Sahelanthropus tchadensis |

may be closest common ancestor to chimps

Australopithecus afarensis |
3.0-3.9 mybp |
375-550 |
3'6"- 5' |
small
canines, jaw intermediate |
low
forehead, flat nose, no chin, brow ridge |
sexually
dimorphic gracile, "Lucy"

|
Australopithecus africanus |
2-3 mybp |
485-625 |
4' |
parabolic jaw reduced canines |
panned, brow ridges present, protruding jaw |
gracile. There is a suggestion that some
material may be as little as
1 my old (!) may
have used sticks and stones as digging tools |
|
Paranthropus robustus |
1.5-2.0 mybp |
530 |
4' |
small
front teeth, large back |
panned no forehead, small sagittal crest |
robust, may have used
bones as digging tools,
some classify as genus Australopithicus See
this too |

Paranthropus
boisei |
1.1-2.1 mybp |
530 |
4' |
larger
than robustus with anterior teeth reduction |
sagittal crest, low forehead, panned face |
robust, some classify as genus Australopithicus. Sexual dimorphism is
reduced. Fed on hard, low-quality foods |
|
Homo
habilis |
1.5-2.4 mybp |
500-800 |
5' |
human-like |
protruding jaws,
large molars, no chin, brow ridge, long low skull |
Broca's area from
brain cast (more
here),
tool
making, may be several species including Homo rudolfensis NOTE:
Some researchers question if habilis is a direct human ancestor. Had
a precision grip.
"Handy man"
did not use fire |

Homo erectus |
1.8 mybp - 300,000 |
750-1225 |
5' |
human-like |
protruding jaws,
large molars, no chin, brow ridge, long low skull |
probably used
fire, efficient
stone tools,
first to leave Africa
and migrated to Asia and Europe. Generally considered to be a
direct human ancestor.

Homo
neanderthalensis |
230,000-30,000 ybp |
1450 |
5'6" |

brute-like (even

Homo floresiensis |
to 18,000 ybp |
360 |
~ 3'3" |
human like with robust lower
jaw |
Small slightly elongated
skull with small brow ridges. Weak chin. |
Probably evolved from H. erectus in Indonesia. Limited habitat and
isolation led to extraordinarily stature. This is NOT a pigmy. |

Homo sapiens |
