The History Of Human Evolution

An aspect of biology that interests me is the evolution of humans over many hundreds of years. Human evolution began six million years ago in Africa. This has been proven countless times by evidence such as fossils of human remains which can be dated back to many million years ago. Our first ever relative was a fish that existed 400-350 MYA. It was called the Notharctus Tenebrosus and its first fossil was discovered in 187in 1870. It is linked with...

The Role Of Fire In Human Evolution

Humans have developed in many capacities that have led to our advantages and technology today. We have developed from over 3 million years ago with brain and body developments. There are six key essential concepts that have helped our species grow, including fire, language, cooking, shelter, clothing, and art. Each of these concepts is connected to each other in a way and can connect these inventions together. They are the basic ideas that we developed that are the first step...

Human Evolution And Human Origins

Abstract The fossil record supplies research with evidence of human origins, offering a crucial insight into the study of palaeoanthropology. This discipline has critically developed our understanding of human origins; however, the fossil record is sporadic and incomplete, often precluding a full assessment to the potential morphological scope of past populations. Over the past couple of decades, advances in molecular genetics have precipitated a new age for evolutionary studies in human origins. Research on DNA variation in diverse human populations...

The Significance Of Human Evolution

Introduction Evolution is the theory that is based on the idea that all species are related and gradually change overtime. Evolution is any change in the heritable traits within a population across several generations. A scientist named Charles Darwin once stated, “The love for all living creatures is the most is the most noble attribute of man” this is because Darwin was inspired by evolution. Evolution is important to this day as it is a major contributor to current scientist’s...

Darwin’s Theory Of Human Evolution

The theory of evolution by natural selection was first formulated in Darwin’s book ‘On the Origin of Species’ in 1859. This is the process that changes a species over time due to changes in heritable physical or behavioral traits. These changes allow an organism to better adapt to its environment which helps it survive and have more offspring. (than, 2018) Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from...

Gene Therapy As The Evidence Of Human Evolution Theory

Our current theory of evolution in basic terms is that all living things come from a common ancestor and that natural selection caused the adaptions that created all the different species on our planet. This is a huge claim- that everything on Earth is somehow connected. But, what evidence is there to support it? Fossils are time capsules for biologists. They are extremely solid (almost rock solid, get it?) evidence of evolution. Fossils consist of parts of deceased organisms that...

Natural Selection And Evolution

Biston betularia, commonly known as the black and white moth or pepper moths, is a good example to show how natural selection influences the features of a species. Natural selection involves four key parts consisting of variation, influence of the environment, survival of the fittest and population changes. All populations have genetic variation which can be passed on. Some variations are more favourable than others, making those individuals better suited to their environment. Individuals with more favourable variations are more...

Human Evolution: Bipedalism, Evolution Of Human Jaws And Teeth

Science Assessment – Evolution Sharing a common ancestor Comment by TERLIER, Blair: Get rid of headings now and turn into an essay. Where are your intext references?? Studies of fossils, genetics and proteins suggest a common ancestor of chimpanzees and humans from millions of years ago. Humans have undertaken millions of years’ worth of evolution and are the result of countless evolutionary deviations such as bipedalism, smaller teeth and shorter jaws, larger brains and increasingly complex forms of technology. The...

Evolution Of Homo-Sapiens: Facts Of Birth Of Humankind

·Introduction: It all started about gazillions of years ago, when something really phenomenal happened, which changed the whole scenario of possibly the only living planet in the universe, i.e. Earth. The humanity has taken birth, by no one still knows how, and created a history then. Well, it is still a mystery, how human-kind was born. Many theories have been written, explaining how it all took place, but the fact is that we are still fact less. There are no...

General Overview Of Human Evolution: Critical Analysis

All species are unique and special. Our uniquely evolved intelligence has pushed us as a species to rely on technology – something unique to human evolution. We do many things because we are the original architects behind science, engineering, and culture. From these developments, we have discovered the study of genetics, a process in which we can better understand where humans came from as a species. Genetics can help educate the connection between different peoples and give historians and anthropologists...

Positive Selection In Human Evolution

Human Evolution has become a very prevalent topic of conversation over the past number of decades, with various ideas of how humans came to be who we are today. From a time where it was once thought that humans were a very close-knit evolutionary group, to now understanding that we do in fact, derive from apes. It is now believed that our closest ancestors are those of the African apes, the chimpanzee and the gorilla. Evidence from Charles Darwin and...

Explanation of Human Development Using the Theory of Evolution

The theory of evolution can explain human development when examining biological adaptations. To begin, one adaptation that supports human development with regards to evolution is sweat glands. Sweating is a cooling mechanism that ultimately keeps the body’s internal temperature stable. The human skin is naked, has no coat of fur and is sweaty which helps one’s body cool down. The absence of sweating can cause the human body to overheat and die instantly. The humans developed the sweat glands mostly...
