Australopithecus africanus

we different from other species. Science brings us to new knowledge of how humans evolved in this world and the transition of apes to humans. The Human family tree starts from the Ardipithecus groups about 6 million years ago, the next one is Australopithecus group is about 4 million ago, the third one is paratroops group is about 3 million years ago and the last one is the homo groups is about 1 million years ago. Ardipithecus kaddaba was discovered in Ethiopia in 1997 by a…

the earliest best described hominid remains. The Australopithecus has many species such as Africanus and Afarensis through the findings of Lucy Dikita baby and the laetoli footprints. The Australopithecus Afarensis was discovered to be ape like where its upper body had curved features which adapted it for climbing. Moreover, it was also full erect hominid as indicated by the position of its hips, pelvic, lower limb bones and knees. The Africanus had the cranial capacity of 450cc weighing on…

Charles Darwin is a scientist that came up with the theory of natural selection to explain variation and evolution. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype (Zimmer&Emlen, 2013). This means that in an environment where the condition is constantly changing, species that stay in that environment and use it as their habitat adapt to the changes of the environment to survive the changes and their off springs are also able to…

Introduction: Evolution the change over a period of time is important because it demonstrates scientist the need of our ancestors for a certain body part that humans do not need which are called vestigial structure. One of the main evidence regarding evolution is fossils. Fossils are mostly used to determine structure similar animals have that humans have in order to draw conclusions. Another evidence is blood which generally shows similarity in the dna of two different mammals. The purpose…

Evolution is the change in a period over time. Scientist use evidence of evolution to prove that there was a change in organisms over time. If the evidence is present, scientist would come up with theories that are reasonable enough to have support from the pre- historic time frame. The lab is to show the people how living things came to be in the present day. Including how fossils as evidence explain why there maybe certain functions were used in the early stage of an organism. Hypothesis: If…

Even in the skull fossils ranging from Australopithecus africanus to modern day humans mentioned earlier, the skull of Homo neanderthalensis is nowhere to be found. I think it is important to include Neanderthals because changes to their skeleton may have been the result of changes in the Earth’s climate…

A major hallmark in the evolution of the hominid species is the modification in the size of the brain. The available fossil record is however incomplete and interpretation is often difficult. The supposed dominance of homo erectus species of hominids is generally credited to the proportions of their brain, that has evolved over the course of their evolutionary history. Direct evidence supporting the changes in the brain can only be obtained from the hominid fossil record, and by studying the…

has no retro- molar space, showing the diet consists of softer foods that require less chewing. It is a house- shaped skull, tall but not wide. This is the youngestnewest, and only current form of the skulls looked at. Cranium Ff is an Australopithecus africanus. This species has no sagittal crest, but has maxillarynostril pillars, which are hypothesized to have aided in chewing hard foods. It [Grab your reader’s attention with a great quote from the document or use this space to emphasize a…

Biological Genetics and Criminal Behavior Over the of course of the years, different criminologists and scientists have tried to understand the reasons and origins of crime and deviant behavior. What makes a person commit the most atrocious and heinous crimes? This is a question many people try to understand. Many factors affect the actions of these criminals, from biological factors to psychological issues. The big debate among these studies is whether such criminal behaviors are inherited…
