Temperate deciduous forests are found in the middle latitudes around the globe and have four distinct seasons: Spring, Summer, Fall, and Winter. During the fall, trees change color and then lose their leaves. This is in preparation for the winter season. Because it gets so cold, the trees have adapted to the winter by going into a period of dormancy. A forest has many layers of plant life. There are the small plants such as shrubs, moss, ferns, and lichens which grow quietly beneath the shadows of the tall trees.

Every woman alive today received her mitochondria from her mother. If we trace the passage of the mitochondria back one generation to the mothers, we have fewer women than today. If we trace back another generation, we find an even smaller number, and with each previous generation this number decreases. Eventually this traces back to a single woman from whom all women alive today received their mitochondrial DNA. Mitochondrial Eve lived approximately 200,000 years ago. It is believed that she lived in Africa and from her all of the tribes of the world were created. Although, many races developed after some of her descendents migrated to other regions, all races have a connection because of this common ancestor. |

The Butterfly Effect
The Butterfly Effect is an explanation of how unpredictable large systems can be because even small changes can can have large ramifications. The name The Butterfly Effect itself draws from the notion that something as simple as a butterfly flapping its wings can change the wind patterns enough so that it may eventually cause a tornado. The Butterfly effect is also named the Chaos Theory because with such massive events theoretically stemming from such minute phenomena, it is impossible to predict anything that is effected by The Butterfly Effect.
