In succeeding years many further specimens have been found, not only in the German Neander Valley, but in with rickets, caused by a deficiency of vitamin D.He considered that the flattened head was caused by repeated powerful blows (his examination was done pre Darwinism 1859).Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant.Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.When more finds came to light with what also appeared to be rickets, it was considered far too much of a coincidence and for lack of any other explanation they became relegated to a sub-human category.The French palaeontologist Marcellin Boule, concluded walked stooped forward which fitted in with the then new current thinking of Darwins evolutionary theory of the origin of man (these new assumptions were made post Darwinism 1859).This assumption is backed by numerous scientific studies and is relatively sound.However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.

near Dusseldorf, Germany uncovered a skull and bones.

Naturally occurring graphite occurs in two forms, alpha and beta.

These two forms have identical physical properties but different crystal structures.

While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.

Thus radioactive dating relies purely on assumptions.

This black soot, also known as lampblack, gas black, channel black or carbon black, is used to make inks, paints and rubber products.
