (1993), this brain progress contributed to the development of more advanced linguistic abilities in Homo sapiens (Ploog, D. (2004), similarly Homo erectus also used a pre-modern language to communicate with others. Hillert DG (2015) Homo erectus had larger teeth and larger jaws, this was well suited to their diet which included meat and plant material unlike Homo sapiens who have smaller jaws and teeth, the researchers said this decrease is mainly due to changes in the feeding habits of the species, these changes in the diet are modern foods that are much softer on the teeth, meaning you don't need to use your teeth to tear raw meat and plant material Emes, Y., Aybar, B., & Yalcin, S. (2011). Not much is known about diseases and conditions specific to Homo erectus, yet one of the world's leading causes of death, tuberculosis (TB), has been found in a skeleton. of Homo erectus half a million years old Schmidt CW (2008), this tells us that Homo erectus people may have suffered from tuberculosis and this could perhaps have been a reason why some were killed, however since Homo erectus was the longest living hominid of the genus, suggesting that tuberculosis was not a mass killer then. This evidence that tuberculosis affected them could be a reason why some people are more susceptible to the disease because when Homo Erectus died from tuberculosis, the genes may have been passed on. Homo Erectus had no medicine so it could not be treated with drugs, however today it can be treated with drugs. Since according to the World Health Organization tuberculosis is still more prevalent in poorer and underdeveloped countries, this shows that we still need technology to get rid of diseases and conditions because our evolution has not changed how we are able to fight and eliminate diseases. So sometimes evolution cannot kill or eliminate diseases, leaving them to the next species. Bibliography Antón, S.C. (2003). Natural history of homo erectus.
