A child's current height and bone age can be used to predict adult height. [4] Other uses of bone age measurements include assisting in the diagnosis of medical conditions affecting children, such as constitutional growth delay, precocious puberty, thyroid dysfunction, growth hormone deficiency, and other causes of abnormally short or tall stature.
Not all bones grow at the same rate and the individual growth rate of a bone changes over a lifetime, [1] therefore periodic growth marks can take irregular patterns. This indicates significant chronological events in an individual's life. The use of bone as a biomaterial is useful in investigating structure-property relationships. [3]
In 1888 Rollet measured the stature and the lengths of the long bones of 50 male and 50 female French cadavers ranging in age from 24 to 99 years, and presented tables for stature estimation. He determined the average length of the long bones of those who presented the same stature. [6]
This unit of measurement is credited [2] to the Greek sculptor Polykleitos (fifth century BCE) and has long been used by artists to establish the proportions of the human figure. Ancient Egyptian art used a canon of proportion based on the "fist", measured across the knuckles, with 18 fists from the ground to the hairline on the forehead. [3]
DNA recovered from bones discovered in 8-meter-deep cave dirt is shaking up what we know about some of the earliest modern humans.
Allometry (Ancient Greek ἄλλος állos "other", μέτρον métron "measurement") is the study of the relationship of body size to shape, [1] anatomy, physiology and behaviour, [2] first outlined by Otto Snell in 1892, [3] by D'Arcy Thompson in 1917 in On Growth and Form [4] and by Julian Huxley in 1932.

The bones were determined to be up to 47,500 years old. Until now, the oldest Homo sapiens remains from northern central and northwestern Europe were about 40,000 years old.
A photo-realistic human face has been reconstructed based on information gleaned from 3,700-year-old bones, notes smithsonian.com.. According to the BBC, the remains were found in a grave in the ...
