Our ancient proteins support one hypothesis that the progressive loss of uricase activity allowed our ancestors to readily accumulate fat via the metabolism of fructose from fruits. Investigate what defines a hominin and how much we modern humans have in common with other human species, as well as what sets us apart. This adaptation may have provided our ancestors with an advantage when the energy-rich rainforests of Europe and Asia were displaced by temperate forests by the end of the Oligocene.
First, the family likeness the chimpanzees struggle for status, vocalise, communicate, play politics, use subterfuge, show aggression, reject outsiders, groom and support each other, betray each other and resort to violence or sexual bribery to get their way. Chimpanzees display awareness of self, ability to reason, and a grasp of numbers. Curiously, uricase is not functional in some organisms despite its role in converting highly insoluble uric acid into 5-hydroxyisourate. Of particular interest is the observation that apes, including humans, cannot oxidize uric acid, and it appears that multiple, independent evolutionary events led to the silencing or pseudogenization of the uricase gene in ancestral apes.
Paleoanthropology is the scientific study of human evolution. Paleoanthropology is a subfield of anthropology, the study of human culture, society, and biology. The field involves an understanding of the similarities and differences between humans and other species in their genes, body form, physiology, and behavior. Paleoanthropologists search for the roots of human physical traits and behavior. They seek to discover how evolution has shaped the potentials, tendencies, and limitations of all people. For many people, paleoanthropology is an exciting scientific field because it investigates the origin, over millions of years, of the universal and defining traits of our species.
Parents pass adaptive genetic changes to their offspring, and ultimately these changes become common throughout a population. As a result, the offspring inherit those genetic characteristics that enhance their chances of survival and ability to give birth, which may work well until the environment changes. Over time, genetic change can alter a species’ overall way of life, such as what it eats, how it grows, and where it can live. Human evolution took place as new genetic variations in early ancestor populations favored new abilities to adapt to environmental change and so altered the human way of life. However, some people find the concept of human evolution troubling because it can seem not to fit with religious and other traditional beliefs about how people, other living things, and the world came to be.
Nevertheless, many people have come to reconcile their beliefs with scientific evidence. Various arguments have been made to suggest why natural selection would allow the accumulation of uric acid despite the physiological consequences of crystallized monosodium urate acutely causing liver/kidney damage or chronically causing issues. Chimpanzees are opportunistic omnivores that also make and use tools for gain, and groups of chimpanzees in the wild have separate traditions, practices, and ways of doing things that they pass down the generations. That is, chimpanzees have a culture.
Both chimpanzees and humans have a genetic kinship so close that they share almost 99% of their DNA. As such, the medical community has a strong interest in developing a recombinant “human-like” uricase to treat gout, prevent tumor lysis syndrome, and control hyperuricemia in general. The difficulties in developing a therapeutic uricase are many-fold but mostly rely on a compromise between activity, stability, and immunoreactivity in human patients. A recently Food and Drug Administration-approved uricase consists of a combination of pig enzymes. I have spoken to various friends and family, and the consensus I have now arrived at is that actually, most people have a very poor understanding of the origins of our species.
I am not including Young Earth Creationists in this description, as their ideologies as a belief system is one of complete ignorance about anything that happens in the natural world, or those who decide to form their own interpretations of the book of Genesis, based upon reinterpreting what it could have meant as a rhetorical parable in today’s society, to appease and conform to both conflicting parties of thought. Our ancient proteins support one hypothesis that the progressive loss of uricase activity allowed our ancestors to readily accumulate fat via the metabolism of fructose from fruits Those who understand that we as a species evolved from another species, broadly know that humans evolved from a tree of hominids prior to our genus being formed.
