Recent research indicates that, in non-human primates, whole brain size is a better measure of cognitive abilities than brain-to-body mass ratio. The total weight of the species is greater than the predicted sample only if the frontal lobe is adjusted for spatial relation. [ 19 ]
The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
Similarly sized brains, such as a cow or chimpanzee, might in that scenario contain very different numbers of neurons, just as a very large cetacean brain might contain fewer neurons than a gorilla brain. Size comparison between the human brain and non-primate brains, larger or smaller, might simply be inadequate and uninformative – and our ...
A meta-analytic review by McDaniel found that the correlation between intelligence and in vivo brain size was larger for females (0.40) than for males (0.25). [18] The same study also found that the correlation between brain size and Intelligence increased with age, with children showing smaller correlations. [18]
After all of the data, all observations concluded that the main development that occurred during evolution was the increase of brain size. [52] However, recent research has called into question the hypothesis of a threefold increase in brain size when comparing Homo sapiens with Australopithecus and chimpanzees. For example, in an article ...
In a sample of 10 P. boisei specimens, brain size varied from 444–545 cc (27.1–33.3 cu in) with an average of 487.5 cc (29.75 cu in). [36] However, the lower-end specimen, Omo L338‐y6, is a juvenile, and many skull specimens have a highly damaged or missing frontal bone which can alter brain volume estimates. [ 37 ]

Aiken et al. (2024) report the earliest cetacean remains in the Black Sea region, and report that the harbour porpoise, the common bottlenose dolphin and the common dolphin were present in the Bosphorus as early as 8000–7800 years ago, and that cetaceans reached the northern and northeastern Black Sea, including the Kerch Strait, by 5500 ...
