This new species had a larger brains better fit for survival‚ they created more sophisticated tools for hunting and created fire. They also created a functional language for them to communicate. While the new species gained intelligence about their world they evolved into the species we have today known as Homo Sapiens. The frontal cortex of the brain grew allowing more room for conscious thinking

REASONING AND INTERPRETATION – Practice questions 1. Understanding the ecological mechanism that causes extinction is fundamental to conservation as not all organisms are threatened by the same factors. A total of 1012 threatened bird species in 95 families were studied to see how they were threatened by different factors: · habitat loss · persecution by humans and introduced predators · other factors (introduced competitors‚ hybridization and disease) and unknown risk factors.

According to findings of “expressions of a modern mind”‚ when do scientists believe that modern humans – Homo sapiens – first appear? Scientists argue that the earliest species may have existed 200‚000 years ago. 9. What advantages‚ if any‚ do modern humans appear to have over Homo erectus and

What makes these theories the most highly debateable in paleoanthropology is that 30‚000 years ago‚ the taxonomic diversity previously seen amongst homo sapiens‚ homo erectus and homo Neanderthals had vanished and humans everywhere had evolved into the anatomically and behaviourally modern form; there is much deliberation as to how this occurred which rose this differing schools of thought; one that emphasises multiregional

Because they are believed to have evolved apart from Homo hominids‚ it is not important to cover these species in detail. Homo erectus lived between 300‚000 and 1‚800‚000 years ago‚ and still had portruding jaws and a "keel" effect on the top of the cranium. It‚ like its predecessors‚ had no definable chin‚ and thick brow ridges. However‚ skull

Evolution of human intelligence The evolution of human intelligence refers to a set of theories that attempt to explain how human intelligence has evolved. These theories are closely tied to the evolution of the human brain and to the emergence of human language. The timeline of human evolution spans approximately 7 million years‚[citation needed] from the separation of the Pan genus until the emergence of behavioral modernity by 50‚000 years ago. The first 3 million years of this timeline
