Dawson later dug up another bone, this time a jawbone that was part of the same skull. In December of 1912, Woodward made the first public announcement on what could be the connection between humans and apes. It was dubbed as the Piltdown man. Soon, more fossils were discovered in Asia and Africa. These fossils were younger than the Piltdown man yet less human. After World War II, new technology arose, and the Piltdown man was tested. The results showed the fossils were young. Scientists begun questioning and became skeptical of the Piltdown man. Then in 1953, the first full-scale analysis with better dating methods proved the staining on Piltdown man’s bones were superficial and the teeth had been filed down. It was also discovered that the jawbone dated back less than 100 years an...

1.      Homologous Traits a.      Humans are bipedal mammals in the family Hominidae with origins in Africa about 250,000 years ago.. Giraffes have long necks, have distinct spotted markings and are the tallest mammals on Earth. b.      Despite the size differences, both giraffes and humans have seven neck bones. Giraffes use their necks to reach for leaves in tall trees. Each neck bone is about 11 inches. Humans have a much smaller neck bones. Humans do not use their neck for neck battles like giraffes do. c.      The common ancestor of these two species is a mammal from the dinosaur era. The skeleton of the prehistoric mammal was reconstructed and was discovered that it had 7 neck bones in its vertebrae. 2.      Analogous Traits a.      Ducks are birds who like and live in places like ponds, streams and rivers. They a...
