Some people do not even have the knowledge about the ecosystem and how it affects the world we live in, and then there are those people that just do not care about the ecosystem. An ecosystem is a community of animals, people, and plants that interact with one another and their physical environment. One type of ecosystem that we take…

It spans from 571 million years ago to the present day. The Phanerozoic eon is made up of 3 major eras, being the Paleozoic era, the Mesozoic era and the Cenozoic era. Another term used to describe this eon is "The creation of visible life." Although the first actual signs of life took place in the late Archeon eon of the Precambrian times, the major evolution, development and expansion…

knows somebody with it, someone who's beaten it, or somebody who's died from it. If you haven't figured out what's being talked about alright, it's cancer. Cancer is something present in everyday life, even the dinosaurs had cancer way back in the mesozoic era. Cancer has been around since the beginning of time, approximately 65 million years ago. With all the advancements of medical science made in the 21st century it presents a valid question, why haven't scientists discovered a cure for…

The notochord is the defining structure of the chordates, and has essential roles in vertebrate development. It is a flexible, rod-shaped structure that is in the embryonic stage of all chordates. It gives the skeletal support and is found in between the digestive tube and nerve cord. In some animal chordates lifetimes it is the main axial support in the body. The dorsal hollow nerve cord is the only feature unique to all chordates. It is located at the top of the animal, above the notochord.…

In the Black Hills National Forest of South Dakota, Mount Rushmore, a large granite peak was dedicated in 1925 to be sculpted into a monument. That monument today is one of the most visited monuments in the United States. Mount Rushmore is a staple of the United States. On it, it has the faces of four of the most important Presidents of the United States. According to the Sculptor Gutzon Borglum “The purpose of the memorial is to communicate the founding, expansion, preservation, and unification…

Gondwana is an ancient supercontinent that existed around 500 million years ago. In fact, Gondwana broke up and eventually created the continents we know today. These continents are known as Africa, South America, Australia, Antarctica, the Arabian Peninsula, and the Indian subcontinent. Just because Gondwana eventually created the continents we know today, does not mean that these continents will stay the same forever. Eventually, there will be different arrangements in an extensive history…

important evolutionary event in each of those eras. Paleozoic The big incident of this era is the Cambrian explosion that happened 540 million years ago. Mesozoic Angiosperms were diversified during this era Cenozoic Mammals increase in size 2. Define/explain the following terms: Ediacaran, diagenesis, stromatolite, permineralized, Cambrian explosion,…

Did you know that some dinosaurs had wings and feather but they didn’t have any use for flight? According to “Raptors: The Bird-like Dinosaurs of Mesozoic Era” by Bob Strauss, Over 70 million years ago, there was a family of feathered dinosaurs called Raptors. Raptors were feathered Theropods that varied in size from no bigger than a large chicken, to exceeding the height of a full grown man. The time the Raptors lived mainly centered around 65-90 million years ago in the Cretaceous era. A…

Recombinant DNA is genetically engineered DNA that is formed by splicing fragments of DNA. Organismal cloning is the artificial creation of a new organism that is genetically identical to its counterpart. DNA cloning is a recombinant DNA technique where cDNAs and fragments of genomic DNA are inserted into a cloning vector and maintained during growth of the host cells. Vector is an agent that transfers genetic material into a cell or organism. Restriction enzymes are bacterial enzymes that find…

Imagine if after 6 million years of existing on earth, the entire human race died out by the year 3320. Within a mere 1000 years’ all of humanity would be wiped from existence. This was the case with the dinosaurs and many other species living in the Mesozoic-Cenozoic period. 65 million years ago a meteorite roughly 10 km across hit the earth’s surface, and the impact would be a catalyst to the extinction of 75% of the species living on earth at the time, including the dinosaurs. The impact of…
