The sperm whale’s head comprises 25 to 35 percent of its entire body length.
The mature adult sperm whale’s brain weighs an average of 18 pounds, and can grow to be nearly 500 cubic inches in size..
What race has the smallest brain?
The Etruscan shrew is the smallest terrestrial mammal and, with a weight of only 64 mg, has one of the smallest brains of all mammals.
Are bigger brains better?
Summary: Using a large dataset and controlling for a variety of factors, including sex, age, height, socioeconomic status, and genetic ancestry, scientists found that people with larger brains rated higher on measures of intelligence and educational attainment.

What is the 2nd smartest animal?
DolphinsDolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
Which animal is more intelligent than humans?
chimpanzeesTake chimpanzees, which share 99% of their DNA with humans.
Does brain size affect intelligence?
In healthy volunteers, total brain volume weakly correlates with intelligence, with a correlation value between 0.3 and 0.4 out of a possible 1.0. In other words, brain size accounts for between 9 and 16 percent of the overall variability in general intelligence.
What animals have bigger brains than humans?
Bottlenose dolphins have bigger brains than humans (1600 grams versus 1300 grams), and they have a brain-to-body-weight ratio greater than great apes do (but lower than humans). “They are the second most encephalized beings on the planet,” says Marino.
Are dolphins smarter than humans?
Are dolphins smarter than humans? Current tests for intelligence indicate that dolphins do not possess the same cognitive abilities as humans and are thus not the “smarter” species. Like humans, dolphins possess the ability to beneficially alter their surroundings, solve problems, and form complex social groups.
Can a brain be smooth?
Lissencephaly, which literally means “smooth brain,” is a rare, gene-linked brain malformation characterized by the absence of normal convolutions (folds) in the cerebral cortex and an abnormally small head (microcephaly). In the usual condition of lissencephaly, children usually have a normal sized head at birth.
Which human has the biggest brain in the world?

Are killer whales smarter than humans?
By that measure, human brains, by comparison, are seven times average. Orcas’ brains are 2 1/2 times average — similar to those of chimpanzees. … In other words, orcas might be even much smarter than the size of their big brain suggests.
Are human brains getting smaller?
Some of the shrinkage is very likely related to the decline in humans’ average body size during the past 10,000 years. Brain size is scaled to body size because a larger body requires a larger nervous system to service it. As bodies became smaller, so did brains.
Who use maximum brain in the world?
The 10 percent of the brain myth is a widely perpetuated myth that most or all humans only use 10 percent (or some other small percentage) of their brains. It has been misattributed to many celebrated people, notably Albert Einstein.
What is the largest brain ever recorded?
The heaviest human brain ever recorded weighed 5 lb., 1.1 oz or about 2.3 kg (statistic from The Guinness Book of World Records, 1997).
What increases brain size?
Brain health decreases with age, with the average brain shrinking by approximately five per cent per decade after the age of 40. Studies in mice and rats have consistently shown that physical exercise increases the size of the hippocampus but until now evidence in humans has been inconsistent.
Who stole Albert Einstein brain?
Thomas HarveyAlbert Einstein, the Nobel prize-winning physicist who gave the world the theory of relativity, E = mc2, and the law of the photoelectric effect, obviously had a special brain. So special that when he died in Princeton Hospital, on April 18, 1955, the pathologist on call, Thomas Harvey, stole it.

When did humans get smart?
The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language. The timeline of human evolution spans approximately 9 million years, from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago.
