Oldest hominid

Thrinaxodon was one of the descendants of the survivors of the Permian extinction and serves as one of the most well and understood transitional fossils from the early Triassic; Robert Broom became famous for finding specimens of early hominids in South Africa. Archeaocete whales had nostrils on the end of their snout rather than a blowhole like modern whales and dolphins; Leigh Van Valen pointed out archeaocete whales had blunt triangular teeth similar to land dwelling, hoofed mesonychids.

family tree of the modern human so that we can fully understand are existence. Reasons why is so important to study the hominin evolution is that biologically we are the same organism with a few adaption’s throughout the different evolutions. Our oldest organism dates back as far as 7 million years ago. As we excavate and discover more cave art, artifacts, and skeletal bodies of past ancestors, we learn and realize more about

through much natural selection to be who we are now. More natural selection is also occurring now faster than ever and will in the future. All “humans” originated in Africa approximately six million years ago from Australopithecus anamensis, one of our oldest ancestors. Bipedalism was one of the first

developments over millions of years. Hominid bipedalism has evolved as a product of natural selection, a theory coined by Charles Darwin in 1859. This theory of evolution through the process of natural selection explains that some organisms are more reproductively fit than others. Therefore, these organisms are able to pass on their beneficial genes to the next generation. Essentially, traits that give certain organisms specific advantages, such as bipedalism in hominids, will be selected for in greater

According to Bergmann’s (1847) rule and Allen’s (1877) rule, animals that live in warmer climates are likely to be smaller than their counterparts in colder climates and those that live in colder climates will have a low surface area to volume ration in order to retain heat, respectively. Similarly, Allen’s rule is often used in respect to latitude rather than mean annual temperature. This is the most basic form of the rules of evolution in relation to climate; a colder climate leads to a stockier

Herto Homo Sapiens and the Questionable Origin of Man Many discoveries have been made that give more and more clues to the history of life on earth. Paleontologists find artifacts throughout the world that not only answer many questions but also raise many new ones. A topic that is still a mystery today is the origin of man. Scientists often debate over where man originated from and who some of his prehistoric relatives were. Some people think that all men are related, and that there has

What evidence shows the changing from the early hominids to the modern humans? Throughout the human evolution body parts like legs and harms have changed for the better. By the early hominids being biped, meaning they are able to stand and even walk on two feet, it helped them to be able to do more things like getting around more and help with their tool making and hunting. A lot of the fossils discovered were found in the Great Rift Valley in East Africa, which contained many different lakes

supporting her weight while walking upright. She had thigh bones that were angled inwards and a short, broad pelvis that helped keep her body upright. These are both required in order to walk efficiently on two legs. Lucy was a very early stage of hominid species that have since taken on different shapes and become more and more capable of thriving on this planet. From studying fossilized bones such as that of Lucy’s, we can pursue further studies on how greatly humans have evolved over the years.

on the planet. Human impact on the environment has increased progressively through time from the earliest hominid hunters to modern city-dwellers. A fundamental expression of early humanities ability to control the environment occurred during the birth of agriculture. While the ecological impact from this feat has allowed humanity increased control over its environment, the earliest hominids were able to survive nearly two

scientific evidence demonstrates that the physical and behavioural traits of all living humans are extremely closely related. Numerous similar and uniquely different hominid species have existed throughout evolution, leaving Homo sapiens as the only existing hominid species
