Are lemurs prosimians?
Primates can be broken into two suborders: anthropoids and prosimians. Monkeys, apes and humans are anthropoids. Lemurs are prosimians. Other prosimians include galgoes (bushbabies) found in Africa, lorises found in Asia, and tarsiers found in Borneo and the Philippines.
What makes a lemur a prosimian?
Prosimians are a group of primates that includes all living and extinct strepsirrhines (lemurs, lorisoids, and adapiforms), as well as the haplorhine tarsiers and their extinct relatives, the omomyiforms, i.e. all primates excluding the simians.
Which of the following animals are prosimians?
The prosimians include present-day lemurs, lorises, and galagos.
How are they different from prosimians like the lemurs?
The second toe of the hind foot of prosimians has a long claw which they use for grooming. The other toes, on both the hands and the feet, have flattened nails instead of curved claws. Lemurs, which walk along branches on all fours, have longer hind legs than front ones.
What evolved into prosimians?
Prosimians (meaning before apes) were the first group of primates that diverged from a common mammalian ancestor. This group includes lemurs, lorises and tarsiers.

When did prosimians first appear?
50-55 million years ago
The earliest ones are found in the fossil record dating to 50-55 million years ago. These first prosimians thrived during the Eocene Epoch. There were no monkeys or apes for them to compete with yet.

Most prosimians are not aggressive toward humans, but caregivers might find it startling when an aye-aye jumps toward them or even clings to them.
