2.1 A transgression is when sea level rises. There would be deepening upwards and coarse grained rocks as you go up. 2.2 A regression is when sea level drops. There would be shallowing upwards and fine grained rocks as you go up. 2.3 The fossils at Snyder Hill were/weren’t alive during a regression. 2.4 An epeiric sea is a shallow sea that spreads onto land or continental shelf and partly bounded. 2.5 The fossils at Snyder Hill weren’t alive in an epeiric sea setting.
The Riversleigh fossil site is a part of the Boodjamulla National Park. The site was World Heritage listed in 1994. The fossil record of Riversleigh's habitats have greatly strengthened our understanding of evolution, origins, and the history of organisms. Many of the most abnormal and phenomenal organisms in the Australian fossil record have been discovered at the site. The sight contained about 30,000 footprints from a stampede involving nearly 200 dinosaurs. It sits on the south-western boundary of the Territory of the Waanyi Aboriginal clan. Riversleigh contains a collection of many fossils from around ten to thirty million years ago. Its record of mammal evolution spans of twenty million years in length at least. The fossils of thousands
In site one there was a high proportion of very unspherical rocks. According to this the hypothesis is right, in site two there is a lot more smother rocks medium sized and in site 3 there are very small pebbles which are very smooth and spherical. The pebbles get smoother and rounder while it goes downstream. Due to us only taking about 10 rocks our result may have been not right as there were some pebbles which were largely over sized. Most of the other load is dissolved by solution such as limestone and chalk
A Divergent boundary- continental plates is where two continental plates move away from each other and cause a giant dip in the ground that goes down under the surface of the Earth. The Rio Grande is a rift valley in Colorado and runs down into Mexico through New Mexico and a small part of Texas.
Based on Chapter ten from the textbook, there are seven distinct differences of a bipedal hominin like us humans, and a quadrupedal pongid, such as a gorilla (Larsen, 2014). One of the seven steps include the length of the leg, shown in humans to be long which gives us proficiency when striding or running unlike apes that have long arms for climbing on trees. A second step is the opposable big toe found only in apes that give them the capability to take hold of objects and walk. A third step of the seven is the position of the foramen magnum, which in humans is on the bottom of the skull while in apes it is in a posterior position. Overall, the difference is found in that the human head rests on top of the body while the ape head sits in the front. Lastly, a fourth step is the shape of the spine. Humans have an S-shape and apes have an almost C-shaped. Humans have numerous curves to assist in maintaining balance when standing up.
The skeletal characteristics of these hominines suggest that their mode of locomotion was likely a cross between occasional bipedalism and obligate bipedalism. From the reading we have learned that obligate bipedalism is bipedal locomotion that is practiced all of the time while occasional bipedalism is bipedalism that is practiced on occasion. The ratio of arm length to leg length (longer arms) suggests that they did spend time climbing trees, however the cranial and post cranial traits of these fossils suggest that they spent much of their time on the ground and likely ambulating bipedally combined with a variation of upright walking and knuckle walking. This is evidenced by two factors: the fact the foramen magnum of the skull is centrally located, and the ratio of arm to leg length. In creatures with bipedal ambulation, the foramen magnum is located in the center of the base of the skull to keep the head aligned over the center of gravity of the creature. If the fossils were walking primarily with their knuckles, the
Understanding the criminal behavior system and crime typologies that the book demonstrates; it is kind of hard to distinguish what type of serial killer Robert Durst is. Judging from the book examples of different type of serial killers, I would have to say Robert Durst is a hybrid serial killer. While some of his actions from the video series, “The Jinx”, lead me to feel as if he was an expedience killer who wants to protect themselves from a perceived threat as the book states. Some of Durst’s actions also lead me to believe he was a mission killer, who had a vision for killing someone. None of his victims seemed as if they were some random act of murder. I feel as if he had a mission to kill all of them.; one reason making me suspect
After finding some skeletal remains, the police have provided a list of three missing persons, Kim Lee, Theresa Woods and Jonathan Parker. While spending multiple days in the lab, plenty of information was collected to help with the identification of the bones, such as the sex of the victim, the age of the victim and the approximate height and race of the victim. This data was compiled to draw a conclusion and safely identify the remains.

For my second activity, I attended a meeting of Fossil Free SFSU. This organization is fighting to completely divest San Francisco State University from any connections with the fossil fuel industry. Meaning, this organization is campaigning for SFSU to eliminate all stocks, funds, bonds, etc.- anything associated to fossil fuels. I attended the meeting at a perfect time because it was sort of an introduction to what the organization is about and what they have planned for the future. It began with a quick introduction of everybody, and then we quickly went to business. We discussed and brainstormed what is needed to become a successful campaign team. I really
The extent to which tectonic processes represent a hazard depends upon when and where they are experienced (40)
By 0.6 Mya, H. heidelbergensis appeared. Likely an ancestor of our own species, their fossils have been found with the remnants of large, butchered animals and hand axes -- suggesting a good degree of tool usage. It is unknown whether or not they actively hunted the large animals that they hunted, but the prolifacy of these butchering sites would suggest that Heidelbergensis was able to have consistent access to these large carcasses. Examination of fossilized hyoid bones in Heidelbergensis indicates that they were also capable of making the nuanced sounds required for speech (Martínez I, et. al.). Their easy access to food and fire probably came in handy during the Kansan glacial period, which lasted from 0.46 to 0.30 Mya. It was during this icy period that the lineages of Homo sapiens and Homo neanderthalensis finally split from that of H. heidelbergensis and begin to truly hunt for their food.
Subduction is what occurs when two tectonic plates collide and one plate slips under the other tectonic plate. When this happens the bottom tectonic plate fall into the mantle of the earth and be melted to make room for new tectonic plates.
According to our lecture notes, the Renaissance era was considered as the rebirth of contemporary music. The Renaissance era was highly influenced by culture, art, and science. It was a time period where people based their knowledge on science rather than the church. Giovanni Palestrina was one of the most famous composers who came out of the Renaissance era. His style of music brought a new light to traditional church music. He changed the culture on the way sacred was written. He abandoned the old polyphonic composition, and started writing music based on free style and using high voices.
There have been many human fossils found in China, from more than 70 different sites, in fact. They all have common features and demonstrate the gradual change in them, representing gene flow. These fossils found are both Homo erectus and Homo sapiens. There are some elements in fossil skulls found in China, that gear more towards a Neandertal lineage. This indicates gene flow between Neandertals in the West, and those fossils found in the East. In 1998, Xinzhi Wu suggested a hypothesis, that with this evidence, there is continuance with hybridization for human evolution in China. Though modern humans of East Asia might have originated in China, there have also been links that some nonhuman primates are from China. However, additional findings
The combination of these and other trends was an estimated average sea-level increase of 1.5mm per year between 1961 and 2003, which reached 2.4mm per year in the decade from 1993 to 2003. The decades prior to this trend showed only minor fluctuations in sea-level, suggesting that the current rate exceeds what could be caused by natural cycles. While the exact impact of rising oceans is difficult to determine, it is certain that the consequences will include some degree of flooding, integration of salt water into water tables, and a loss of land due to coastal erosion and submersion.6
