Genus

findings arise complicating the picture of human evolution, but this is not the case when it comes to the picture painted by Chris Stringer in his book, Lone Survivors: How we Came to Be the Only Humans Alive. Homo. naledi, a recent addition to the Homo genus supports Stringer’s Out of Africa Theory by aligning with the three aspects of the theory: the origin, coexistence and competition of humans in Africa.…

at the bottom of the fresh water floor. The organisms are unique due to the presence of one-or two blue-green rod shaped chromatophores in the cytoplasm. The chromatophore of Paulinella shares similar characteristics with the cyanobacteria of the genus Synechococcus, such as having a thick peptidoglycan wall, and performance of binary fission similarly. Therefore, the idea of Paulinella chromatophore is thought to be an endosymbiotic cyanobacterium, that relies on survival by staying within the…

Middle Ages to the discovery of lysergic acid combined with a sample derivative to properly create LSD itself, but when does psilocybin get to show its potential once and for all? To begin with, psilocybin is found in all species belonging to the genus Psilocybe (117 species), primarily found in these plant organisms. The name Psilocybe is derived from the Greek roots “psilos” (bare) and “kube” (head), translating into a New Latin term…

Chapter One: The author grew up in Kenya, a place which developed his love of nature and all the flora and fauna within it and provided a chance for that love to grow. His parents were both passionate naturalists, especially his father. He was taught to love fossils because of his parents love for them. Because of being raised in the wild, he has always been drawn to it. When he was younger, he would sell bones to museums. This job helped him to prepare for his future specialty in…

Tsukuba. Before understanding how this mysterious single-celled organism works, it had to be given a proper scientific name. Analysis of its cellular structure and genetic profile showed that it is most closely related to organisms assigned to the genus Katablepharis. However, electron microscopy revealed certain quirky features that are not consistent with Katablepharis classification. These features include a compressed-oval cellular shape, an unmistakable crawling motion, and a feeding…

also to be able to produce milk to feed them. Mammals also have hair or fur. “Coyotes are of the genus mammalia…” Coyotes are part of the family Carnivora, and that makes the need for sharp teeth and a digestive system that can digest large quantities of meat. This would help bring back coyotes as well, even though it includes lizards and fish, it would help bring back coyotes. Coyotes are part of the genus Canis which makes them have thick fur and walk on four legs. Quadpedulism, mixed with the…

There are many levels of classification of organisms. Organisms are classified based on these groups, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Humans and most abused animals are all in the same kingdom, phylum, and class meaning that they are closely related to each other, however a life-form is mainly determined by their genus and species which is where humans and nonhuman animals differ. The Humane Society International (HSI) stated in its article titled "About Animal Testing…

contribution to drawing an educated conclusion. After performing the gram staining and observing which unknown culture was gram positive, a catalase test was performed. The catalase test allows lab workers to differentiate Staphylococci and Streptococci genus. The test was performed only on the gram-positive culture. Bacteria that respire by the use of oxygen, otherwise known as aerobic respiration, produce enzyme or “catalase”. This protects the bacteria from the harmful by-product produced…

Order Hymenoptera, the third-largest order of insects, comprises the sawflies, wasps, bees, and ants. Over 150,000 species are recognized (Janke 2), with many more remaining to be described. Many factors have led to this order’s success, through the development of wings, their immense range of behavioral adaptation, and namely: their highly complex ways of self-defense, mainly those of the biochemical and morphological nature. From the famous “cow-killer” to the range of stings of the Vespidae,…

Scientific method not only links to bigger contexts and objectives for this course, but also enhances our understanding the evolution in human populations. From race to cultural identities, scientific method greatly acknowledges the evolution of our biological adaptations and diversity. We put great emphasis on the scientific method because it never seeks for absolute, definite answers. Instead, it opens up new possibilities of stronger evidence to support the human evolution. With many…
