The vanity of humans is that we are so intelligent that it puts us apart from all other life.
I reckon that is simply wrong.
We probably haven’t been the most intelligent species on the planet in the past and we probably aren’t now.
If there is a correlation between brain size then we are not the most intelligent species of Homo. Homo neanderthal had bigger brain capacity than us.
Homo neanderthal brain size was larger than the average modern human brain. It averaged 1500 cubic centimetres and an average 3.3 lbs while Homo sapiens has a brain volume of just 1273.6 cm3 for men,
Does that mean they were more intelligent? We’ll never know. We do know that they were the first to produce artwork and created abstract work that seemed to have some shamanic meaning.
In terms of other animals on the planet our brains are a lot smaller than a number of other species. A human brain weighs on average 3.3 lbs. The largest brains are those of sperm whales, weighing about 8 kg (18 lb) – nearly 6 times larger than us!! And then killer whales, weighing about 12–15 lb (5.4–6.8 kg) – 4 to 5 times as big!! An elephant‘s brain weighs just over 5 kg (11 lb) and a bottlenose dolphin‘s 1.5 to 1.7 kg (3.3 to 3.7 lb). We are by no means the animals with the biggest brains.
Perhaps they are all more intelligent than us? We judge them by the fact that they do not produce any technology, read, write or speak. But maybe all that is just our anthropomorphic thinking. Who know what intricate thoughts they have?
Many other creature from Apes to crows display intelligence.
Perhaps we should not think of ourselves as being so special?
