When did anatomically modern humans appear in the fossil record?
200,000 years ago
Anatomical modernity. Bones of primitive Homo sapiens first appear 300,000 years ago in Africa, with brains as large or larger than ours. They’re followed by anatomically modern Homo sapiens at least 200,000 years ago, and brain shape became essentially modern by at least 100,000 years ago.
What is true about the fossils of the earliest known anatomically modern humans?

Where did anatomically modern humans evolve from?
Africa
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means ‘upright man’ in Latin.
What is the fossil record of humans?
The fossil record of human ancestors may go back 6 million years or more, and the genus Homo arose at least 1.8 million years ago when australopithecines evolved into human ancestors known as Homo habilis.
What traits characterize anatomically modern humans?
Anatomically, modern humans can generally be characterized by the lighter build of their skeletons compared to earlier humans. Modern humans have very large brains, which vary in size from population to population and between males and females, but the average size is approximately 1300 cubic centimeters.
Who are the first known anatomically modern humans in Africa?
The oldest known evidence for anatomically modern humans are fossils found at Jebel Irhoud, Morocco, which date back some 360,000 years ago. However, there is some debate whether they belong to Homo sapiens or a closely related species.
Where did Neanderthals come from?
Neanderthals evolved in Europe and Asia while modern humans – our species, Homo sapiens – were evolving in Africa. Judging from fossil evidence from Sima de los Huesos in northern Spain and Swanscombe in Kent, the Neanderthal lineage was already well-established in Europe by 400,000 years ago.
Are there fossils of modern humans?
From skeletons to teeth, early human fossils have been found of more than 6,000 individuals. With the rapid pace of new discoveries every year, this impressive sample means that even though some early human species are only represented by one or a few fossils, others are represented by thousands of fossils.
What do traits of anatomically modern humans include quizlet?

What was not commonplace in the archaeological record before modern humans?

What are some examples of transitional fossils in humans?
Examples of this in humans are the skeletal changes in the pelvis and the foot to allow for walking upright. We do not share these with any other primates. Transitional fossils in the human fossil record are distinguished at both the genus and species level.
