To support these claims, Gould presented the case of Samuel George Morton, a 19th - century American physician and scientist famous for his measurements of human skulls, particularly their cranial capacity (the skeletal equivalent of brain size).

Gould reanalysed Morton's data, and famously argued in Science and in his prize - winning bestseller The Mismeasure of Man, that Morton had manipulated his samples, made analytical errors, and mismeasured cranial capacities as a consequence of a racist bias.

This was a presentation given by Tom Schoenemann of the University of Michigan at Dearborn, and what he did was to survey cranial capacity and body weight data, so brain size and body weight data for a bunch of modern humans and also [a] fossil one, and he plotted all of this on a graph and he determined that the brain size of the Flores hominid relative to her body size more closely approximates that what you see in the Australopithecines, which are much older, you know.

The probability of occurrence of a 700cc cranial capacity in a modern person must be rather tiny, given that mean capacity for the species as a whole is about 1450cc.

It's cranial capacity was the smallest ever recorded in an adult early human, and at 410 cc it was not much larger than that of a modern chimpanzee.

Morton took detailed measurements of these skulls with a particular focus on cranial capacity, the skeletal equivalent of brain size [8]--[10].

Morton did not consider the influence of sex or stature on cranial capacity, but it would have been impossible for him to use those parameters to bias the averages he reported (see Box 3).

The changes in average cranial capacity from Morton's seed - based measurements to shot - based measurements can not be reconstructed with any certainty, incorporate erroneous seed measurements made by Morton's assistant, yielded a broad range of changes (− 10 to +12 in3) hidden by Gould's mean, and are confounded by the shifts in sample composition (circa 50 %) between the two rounds of measurement.

As most of the adult cranial capacity is reached by age 10 or 11, it is likely that the adult ECV of WT 15000 would be no more than about 1000 - 1050cc, which is still well within the modern human range of about 800 - 2000cc.19 On the same page Jue points out that a brain capacity of 1400cc applies to the Vertesszöllos erectus specimen which is dated at around 350kya (kiloyears ago = thousands of years).

In particular, cranial capacity variation in human populations appears to be largely a function of climate, so, for example, the full range of average capacities is seen in Native American groups, as they historically occupied the full range of latitudes [18].

(*) Note: for convenience, I use the term «brain size» instead of «cranial capacity».

Tobias (1970) says that according to Dart, «apparently normal human beings have existed with brain - sizes in the 700's and 800's» (maybe Molnar's claim is a mis - statement of this), and that the smallest cranial capacity ever documented is 790 cc.
