Blog 7: Summary

Evolution is a constant process but sometimes it can be difficult for us to consider the ways in which humans are continuing to evolve.  That being said, there are a multitude of observable ways in which humans are evolving biologically, behaviorally, environmentally and culturally.

Human society has evolved in incredible ways even in the last 10000 years.  Although 10000 years may seem like a very long time ago, it is actually just a small fraction of the time hominins have inhabited the Earth.  10000 years ago, the majority of anatomically modern humans or Homo sapiens lived in small groups and subsisted on hunting and gathering.  Over time, as humans developed agriculture and domestication, they began to settle in larger and larger settlements and develop a sedentary lifestyle.  Now in the twenty first century, human society has almost completely evolved from the hunter gatherer groups of 10000 years ago.  My own apartment complex in East Lansing has the ability to house dozens of people in an area that lacks sufficient natural food sources for the population.  Modern developments have allowed human beings to evolve from hunter gatherers to farmers to city dwellers.  Farmers now make up a mere 2 percent of the population in the United States, a nation of roughly 300,000,000 people.  All of this change has happened in only about 10000 years.

It is also fascinating to consider the effects that environmental contamination and man-made toxins will have on the biology of humans.  Every day, we eat and drink food products that have been “enhanced” by chemicals.  Needless to say, I believe that if someone from the past who subsisted off of natural foods were to eat some of the processed food from a modern grocery store, they would have a bad biological reaction to it.

In short, humans have evolved a great deal in the past and continue to do so today.
