Evolution is change over a long period of time. An organism’s characteristics change over time due to its DNA. The DNA determines how an organism looks. The process of evolution is over millions of years. Scientists use fossils‚ embryology‚ comparative anatomy‚ and the biochemistry to get data fro the organisms of their evolutionary histories. For this purpose for doing this lab is to related organisms’ skull evolved or change over time. Fossils are past living remain organism that left behind and

Introduction I have always wanted to travel the world and discover many new artifacts and fossils that have not been found before. I found myself very interested and passionate about evolution and how our ancestors evolved into modern human. That is when I decided to pursue a career in paleoanthropology because I knew that was a career with many opportunities to travel the world and possibly discover fossils. In college‚ I have had a lot of hands on field experience in paleontology and it was a place

Introduction to Hominid Evolution Hominid evolution is the theory of the origins of the human species (Homo sapiens). Current understanding of human origins is obtained largely from the findings of paleontology‚ anthropology‚ and genetics. Of all primates‚ humans share particularly close affinity to other members of a group known as hominoids‚ or apes. Humans and their immediate ancestors‚ known as hominids‚ are notable among hominoids for their bipedal locomotion (Using two legs for walking)

Climate Effects on Human Evolution This article explores the hypothesis that key human adaptations evolved in response to environmental instability. This idea was developed during research conducted by the Smithsonian’s Human Origins Program. Natural selection was not always a matter of ‘survival of the fittest’ but also survival of those most adaptable to changing surroundings. (Illustrations for this article coming soon.)

of the last common ancestor of humans and living apes. The time split between humans and living apes used to be thought of fifteen to twenty millions of years ago‚ but now the time period has shifted to around five million years ago. Ardipithecus ramidus is said to have live around 4.4 million years ago. The original fossils from this species were placed with the Australopithecus genus; however‚ a new genus was designated to this group by Tim White. Tim White is an anthropologist and co-author

and around 14 million years ago‚ the Ponginae (orangutans)‚ diverged from the Hominidae family.[3] Bipedalism is the basic adaption of the Hominin line‚ and the earliest bipedal Hominin is considered to be either Sahelanthropus or Orrorin‚ with Ardipithecus‚ a full bipedal‚ coming somewhat later. The gorilla and chimpanzee diverged around the same time‚ about 4-6 million years ago‚ and either Sahelanthropus or Orrorin may be our last shared ancestor with them. The early bipedals eventually evolved

The many species of australopithecus include A.(australopithecus) ramidus‚ A. anamenesis‚ A. afarensis‚ A. africanus‚ A . acthiopicus‚ A. robustus‚ and A. boisei. The oldest known and identified species of australopithecus that roamed the earth was a. ramidus who lived about 4.5 million years ago. Next came A.
