There are 206 bones in the skeletal system.
This is known as Pancytopenia.
The three hematopoietic cell lines lead to the formation of red blood cells, white blood cells and platelets. All these cells play important roles in various body functions.
Pancytopenia is a condition in which the quantity of red blood cells, white blood cells and platelets decrease in the body of a person. Chemotherapy and radiation are serious procedures that along with killing the cancerous cells also destroy many of the normal cells of the body. Hence, chemotherapy and radiation leads to decrease in all the three hematopoietic cell lines of the body causing a condition referred to as Pancytopenia.

Answer:
Fossils provide direct evidence of evolution. They show the changes of animals from ancient organisms to present form. Fossils are the preserved remains of earth layers. There are 4 types of fossils-
Original fossils that are not very old. e.g. teeth, skeleton, shells.
Frozen fossils
less permanent fossils
casts, molds, and prints - wings, skin, leaves, etc.
The fossils show the adaptive radiation in horses, humans. The transition fossils form the connecting link between different groups such as fish and amphibians, reptiles and birds, etc.
e.g. Archeopteryx is the connecting link between the reptiles and birds.
The modern horse Equus have several ancestor species, we came to know from the fossil records.
The fossil record shows the evolution of humans and their ancestors.
