Chimpanzee have low slope frontal bone as compared to humans. In chimpanzee chin mouth is behind and in humans it is ahead. Lastly, in chimpanzee's sagital crest is present and it is absent in humans.
What are the structural structure between humans and chimpanzees ?Humans have a broad, flatter-fronted chest, which helps us stand more erect by shifting the center of gravity back toward the spine. The rib cage of an ape is more rounded and barrel-shaped. The S-shaped shape of the human spine elevates the head and torso above the center of gravity.
Chimpanzee's arms are longer than its legs, it can swing and climb with much greater ease. The shorter legs are better suited for standing, running, and walking. The pelvis is more suited for sitting since it lacks a tail.

The property (quality) of fossils allows scientists to determine the relative ages of rock layers are fossils show change over time as species evolve.
What is the minimum age of a fossil?A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch. Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.Chemistry is present in this process, more precisely the element Carbon. The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).The term fossil can be defined as the remains or the retained remnants of ancient species, or signs of their remains. Fossils are not the remnants of living organisms.They are stones. A fossil can save a whole organism or only a portion of one. Fossils can be formed from bones, shells, feathers, or leaves.
