Question:

Skeletal discussion anatomy homework help please?

a portion of an ancient skeleton haas been uncovered in asia. since the skull is missing, the discoveres can not determine whether the skeleton is from a human or some type of ape. the only portions that the excavators have been able to find are the pelvis and one complete leg. what should they look for?this is not true lol, just a skeletal discussion question in anatomy.

Answer:

Skeletal system..the blood formation refers to the function of the bone marrow..the others are pretty self-explanatory.
Its kind of unclear what the question even is. Are you supposed to describe how you would determine whether the skeleton is a modern human based on the post-cranial skeleton only? Next time be more clear. 1) A human *is* an type of ape. Take a close look at human taxonomy. We're part of the superfamily Hominoidea - the apes. 2) If you need to determine whether the skeleton is from a H. sapiens, then you can look at the shape of the pelvis, and the relative length of the limbs. How long are the arms in relation to the legs? If the skeleton belongs to a modern human, the arms should be relatively short in relation to the legs. In terms of the pelvis, what is the shape or the pelvic girdle? It is short and broad, or long and thin? Does it appear to be well-shaped to cradle the visceral contents of the body? If it does, and if it is shorter and broader, instead of larger, long, and narrow, it is a biped. Check out the feet. Is the big toe divergent? If not, it's a biped. Check out the hands. Are the phalanges long and curved? Or shorter and a bit stout? Long, curved phalanges indicate non-human. Notice I haven't given you very much technical anatomical terminology. Just some hints so you can work out the rest for yourself.
