Human evolution is the evolutionary process leading up to the appearance of modern humans. While it began with the last common ancestor of all life‚ the topic usually covers only the evolutionary history of primates‚ in particular the genus Homo‚ and the emergence of Homo sapiens as a distinct species of hominids (or "great apes"). The study of human evolution involves many scientific disciplines‚ including physical anthropology‚ primatology‚ archaeology‚ linguistics‚ evolutionary psychology‚ embryology

Human Evolution During the evolution process from ape to man‚ it could be concluded that the biped and upright walking posture was a requirement for the emergence of human beings while the true difference between human and ape was the ability to make and use tools. Besides‚ the perfection of upright walking was the result of adapting the natural environment and the motivation for physical evolution of human. This posture positioned the head from the front to the top of body‚

Biology – Period 1A 24 November 2014 How is the Human Race Still Evolving Today? Evolution is the descent of organisms from common ancestors with the development of genetic and phenotypic changes over time that makes them more suited to the environment. However‚ with how advanced and dominant human society is compared to the rest of the world‚ many ponder whether evolution is still happening for the human race. We can see signs that we‚ as humans‚ are still evolving through the fact that we drink

Human Evolution is just a theory. Hominids began to come to life about four to five million years ago and only one will adapt to become us. Many species had to adapt to their environment or die off. The result of changes in the environment made us today. Australopithecus aferensis are one of the first hominids‚ also known as the Australopith. The Australopith had a reason why they had to stand up on two legs. Eight million years ago‚ Africa was covered with tropical rain forests. Suddenly‚ tectonic

Gertsen Skin Evolution Essay Human skin pigmentation is the product of two clines produced by natural selection to adjust levels of constitutive pigmentation to levels of UV radiation (UVR). One cline was generated by high UVR near the equator and led to the evolution of dark‚ photo protective‚ melanin-rich pigmentation. The other was produced by the requirement for UVB photons to sustain cutaneous photosynthesis of vitamin D3 in low-UVB environments‚ and resulted in the evolution of pigmented skin

EFFECTS OF CLIMATE CHANGE ON HUMAN BEINGS AND HOW YOU CAN MINIMISE THEM Ever since the past century rainfall patterns have been so unpredictable‚ temperature levels have changed drastically and natural disasters have crowded over the entire earth. Life on earth is on great danger and no doubt that the world is drifting away little by little. Time and again‚ Climate change has been the root cause of all these events. It has threatened lives of human beings‚ wild animals both

It develops gradually over time‚ meaning different levels of awareness can exist(Kai Riemer‚ Russel Haines‚ 2008). Climate change is a significant and emerging threat to public health‚ economics‚ tourism‚ and agriculture‚ and changes the way we must look at protecting vulnerable populations.

Climate Change and the Effect on Endangered Species There are many problem in this world‚ every day an anomaly is done that affect the future of this planet. As history illustrate man has always wanted to expand his borders without laying site of what horror he left behind The urge to develop and expand the society has merely brought about the distraction of this planet. A trench has been dug so far off‚ that it’s merely impossible to ride that horse once again. In the last decade machine and

Along with its anxiety-inducing effects‚ climate change also offers an interesting opportunity to consider fascinating‚ interconnected processes on Earth. The smallest to the largest components of the planet – from bacteria to volcanoes – all somehow feel the effects of a changing climate. Here are six of the most unexpected ways climate change impacts Earth Desert bacteria dies Desert soil may appear desolate and void of life‚ but it actually teems with bacteria.

Evolution of human intelligence The evolution of human intelligence refers to a set of theories that attempt to explain how human intelligence has evolved. These theories are closely tied to the evolution of the human brain and to the emergence of human language. The timeline of human evolution spans approximately 7 million years‚[citation needed] from the separation of the Pan genus until the emergence of behavioral modernity by 50‚000 years ago. The first 3 million years of this timeline
