Alternative Fuels

One new and upcoming fuel source that is being developed and used is the production of Bioethanol. This is a renewable form of ethanol that can be made from agricultural products such as corn, sugar cane, and potatoes. There are a lot of upsides to this fuel. There are some concerns however. The fuel is renewable source and considered "green." Some of the downsides and cons associated with this fuel are the increase in food cost. If crops were to start being used for fuel as well as food then the demand for these crops would rise and probably drive up the costs. There is also a concern for the balance or energy and pollution that comes with the production of bioethanol. Another con is that this process can have excess wastes that are largely useless. There is research being done into uses for the waste. One example of this is using different types of grasses to make the fuel and then using the waste produced to make things like paper.

Amphioxus

This small organism known as Amphioxus, or as Lancelet is believed to be the precursor to modern vertebrates. This is believed because this organism has been around for millions of years. It has a basic structure but it has many of the basic parts that set apart vertebrates from other organisms. Its basic structure and its old origins have led to the belief that it is an early basis for what evolved into modern vertebrates. Another characteristic that supports this theory is the study of the Lanelet genome. When studying the genome scientist find that it is by far the most basic chordate identified. This means that it was the first to split from the common ancestor from all chordates that predates the Cambrian Era. It being the first split shows that it is the origin of today's vertebrates.

Mitochondrial Eve

There is a belief and theory that all people have a common ancestor in a figure known as, Mitochondrial Eve. This woman was believed to live somewhere in Northern Africa. From her offspring was the basis for all of the world's population. As the population is this area began to grow different groups began to migrate to different areas. As these people migrated over time they began to develop differently based on their new environments. This is why people of different races look differently even though they all have a common ancestor.

Below are examples of how people have developed differently, and the different characteristics of different races.
