To continue with our evolution unit, we’ll have the opportunity to view the video “Becoming Human: First Steps.” If you miss class, you can find the video on-line at:

The goal of the lab assignment is to write a summary of the video and highlight what you have learned from the information presented. Feel free to take notes during the video or review it at home as you prepare the summary. You may use other resources such as your text or valid web- based links, but these must be included in a citation section afterwards. The assignment is worth 10 points and should reflect responses to the questions above. The entire assignment should have a content range between 300-400 words. Use the word-count feature on your word-processing program to help you determine this. An assignment below the minimum content criterion will be scored accordingly and points deducted. As with any college course, proper spelling and grammar should be reviewed for each response and I will take these items into account as I score your paper. Gross negligence of proper spelling and grammar will incur a loss between 1 and 3 points to your paper, depending on the degree of spelling and grammar issues.

Please present your written, typed assignment in paragraph form and use formal writing style (e.g., proper spelling, grammar, complete sentences, etc.); use “Times New Roman” or similar font, 12-point font size, and standard, one-inch margins when typing your paper. Lastly, be sure to include your name, your student ID number (i.e., “S00xxxxxx...), the course (BIO 106L) and a title at the beginning of your paper (i.e., “Evolution Lab Assignment). If you use other resources when preparing your assignment, include those in a “Works Cited” section, using APA (or MLA) format. (It is imperative that you cite any additional resources used in the assignment, but is not essential that you cite the video for your summary as we are drawing a majority of the information from this.) If you have any questions on proper citation methods or when it is appropriate to cite another source, please ask. Remember: failure to properly cite ideas or information that are not your own will constitute plagiarism, as described in the course syllabus and college catalog.

Explanation / Answer

Million of years ago, we were aves then how would did we get from that to human? Questions are huge but at last there is answers. More than 6 mya we took that first step to separate from aves. In the shara desert, a 6mya fossils found called sahelantropus. Scientist scaring the most part of the africa for the clue of evolution. Research began in the Afar, eastern ethiopia, where million years of history brought to this surface in layers of the exposed rocks. It is hot and dangerous too. Scientist Zeresenay alemseged was searching for the fossilised ancestor, which is extremely rare. 1st thing spotted was little chick bone, but it was not the baby chimpanzee because as right side turned over he saw the more bones inside. And clues to the age of fossils came from this land. Our ancestor was Australoopithecus Afarensis (3-4mya) who walked on two legs. As our environent changes scientist believe that ancestors changes too. As the forest shrink the trait most dveloped that was bipedalism, walking on two legs. Why this trait developed? There are lot of theories like (1) they stood up to look up of the grass 2) they stood up to pick fruits from the lower branches of trees. 3) they stood up to cool more efficiently 4) most compellent hypothesis is to save their energy. Lucy was called as missing link between chimpanzees and humans.The technique called molecular clock most transforming technique. Today scientists can compare DNA from closely related species and can find how longer they go split from common ancestor. It was proved that human evolved from the chimpanzees much earlier than we thought i.e. about 6mya, Lucy was just one step before the human. Who was our first ancestor? Scientis decided to change their loocation from east africa to west africa, there they found a fossils that was 6 million years old named Sahelanthropus Tchadensis (6-7mya). Million of years ago there was upside walkers and big size of brain given complicated name like Orrorin Tugenensis (6mya) seeing as a forascence of species and multiple species probably different from each other. Ardipithecus Ramidus (4.4 mya) recognised that no major differences, Australopithecus Africanus (2.4 – 3 mya) are mostly bipeds, more or less chimp size brains. Kenyanthropus Platuops (3.5 mya). One of the major key difference between human and chimpanzees are the duration of child development, baby chimps develop faster than the baby humans.
