This article is about scientist that have found a new earth like planet in a near by solar system. Gliese 581g is located  some 20 light-years away in the "Goldilocks zone". The telescope that found was in Hawaii. A quote from one of the scientists is "The fact that we were able to detect this planet so quickly and so nearby tells us that planets like this must be really common." Which i think means that there has to be at least one with aliens on it. Gliese 581g has a mass about three to four times that of Earth. It orbits its sun in 37 days and is thought to be a rocky world. It  also has enough gravity to possibly have an atmosphere.

I decided to share this article because we found new earth like planets near by. This opens so many possibilities to our kind, human kind. In class we are learning about great civilizations and there might be great civilizations on this planet too.

This article is about scientist that have found to two new fossils of giant plant-eating horened dinosaurs. These dinosaurs were found in the southern part of Utah.The scientists say the new found dinos lived in the subtropical swampy environment. These new dinosaurs were the cousins of the Triceratops. They belong to a family known as ceratopsians, ceratops means  horned face in Greek. The two dinosaurs were Utahceratops gettyi which had large howrn over its nose. The other one was named Kosmoceratops richardsoni, it had atotal of 15 horns on its head.

 I decided to share this article because it is interesting  that they found two new animals that were never known until now. This relates to what were learning in class because we are learning about early history, and this is something in history we did not know until now.

Map Question 1- Europe has the earliest agriculture sites.
Map Question 2-The Geographic Features that favored the development of Agriculture sites before 5000 B.C. were the rivers or rivers near the site.

   This video focuses on Ethiopia were Lucy was found. Lucy which was the first and oldest skeleton found in ethiopia was discovered in 1974. archaeologists estimate she is around 3.2 million years old. She was a Bipedel  which means she stood up on 2 legs like a human. Humans began to evolve in Africa.

   Hunters and gatheres were on the move alot because the were following a herd of animals which also makes them nomads. While they were on the move they collected nuts, berries, and greens to eat. I personally think Lucy was a gatherer because she was a woman and the women gathered berries  nuts and other things to eat.

    An absolute location is the longitude and latitude of a specific location on Earth. For example Los Angeles would be 34 degrees north latitude  and 118 degrees west longitude. Another example is Paris,France, that would be 49 degrees north latitude and 2 degrees east longitude. Capetown,South Africa would be
34 degrees south latitude and 18 degrees east longitude.

  relative location is when you locate something by the things around it. For example London the capital of the U.K. is located on the thames river  a major water way. It is possible to do this with anything. For example Queens,New York is located between Brooklyn and Bronx.
