Neanderthals evolve


Neanderthals evolve

Neanderthals lived about 200,000 to 28,000 years ago in Europe and southwestern to central Asia. They are the closest relative to modern humans because of their behaviors and physical attributes.  The first Neanderthal discovery was made in Germany in 1829.

This hominid species had a very distinct look, never before documented. Neanderthals had many of the same physical characteristics as the modern day human. The average male Neanderthal was about 5’5 feet tall and weighed about 143 pounds. Females, on average, were approximately 5’1 feet tall, around 119 pounds. They had a very bulky build, which made it possible for them to conserve body heat; this is part of why they were able to survive the harsh conditions of the ice age. The first Neanderthals did not normally live past the age of 14. Most Neanderthals had a lot of the same physical characteristics including very thick and strong bones, low foreheads, distinct brow bones, and large noses.

Neanderthals had many behaviors that were linked to modern humans. They lived in small groups and never stayed in one place for very long. Their most prominent tool were their strong teeth. However, they also created useful tools that were made from stone or wood; these items helped them to perform every day tasks. Neanderthals were also the first creatures to effectively create and use fire; this new skill benefited them greatly. In addition to this, they were one of the first creatures to walk on two legs and have opposable thumbs.
