It was first officially recorded by Charles Darwin in his book “On the Origin of Species.” A more common explanation of the theory is “the survival of the fittest”, meaning the species survive according to their strength, ability to adapt, and ability to reproduce. The most popular form of evolution is that humans evolved from apelike creatures. “Humans are primates. Physical and genetic similarities show that the modern human species, Homo sapiens, have a very close relationship to another group of primate species, the apes” (Smithsonian National Museum). Thousands of fossils have been found and studied to see the change in brain and body size from the beginning of the human species which have had many similarities to apes (Smithsonian National Museum).
BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different. (Own knowledge, Source D) Bipedalism is unique to humans and it is known to be one of the earliest developments in hominids.
The use of chimpanzees, orangutans, and gorillas is also banned. The majority of research is conducted on rodents, with a smaller percentage using fish, reptiles, and birds. A very small percentage is conducted in larger mammals. According to Hendrick et al. (1996), the exact percentages for animals used in the UK in 2004 were: 84% Rats, mice and other rodents.
Around 2.5 million years ago, the first humans began to appear. They were more sophisticated and developed than that of the great ape family. Since this evolution, both our ancestors and modern humans have felt a yearning to share personal stories. In the preface of The Storytelling Animal, Jonathan Gottschall touches on this subject by contradicting that if monkeys were left in a room with a computer they would eventually write Hamlet word for word. The human mind is obsessed with stories and the imaginative realm that it is connected to.
According to the theory of evolution, humans are the descendents of animals and simply evolved from their more basic state. In the case of humans, it is believed they are the descendants of ancient primates. This ideology raises the question of what the true difference is between animals and modern humans. This debate on what makes a human being a human has raged for decades and will most likely continue for many more. Despite this, while humans share many characteristics with animals, they are also fundamentally different from them.
The Taung Child is the fossilised skull of a young Australopithecus africanus. When this 3 year child's skull was found in 1924, it was one of the first early human fossils to be found in South Africa. It was discovered by Raymond Dart through a local quarrymen. The Taung Child’s first molars had only just begun to rupture through the gum suggesting that the fossilized jaw belongs to a child. Upon closer inspection of the hominid’s dental development, crown formation, and root length suggest the child’s age was 3.3 years at death.
When brought to attention of Robert Brom, the partial mandible and teeth served as a holotype of Paranthropus Robustus. Further information on Paranthropus: All species of Paranthropus were bipedal, and many lived in conjunction with the species of the genus Homo. Paranthropus first appeared approximately 2.7 million years ago. Most species of Paranthropus had a brain about 40 percent of the size of a modern human. There was some size variation between the different species of Paranthropus, but most stood at about 1.3-1.4 m tall.
Brown Bears are omnivorous. So, brown bears eat plants and animals that are available to be eaten. The habitat they live in and what season it is, decides what the brown bears will eat. They like to eat grass, seeds, bulbs, wild berries, leaves, and tubers. Also, brown bears eat insects like termite nests,
The bessbug weighed 1.76 grams. The bessbug and the tin combined weighed a total of 2.94 grams. The bess bug took a total of 1 minute and 42 seconds to reach 6 centimeters without any weights. The bessbug took a total of 3 minutes and 29 seconds to reach a distance of 6 cm with five weights on it. The bees bug took a total of 4 minutes and 7 seconds to reach centimeters with 8 weights.
Wrangham proposes that dietary changes are the main reason for the biological separation between apes and humans. Evolution takes hundreds of thousands of years to drastically show change, so by searching for evolutionary advances, scientists discovered a main reason why animals, as a whole, experience change. After several years of hearing “we are what we eat," science has come to show that: “animals are superbly adapted to their diets, and over evolutionary time the tight fit between food and anatomy is driven by food rather
