1. Life on Earth began with simple chemistry. But the simple chemistry was not simple. In fact it was very compicated. Life was made from an RNA strand with the code ACUG. A was made through a recipe of life. Part of it joined together on the ground and then it evaporated. When it came down the part joined joined with the other part making A. When A was exposed to sunlight it became U Simple ingredients made these too parts of RNA we just have to find out how C and G were made and then we know how life started.
2.In the evolution in action game it shows clearly how evolution works. If the environment changes to quickly then they cant adapt and they will all die. If they are clumped together they wont be able to feed themselves and they will all die. If they are too isolated they wont wont be able to reproduce well. Without reproduction their species cannot thrive. Only in the right conditions can humans and animals adapt reproduce and thrive. Also genetic variation plays a role because 20 percent of the time a mutation occurs.
