Arboreal Hypothesis

Primate traits such as grasping hands and binocular vision were adapted to life in the trees.

Tertiary

65-2 million years ago

Paleocene

Proto-primate,

65-55 million years ago

Ecocene

Prosimian-like Primates

55-34 million years ago

Oligocene

First Anthropoids

34-23 million years ago

Miocene

Hominoids widespread

23-5 million years ago

Pliocene

Hominids

5-2 million years ago

Paleocene "Primates"

65-55 Million years ago

Plesiadapiform

Found in North America, Europe, Asia, and possibly Africa

Possibly a separate order, but still potentially related.

Eocene Primates

55-34 million years ago

Euprimates: the first true primates

Ancestral to modern prosimians

Adapids-related to modern lemurs

Omomyids--related to modern tarsiers

Oligocene Primates

Period of global cooling and plant and animal extinction

Anthropoids-Monkeys appear, some promisians survive

Anthropoids

Monkeys

Fayum, Egypt

Where primate fossils from the Oligocene period are found

Oligopithicids

Earliest Anthropoids

35 million years ago

Oligocene Primates branch into two families

Propliothecids- ancestors of catarrhines. (Old world monkeys. Asia and Africa, evolved in Situ.

Parapithecids- ancestors of platyrrhinnes. (New world monkeys. Central and South America. Migrated from Africa to South American by 26 million years ago.

Propliothecids

Ancestors of catarrhines. (Old world monkeys. Asia and Africa, evolved in Situ.

Parapithecids

Ancestors of platyrrhinnes. (New world monkeys. Central and South America. Migrated from Africa to South American by 26 million years ago.

Aegyptopithicus

Earliest catarrhine

Fayum, Egypt

Last common ancestor of old world monkeys, apes, and humans

Miocene Primates

23-5 million years ago

Apes spread widely

Proconsul

African Apes

15+ species

Most successful group of early to mid Miocene

Teeth and skulls like apes, bodies like monkeys with tails.

Miocene Apes in Asia

Sivapithicus

Khoratopithicus

Miocene Apes in Europe

Dryopithicus

Oreopithicus

Evolutionary dead ends

Sivapithicus

Late Miocene: 12-8 million years ago

Northern India and Pakistan

Ancestral to Khoratpithicus: 9-6 million years ago in Thailand, direct ancestors to orangutans

Khoratpithicus

9-6 million years ago in Thailand

Direct ancestors to orangutans

Giganthopithicus

Largest primate ever

5 million years ago to 400,000 years ago

May have coexisted with homo erectus

Origin of Modern African Apes

Sketchy fossils records between 13-5 million years ago

Late Miocene fossil records of apes and humans have no been identified

Genetic data plugs some gaps
