Human Evolution

5 million years ago to present

Now, Flores man makes it seem that yet another type of
human was around for at least 17,000 more years.
Archaeologists and anthropologists and many other
scientists will study the Flores fossils. It may be years before
they agree on where H. floresiensis should be placed on the
human “family tree.”

Questions:

1. How do archaeologists know that Flores man was a
   hunter?


2. Why might their home on an island have made Flores man
   small?


3. Why was the discovery of Flores man important? What
   effect did the discovery have on scientific understanding of
   human history?


4. How are modern humans and Neanderthals related?
