This document summarizes key hominin species in human evolution including Homo rudolfensis, Homo habilis, Homo erectus, Homo sapiens, and Cro-Magnons. It discusses where and when these species lived, debates about relationships between Homo rudolfensis and Homo habilis, and physical adaptations of Homo erectus. The document emphasizes that Homo sapiens evolved in Africa around 200,000 years ago and have since spread worldwide, noting that understanding evolution enhances appreciation for life rather than demeaning humanity.

3.  Oldest potential ancestor
of hominin species

9. Homo Rudolfensis
Homo Habilis

10. Nickname: Handy Man
Where Lived: Eastern and Southern
Africa
When Lived: 2.4 million to 1.4 million
years ago
Where Lived: Eastern Africa (northern
Kenya, possibly northern Tanzania and
Malawi)
When Lived: About 1.9 million to 1.8
million years ago
When Lived: About 1.9 million to 1.8 million years ago

11. 1. Was Homo rudolfensis/homo habilis on the
evolutionary lineage that evolved into
later species of Homo and even perhaps our
species, Homo sapiens?
2. Are Homo rudolfensis and Homo
habilis indeed different species, or are they part
of a single, variable species? Or was one the
ancestor of the other?

13. Where Lived: Northern, Eastern, and Southern
Africa; Western Asia (Dmanisi, Republic of
Georgia); East Asia (China and Indonesia)
When Lived: Between about 1.89 million and
143,000 years ago
Early African Homo erectus fossils are the oldest known early
humans to have possessed modern human-like body
proportions. These features are considered adaptations to a
life lived on the ground, indicating the loss of earlier tree-
climbing adaptations, with the ability to walk and possibly run
long distances.

16. Cro-Mangnons

18. Where Lived: Evolved in Africa, now worldwide
When Lived: About 200,000 years ago to present
“The species that you and all other living
human beings on this planet belong to is
Homo sapiens. During a time of dramatic
climate change 200,000 years ago, Homo
sapiens evolved in Africa. Like other early
humans, they gathered and hunted food,
and evolved behaviors that helped them
respond to the challenges of survival. “

21. “Evolution isn't just a story about where we came
from. It's an epic at the center of life itself. Far from
robbing our lives of meaning, it instills an appreciation
for the beautiful, enduring, and ultimately triumphant
fabric of life that covers our planet. Understanding
that doesn't demean human life - it
enhances it. “
-Kenneth R. Miller
