Partly due to Melville, the Sperm whale is commonly associated with the mythological Leviathan of Biblical lore. The sperm whale is the largest toothed whale, with adult males measuring up to 20.7 metres (68 ft) long and weighing up to 80 tonnes (79 long tons; 88 short tons). Areas such as the frontal lobe, temporal lobe, parietal lobe and visual/auditory systems among others may be measured separately to determine an animals level of performance related to that specif brain function. Sperm whales are easily recognized by their massive heads and prominent rounded foreheads. Sperm whales are prodigious feeders and eat around 3% of their body weight per day. The difference in this between our species is so extreme that it is still quite possible that their cerebral cortex might be more densely packed and ‘hungrier’ than ours. google_color_border = "FFFFFF"; The females take care of their offspring in communities; staying close to them in tropical waters. Most of what we know about cetacean intelligence has been gathered from research done on dolphins. In addition, long-line fishing operations in the Gulf of Alaska have complained that numerous Sperm whales have taken advantage of their fishing operations to eat desirable species straight off the line, sparing the whales the need to hunt them themselves. However, carbon dates in the relevant range are susceptible to distortion by the intrusion of traces of new carbon into old deposits. However, white scars on the bodies of Sperm whales are believed tvo be caused by squid. The blob: In July 2003 a huge blob of white flesh was found washed up on a beach on the coast of southern Chile. Data on the sophistication of tool manufacture, and use of body decoration has been used for a long time, but, until recently, it contained a flaw. Bushy blows: The blowhole is situated very close to the front of the head and shifted to the whale's left. Because dolphins and whales (such as the sperm whale) possess many of the same abilities and cognitive skills it is likely that many of these same mental strengths also exist among the sperm whale species. This damage may indicate that Sperm whales are susceptible to decompression sickness, and sudden surfacing could be lethal to them. All rights reserved. I believe that the current balance of evidence leans in favour of neanderthals superiority, and we can expect more definitive findings soon. This species of whales has the ability to emit vocalizations and clicks, also called echolocation. Their brain endocasts seem to be about three standard deviations larger than those of modern humans. Ambergris was (and remains) a very valuable substance once used in perfumes. Scientists have yet to understand its function, but believe it may help the animal regulate its buoyancy. Another very peculiar characteristic of sperm whales, is their small dorsal fin located near the caudal fin; preceded by a series of knuckles along the spine. The case is the largest organ in the head of the sperm whale. These sounds are employed to locate themselves when navigating and to communicate with each other. Even in the absence of any understanding of how neanderthal or modern human genes work we could still gather evidence, by looking at variation within any one ethnic group of modern humans, as long as the individuals within the sample have known proportions of neanderthal DNA. They are easily identified because they have a huge square head,  with a rounded and very prominent forehead. The animals were targeted for oil and ambergris, a substance that forms around squid beaks in a whale's stomach. google_ad_channel =""; The left hemisphere, whose surface had been damaged during removal, was preserved whole in formalin. Unfortunately, our current neanderthal genome data is not of sufficient quality to differentiate the two, but assuming they have the same ratio of the two to modern humans, then we may expect they have a +25 IQ point advantage. The reason this research was considered compelling at first is that there was a belief that animals that lived in areas where more intelligence is required for survival would grow larger brains to deal with the additional cognitive needs of living in such an area, however this idea as well as others have since come under scrutiny as more compelling arguments and tests have been conducted. Below the case in the head is a tissue-filled chamber that also contains high grade spermaceti oil. In order to better understand the brain and how it functions tests are now often performed using MRI scans during specific activities in order to measure the brains response to certain impulses. The sperm whale (physeter macrocephalus) is a large toothed whale that is part of the cetacean species, which includes all species of whale, dolphin and porpoise. (adsbygoogle = window.adsbygoogle || []).push({}); There are huge creatures that live in our oceans, which are called Sperm Whales,  and have very special characteristics.

Neanderthals have 350 copies of it, whereas we average only 278. Not all new behavioural evidence is in favour of the intellectual parity of the two species. Note: This article is created to show the arguments among the various theories and ideas related to intelligence and brain size and therefore is not created to be I biased opinion or argument of one side or the other.

They also tend to change groups frequently. In the better studied populations of Europeans and East Asians the neanderthal proportion can vary in any one individual from 0%, to an unlikely theoretical maximum of circa 20% (see At least 20% of Neanderthal DNA is in Humans).
