Most members of the kingdom Fungi lack flagella; the structures are completely absent in all stages of their life cycle. The only

By using DNA sequencing software and using comparative DNA alignment programs, scientists can piece together where the differences and similarities align and the percentage of identical DNA between two species. Another method of classifying these gene-swapping organisms is to alter the method of vertical genomics and shift to a new form of lateral genomics (Koonin et al. 2001). A method using vertical, linear genomics alone will not provide enough resources to clearly assign an organism to a taxonomic group. Also, scientists can look at gene loss over time as a method to group these organisms (Koonin et al. 2001). If scientists would rather stick with similarities to define a taxonomic group, the use of genomic instruments can provide a better picture of which genes are highly conserved between organisms of the same group (Doolittle 1999). Researchers have begun to employ this method as the means for best completing a phylogenetic tree. Using alignments of single copy genes conserved in the genome allows for scientists to achieve that vertical pattern of phylogeny that can be lost when focusing on the amount of transferred genes between groups (Lang et al. 2013).

1. Did the construction of the phylogenetic tree based on the 14 living Caminalcules change the way you would group Caminalcules species in your taxonomic classification (chart)? What does this suggest about classification based on strictly of similarity versus evolutionary relationship?

It was an ordinary winter day in the city of Lynn, Massachusetts. As people headed to work and school they looked forward to the adventures the weekend would bring the next day. However, not so far away, Henry Rosario and his wife, Wendy Contreras, waited anxiously in their apartment knowing that the moment that would change their lives forever was near. “As my first daughter it was very painful, scary, and anxious” (Contreras interview). After waiting for what seemed like forever, they decided to go to Salem Hospital. Once they arrived, however, they were told by the doctor that she was not was not ready to deliver yet and was sent back home. At home, Wendy paced around the living room in agony waiting for the moment to come so she could get

The first known ancestor of the horse lived around 55 million years ago. This dog-sized animal was called the Hyracotherium, and the fossils were found in North America. This animal is said to look nothing like a horse, instead it had dog-like characteristics such as an arched back, short snout, and long tail.

Evolution is a mysterious topic, as there is just so much evidence that has been found by many people throughout history. The first person to spread the idea of evolution was Charles Darwin. He helped to spread the idea of evolution to others such as Gregor Mendel, and helped many others to accept the findings of Boucher de Perthes. Evolution is defined by the changes of organisms throughout time to better the survival rate of said group of organisms.(definitions, 2009) The generations of organisms therefore evolve through time as the changes occur. There are many pieces of evidence such as, analogous and homologous structures in organisms, cladograms, the order of appearance of structures during embryological development, and fossil records. Evidence of evolution at it’s finest.

Despite these concurring viewpoints, there are fundamental differences between these perspectives. The medical/disease perspective focuses on the costs of early stressful experiences, asserting that exposure to early life adversity disrupts normal development, causing dysregulations in biological systems (Ellis & Del Giudice, 2014). As outlined by Del Giudice and Ellis (2016), research from this perspective generally focuses on unfavorable health outcomes associated with early stress exposure, such as reduced performance on intelligence tests and greater prevalence of psychopathology. The evolutionary perspective, in contrast, extends the understanding of epigenetically-based developmental processes by examining the benefits of stress responsivity and its orchestration of adaptive developmental patterns. According to the ACM, organisms have calibrated their systems via environmental cues to adapt physiological and behavioral systems to their current and future environments (Del Giudice & Ellis, 2016). Therefore, despite potential impairments/costs, there should also be adaptations; for example, as discussed by Ellis & Del Giudice (2014), adolescents

The optional final exam will consist of five of the following essay questions.  Each essay will be worth five points.  The final will be averaged with your other four grades.  There will be a follow-up post on whether you should take the final exam, but we wanted to get the essay prompts out to you as soon as possible.

In an attempt to find a correct phylogenetic tree, our group has found that Phylogenetic tree C shows a significant lineage. After researching, Phylogenetic Tree C seems to be an accurate depiction of hominid evolution. It shows a clear line of lineage that begins with the common ancestor A. Afarensis. To explain how the hominids connected in the lineage, our group decided to compare the skulls’ cranium width and length of braincase. We concluded that over millions of years, the width of the cranium of the hominids have increased, along with the length of braincases. Our explanation matched up with tree C respectively. The order of the width of craniums recorded are: A. Afarensis (80 mm), A. Boisei (80 mm), A. Africanus (85 mm), H. Habilis (98 mm), H. Erectus (108 mm), H. Heidelbergensis (122 mm), H. Neanderthalensis (128 mm), and H. Sapien

Out of all of Well’s critiques for evolution, the one I found most compelling was Darwin’s tree of life. It honestly was very hard for me to pick an argument that I thought was compelling, because all of the arguments have far too many holes in them to seem realistic to me. I may have a biased view, since I am a Christian, but this argument of a common ancestor seemed like the most viable of the arguments because I do think that we all come from one ancestor, except, I think we come from Adam. I do think that this argument has the most power to me because of its potential to be true. Although fossil records indicate something more similar to the Cambrian explosion stated in the book, Well’s did admit that he could not prove to Strobel that

it is a chemoorganoheterotroph, meaning that it obtains its energy from chemicals (chemotroph), uses organic substrates like lactate and acetate as electron donors (organotroph), and obtains it's carbon from organic sources (heterotroph).

Students are not sure of how they should be reading an Evolutionary tree. An evolutionary tree is a diagram that shows how species are related to each other, it also shows when certain genes become different from the other species throughout time.

I have been enrolled with Tree of Life for the past five years in order to prepare for university. Tree of Life is a member of the Association of Classical and Christian Schools since 1997 and educates more than 400 home-schooled students across Canada annually. The school utilizes the classical approach in order to help students gain important academic skills, apply critical thinking, and develop their ethical point of view.

spatial variability. Current transportation systems and thus are adopting the product of a long evolution was marked by periods of rapid changes in the new transportation technologies. After the Industrial Revolution in the 19th century, the mechanization of transport systems with the development of the steam engine technology allows setting of services networks areas. [11]
