This was also near Piltdown village in East Sussex, England. There was also a set of teeth and a jawbone. The scientific significance would be that it would of taught us the connections between humans and apes. This was something scientist payed so much attention to because they though they have found a new species of the life of a human/ape.

As the years went by, we had advance technology to take a closer look at the ancient artifacts.

1.For your homologus traits provide the following information: a. Briefly describe (NOT just identify) the two different species that possess the homologus trait.  Homologies are shared between two different species. Humans and dog are two homologous, two different species but have traits that makes them similar to each other.  b. Describe the homologus trait of each species, focusing on the differences in structure and function of the trait. Why do these homologus traits exhibit differences between the two species? Make sure your explanation is clear and complete.  If we look at the image of a human hand a dog’s paw, we can see that they share a similar bone structure in the hand. However on the dog, the thumb is smaller compared to a human thumb, which is larger in size. Making the thumb of the dog a vestigial area. We see this difference because over time human’s learned how to use the function of the thumb in everyday life. Including grabbing or gr...
