Evolution

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…

The evolution in mammals have passed through many stages since their synapsid ancestors first appearance in Carnivorous period between 320 to 315 years ago All mammals are related deeply in their bones and today’s mammals are one of the mammal lineages that survived. Scientific evidence suggests that Otters have been on Earth from the past 23 million years and present day’s Otter evolved about 7 millions years ago. Otters have gone through many adaptations and scientists believe that Otters…

day you decide find out that all you can eat for the rest of your life is Cheetos. One day some freak accident occurs and the last Cheeto plant is destroyed and now you have nothing to eat. Sure, somehow you could evolve to eat something else, but evolution takes a lot of time (time you don’t have). If you ate things other than just Cheetos this would not impact you as much. This is an exaggeration and an oversimplification of a reason for biodiversity. Biodiversity allows for a more stable…

other ape species. Tracing the evolutionary history through fossil evidence explains how early hominids evolved to become today’s most prolific primate species. The goal of this paper is to discuss the physical characteristics that indicate the evolution of bipedalism and large brain size in the hominid line. To achieve this I will address the anatomical differences between humans and apes that make bipedalism efficient form of locomotion, the increase of brain size, and which of these…

The evolution of influenza can happen in a pig which is suitable for a virus to evolve. Within the pig’s stomach, the virus can run into another form of influenza and create a new and maybe a better version of influenza that is deadlier. That means that this version could be immune to certain medicine. The battle within the human or animal body is an ever-recurring fight and not succumbing to influenza. The fight for survival is constant from lack of resources to sickness and disease. When two…

Natural selection is when stronger organisms adapt to their environment and have more children. First is variation- different, then selection when the most favourable survive and breed more. Inheritance when offspring get favourable traits. Time- Evolutionary change- few gen Speciation- thousands of years The likeness and the variation in comparative anatomy is different in the anatomy of species. A noteworthy issue in deciding evolutionary connections in view of near life structures…

traits would have more of a likelihood to live, and then breed more offspring. Slowly, more and more of the species with the superior traits will survive and multiply. But what is it that gives these species the better survival trait, and allows evolution to occur? The answer is, genetic variation. Each individual has different genotypes that make up their structure and infrastructure. This includes physical features, behaviors, and even the abilities of an individual on the molecular and…

How did the life of this human race begin on this grateful planet? People have grown over time. Evolution is one of the most controversial topics to earn about. People must not be forced to be taught evolution. Humans must be entitled to their own beliefs. If they cannot believe what they know is right, then it will cause severe controversy. Cleary, the topic of evolution is nothing but fake arguments. The horrible teaching of how humans evolved from an ancient prehistoric beast, is corrupting…

Evolution has received mostly negative feedback from society, especially from non-scientists. Perhaps, evolution is controversial because it speaks to the beginning of humanity. Controversy originated from individuals’ religious backgrounds and faith in a higher being but they do not consider the definition of evolution. Noted by David Jacobs—Professor of Animal Evolution and Systematics at the University of Cape Town, non-scientists believe evolution states that human evolved from baboons.…

Anton from New York University, and Leslie Aiello from the Wenner-Gren Foundation— determined that the characteristics: bipedal gait, body size, and delayed growth and development for the kids, of modern humans may not have evolved all at once, but evolution was more of a “patchwork” adapting to fluctuating wet and arid conditions in Africa. They came to this conclusion based on their work with fossilized bones of two early human species, Homo rudolfensis and Homo habilis. The scientists found…
