NOTICE: a significant percantage of aggression in primates occurs as male-female agonism during feeding competition. Interestingly, both the baboon & the gorilla (both have short fingers & relatively broad palms relative to palm length) are known for high percentages of non-food related aggression behavior. There is only one other primate species which shows the same unusual characteristic for a primate: the baboon! Though the gorilla (just like the tarsier) has large hands relative to it's body proportions, in gorillas the fingers are much shorter than palm breadth. This concerns actually a very unusual characteristic for a primate species, though the same characteristic is also seen in the aye-aye - another 'prosimian'!Ī reversed tendency is seen in the primate species known for having the largest hands of all primates: the gorilla!
#Human vs chimpanzee hand full
However, in the perspective of limb length their hands are relatively large in terms of full body proportions tarsiers probably even have the largest hands of all primates - though this can for a large part be attributed to the relatively long digits which are much longer than the length of the palm!
The tarsier also became known as the smallest of all (known) primates living on planet earth, and their hands size is accordingly the smallest of all in terms of absolute proportions. Interestingly, the hand of the tarsier primate (see top picture) fully confirms that it varies significantly from the typical 'prosimian' hand morphology!īecause 'prosimians' nearly always show the tendency for the 4th digit (ring finger) to develop as the longest digit, while in simians the 3th digit is nearly always the longest digit - see picture on the right! It took untill 1986 before the tarsier (formerly known as a 'prosimian' known as the smallest primate living on earth!) became recognized as a sister group to the 'simians' due to DNA related evidence.Īs a consequence the tarsier became grouped together with the 'simians' (including humans) as the infraorder 'Haplorrhini' and the non-tarsier prosimians became grouped as the infraorder 'Strepsirrhini' (which includes: lorises, bush babies, pottos & lemurs). PRIMATE RING FINGER CONFIRMS THE NEW PRIMATE CLASSIFICATION!ĭuring the 20th century the classic primate classification seperating 'prosimians' vs. However, Old World & New World monkeys appear to have better survival skills than most human apes (only human kind is outperforming the monkeys).Īnd in the earlier primate classification - which became outdated since 1986 - the so-called 'prosimians' (= lower primates) tend to live more closer to the equator than the so-called 'simians' (= higher primates, including: New World monkeys, Old World monkeys, apes and humans). Human kind found it's way to survive at (cold) locations far away from the equator but other 'human apes' (such as the chimpanzee, bonobo, gorilla & orangutan) are only able to survive in the wild in tropical or subtropical forest near the equator. The various primate groups have spread around the world.Īll primate species show a tendency to live at locations near the equator (see picture on the right). In order to understand the typical characteristics of the human hand better, it is also interesting to take a closer look at how However, there are several differences which set the human hand apart from the primate hand.Īnd each primate group also has various typical characteristics!
