Explain the emergence of Homo sapiens. Homo sapiens emerged
Article Review #3 The article “Ardipithecus ramidus: A New Kind of Ancestor: Ardipithecus Unveiled” written by Anna Gibbons, talks about how scientist learn many things about human evolution through artifacts of ancestors, DNA and bones. All of this helps reveals different things about our past and how we came to be. This article briefly mentions Lucy and it mainly focuses on the discovery of ardipithecus ramidus.
Henrietta Lacks was a black tobacco farmer from the south who, in 1950, at the age of 30, she was diagnosed with aggressive cervical cancer. Lacks went to John’s Hopkins medical center for treatment for her cancer. In April of 1951, she underwent surgery to remove the larger tumor on her cervix. Henrietta Lacks, died three days following the surgery. Even though Henrietta Lacks died, her cells from the tumor have lived on and have made a major impact on the biomedical community.
1. Scientists never found what makes Henrietta's cancerous cells different from other cells. 2. Her story is not important in the terms of how the cells were used, because it has no impact on it.
Henrietta Lacks is the first African American woman to have the first immortal cells. She was born August 1, 1920 and grew up in Virginia with her six siblings. Henrietta is most known for her cell line used by thousands of scientist across the world. Today people refer to her cells as HeLa cells, this is short for Henrietta Lacks. Scientist could not understand how her cells became immortal.
As written in bible, animals were created on the sixth day before humans were created on the seventh day. In the pragmatic examination and observation of scientists, there were dinosaurs long before humans appeared. Bones, habitats ,etc were all realistic evidences for the theory of dinosaurs. He also raised the point of Pangaea. Humans were all the same, however, after the breaking up of the continents, evolution happened and some people had darker skin.
The show begins with one single newscaster John Ladarola, introducing the headline news event. He introduced the headline as bad news for Obamacare as Aetna insurance giant would be pulling out of many insurance exchanges that help fund and run Obamacare. He then moved on to question, by stating “but why exactly are they pulling out”. John Ladarola then ran through some financial numbers that Aetna claims is showing they are losing over 100 million a year. With this, Aetna is claiming that it is not financially feasible to continue operating in the same manner.
Without a doubt, killer whales (Orcinus orca) are by far among the most intelligent and socially complex creatures on the planet. They live in close-knit family units each with unique social structures, hunting techniques, and even vocalization. A wild orca is a sight to behold, gracefully gliding through the waves, enjoying being the powerful, elegant creature that it is. However, some orcas are not so lucky. The captive killer whale industry is mainly monopolized by the SeaWorld corporation, which has made billions off of the exploitation of orcas and their “Shamu” shows.
In chapter 1 of the earth and its people by john the first chapter is about how we as humans came about starting from the Homo sapiens who had a more developed brain than the other type of subspecies humans that came before the Homo sapiens such as the Homo erectus or the Neanderthals who had a less developed brain. Initially the Homo sapiens were first known to come from Africa nearly 400,000 and 100,000 years ago as they evolved from being a Homo habilis and a Homo erectus. After their evolution the Homo sapiens became mostly known for being able to use their minds to do things such as make tools, hunt animals, draw paintings and speak or use some form of language. Which allowed them to form hunter-gatherer societies were the women would gather bulks of berries, nuts and plant which was the most stable source of food income that the groups could rely on.
Chapter 1 Summary: 1. Chapter one is about the starting of human life. Diamond starts the chapter off by explaining Homo erectus and how humans developed from apes to Homo sapiens. The chapter further explains how humans split off into sections of the world, by starting out in Africa and spreading to continents such as Eurasia and Australia/New Guinea. The main discussion of chapter one is how the humans developed differently between different areas of the globe, but all originated from one place.
Doris Gudino Professor Chounlamountry Political Science 1 27 July 2015 Pro-Choice Anyone? A woman has, undoubtedly, the freedom to procreate, but once a woman chooses to retreat from that freedom, a commotion arises. Abortion is a woman’s choice for many reasons. It’s her body, therefore, no one else can decide for said person.
Science has enabled us to thrive in a world where change is a must if an organism wishes to live. It has allowed for us to bend and twist the world at our feet, even having enough strength to repel the touch of death. Genetic engineering is the next scientific advancement that will stand close in the near future. It has the capability of modifying the food production process, elimination of diseases and disorders, and the guarantation of the best traits in an organism.
Most people in our society, no matter what level of education that they may have, have heard of the cloning, specifically the cloning of Dolly the lamb, and have some notions regarding the idea of cloning humans. "The successes in animal cloning suggest to some that the technology has matured sufficiently to justify its application to human cloning" (Jaenisch et al.). However, not every agrees that human cloning is a something that should be put into practice (Hoskins). There generally seem to be two basic divisions on this issue: those who find it inappropriate and unethical, and those who find it a reasonable and necessary step in the progression of scientific research (Lustig).
3. Human ancestors appear to have originated in Africa millions of years ago. Describe, in general terms, this progression over the past for human ancestors in Africa. Which group located in the south of Africa are the present day descendants of the original Homo Sapiens?
In the article First of Our Kind, Kate Wong explains why the fossils found by paleoanthropologist Lee Berger could challenge current notions about human evolution. Geologists dated the fossils to be 1.9 million-years-old which makes this species younger than Australopithecus africanus and contemporary with Homo habilis. This, along with the mix of Homo and Australopithecine traits, led Berger to the theorize that this species was a descendant of A. africanus because of its location, and ancestor to Homo ergaster because of the Homo traits. Berger 's theory would thereby toss A. afarensis and H. habilis into the junk drawer where hominid dead ends are kept.
