Extract of sample "Systematics and Reconstructing Phylogeny"

4 April Systematics and Reconstructing Phylogeny Systematics is the scientific study of how organisms are diverse along with their evolutionary relationships and origin. After scientific studying of organisms is done, taxonomy is used to classify, name and describe organisms. Classification is the gouping of the organisms by their similarities. The reason why it is done is to reveal their historical relationships, to avail universally recognized names of the organisms by using one language which ensures consistency. Binomial nomenclature is a two name naming system used to scientifically name organisms. The first name is usually the genus name and the second name is usually the specific name. Species are classified into levels based on the hierarchical system beginning with domain, kingdom, phylum, class, order, family genus and species (Boaz, 1 – 7).
Evolutionary phylogeny is the evolutionary history of a group of organisms derived from a common ancestor. There are three groups; monophyletic taxon which has a common ancestor and all of its descendants, paraphyletic taxon which has a common ancestor but not all of its descendants and polyphyletic taxon which has a group of species with different common ancestors. It misrepresents evolutionary relationships. Clades are true evolutionary relationships depicted by monophyletic groups. Parsimony is used to assess alternate phylogenetic hypotheses. Systematics has a future in molecular systematic which determines evolutionary relationships by comparison of macromolecules like ribosomal RNAs and mitochondrial RNA, powerful analysis computers and DNA barcoding. For macromolecules, molecular clocks are used to estimate time of divergence through differences in proteins. DNA barcoding is efficient in varied geographical settings, and in varied taxonomic groups. It has a 99.99% resolution (Boaz, 7 – 25).
In attending this lecture, I realized that my personal ability to follow and take notes had improved and I could take notes faster and comprehensively with my concentration levels been consistent for much of the lecture. I chose to attend this lecture as it is related to my field of study which is microbiology and I have an interest in learning more about the nature of the courses I shall undertake in my graduate program. The concepts taught in this lecture are related to my field of study through their assessments of organism classification. I already knew of the binomial system of naming organisms before attending the lecture. However, I obtained new information like systematic, evolutionary phylogeny, clades and DNA barcoding. This assignment was very important to my academic goals in that it created in me a sense of expectancy, expectancy to learn and comprehend new concepts which shall make it easier for me to comprehend them in future classes.

Impact of recently discovered hominins on the understanding of human phylogeny and biology

... Impact of recently discovered hominins on the understanding of human phylogeny and biology The discovery of Australopithecus sediba and Homo floresiensis offer us clues to an important transition in our evolution. What we learn from these two discoveries is that about 6 millions year ago, when our ancestors began spending more time walking upright or in twos, their descendants evolved in various species, which have come to be referred to as hominids. For around 3.5 million years we are told that all hominids had the same basic kind of body whose characteristic included; a chimp-sized brain, elongated arms with curved fingers, a snout-like mouth and short legs that enable them to walk slowly on the ground. Scientists have called... scattered...

... remain largely unknown despite the fact that new trends of triploblast systematics are emerging which provides a clear picture of the lineage. According to previously done classifications, these basal metazoan organism have been put in different relationships using several markers except one relationship; monophyly. Earlier analyses of the basal metazoans (sponges, placozoans, cnidarians and ctenophores) have almost unanimously agreed that cnidarians and ctenophores have more close ties or relations with triploblasts than they have with the sponges (poriferans) (Hooper and Willenz 11). In traditional phylogenetic schemes the ACANTHOCEPHALA, ENTOPROCTA, GASTROTRICHA, GNATHOSTOMULIDA, KINORHYNCHA, NEMATODA, NEMATOMORPHA, PRIAPULIDA...

Scientific paper about reconstructing 3D models of buildings

... 3 D Modeling for Reconstructing Buildings from an Internet Photo Perspectives Introduction There are billions of photos in our World Wide Web. By far this is the largest photo collection ever assembled. Using this photo collection, it is possible come up with solutions such as 3D modeling, visualization, and localization for world sites among several other applications. To date, the myriad of opportunities that internet photos bring are hugely untapped. This owns to the fact that most of these images are in a form that is not amenable to processing. Most researchers who have attempted to work with this resource using conventional techniques are faced with countless problems. First, most of it is unorganized, uncalibrated, have... to...

The Phylogeny of Hominids from the Australopithecus up to the Homo

...Phylogenetic Rate Shifts in Feeding Time during the Evolution of Homo Introduction The study of the phylogeny of hominids from the Australopithecus up to the Homo sapiens has been made for a long time and is still continuing to be made with new discoveries being made and especially concerning the anatomy of these hominids. Explanations of the anatomical changes that have taken place on the hominids and how these changes have contributed to the present man are the subject of discussion. The article “Phylogenetic rate shifts in feeding time during the evolution of Homo” is based on research carried out by researchers from Harvard University which discovers that the hominids starting from the Homo erectus till Homo sapiens...

Does ontogeny recapitulate phylogeny

...Does Ontogeny Recapitulate Phylogeny? Before we can discuss the question “does ontogeny recapitulate phylogeny?”, we must first understand the two differing theories that comprise that query. What exactly is Ontogeny? How is it similar to Phylogeny? What makes the two theories of development different from one another? This paper serves to explain the difference between the two theories aside from attempting to explain that the Ontology Recapitulate Phylogeny (ORP Theory) is false through direct explanations from various authoritative sources. To begin, allow me to define the theory behind Ontogeny. Ontogeny is the scientific belief pertaining to the development of...

A review of Kim Anderson's Book: A Recognition of Being: Reconstructing Native Womanhood

...College: Book review: A Recognition of Being: Reconstructing Native Womanhood by Kim Anderson Kim Anderson’s book, A Recognition of Being: Reconstructing Native Womanhood, traces the life of aboriginal womanhood from the ancestral times to modern times. The book’s title encompasses the thoughts and reflections of the book as it draws a comparison of what an aboriginal woman was like and what current woman looks like. The aboriginal women had great powers and controlled a great deal of important resources like food, which was considered the most important resource and wealth by then. Anderson argues that most of the societies were matrilocal, where the men were controlled by women. Consequently, marriage...

Reconstructing gender

...Reconstructing Gender Reconstructing Gender Judith Lorber introduces her article by first looking at the fact that to the common lay person, gender is a binary option where one is said to belong to either of the two commonly known genders; male and female. However, she explains that gender is something that is produced by the human interaction and perception (Disch, 1997). She says that people do not realize that gender, both that the chromosome and that the social levels is not a binary option. This is very true. Recent events where a lot of people have decided to change their gender indicate that gender is more than just a binary opinion caused by chromosome. Although chromosomes do play a certain role in gender development... Gender...

Reconstructing gender

...Reconstructing Gender Men and women possess differing uses of emotion and communication skills. Unlikemen, women are more polite, speak more, are hesitant/indecisive, ask a lot of questions and they are often cooperative. On the other hand, men seldom talk about their emotions, insult one another frequently, interrupt more, are commanding and they mostly talk about sports and women. Consequently, it’s a truism that women and men don’t talk or communicate in a similar way (McGraw-Hill, 2003). These differences gave rise to the often popular phrase ‘men are from mars and women are from Venus’. The gulf found between men and women emanates from nature rather than nurture. As such, the two sexes covey their messages...
