C  Leather working instruments that showed Neanderthals were manipulating animals pelts in order to making clothing and shoes

D  A Levallois tool making technique that allowed Neanderthals to control the size and shape of their stone tools

A  Neanderthals had short and stocky bodies that allowed them to reduce heat in a sub-tropical environment

B  Neanderthals had bodies of equal size to Homo sapiens, which allowed them to effectively compete for resources in a mild climate

C  Neanderthals had bodies that were lighter and leaner than Homo sapiens, which allowed them to retain more heat in an arctic environment

A  The Dmanisi were found to be advanced hunters, which negated the theory that Homo erectus migrated because they were following animals they scavenged from.

B  The Dmanisi were very small in stature and lacked the features we originally believed Homo erectus needed in order to travel long distances outside of Africa.

C  The Dmanisi were found in Georgia outside of Africa and date back to 1.8 mya, which pushes the date of migration by Homo erectus back nearly 1 million years.
