A human is any member of the species Homo sapiens, meaning "wise man." Development of the informatics and data archiving tools needed to provide permanent storage for the wide array of information collected by the activities listed above, and to facilitate continued access to this information. What are the general characters of pteridophytes? How did life evolve on Earth? Homo Rhodesiensis, and the Gawis Cranium: H. rhodesiensis, estimated to be 300,000-125,000 years old, most current experts believe Rhodesian Man to be within the group of Homo heidelbergensis though other designations such as Archaic Homo sapiens and Homo sapiens rhodesiensis have also been proposed.

Suggested Citation:"5 Conclusions and Recommendations. This migration and origin theory is usually referred to as the single- origin theory.

1. In the context of man, the biological evolution started with the ‘Origin of life’. Understanding Climate's Change on Human Evolution explores the opportunities of using scientific research to improve our understanding of how climate may have helped shape our species. All rights reserved. Precisely when early humans started to use tools is difficult to determine, because the more primitive these tools are (for example, sharp-edged stones) the more difficult it is to decide whether they are natural objects or human artifacts. Kenyanthropus (3-2.7 mya), with species Kenyanthropus platyops. To what extent Scientists can often use the same “evidence” to support contrasting hypotheses depending on which evidence (fossils or molecular clock/ DNA studies) one gives more weight to.
