Genetic and Anatomical Variation among species
Earth Day 2014! Today is a special day for our planet... many people today will begin to see the change they can make to not only our local communities and ecosystem, but the larger biosphere as a whole. Volunteers around the world will increase their recycling efforts, plant trees, and educate people on their individual human impact on the environment. As part of our unit on Evolution and leading into our next unit covering Ecology, we listened to a TED Talk by George Monbiot titled "For more wonder, rewild the world". His take on rewilding certainly brings to light many conversations about not only the human impact on the environment, but also the many species that inhabit our planet. In his talk, he discusses the impact of the wolves in Yellowstone National Park as well as the whales in the ocean. Their impact as a species is tremendous in maintaining a balanced ecosystem! As part of Earth Day, our classes took advantage of NASA's #GlobalSelfie request and went outside to snap a picture and soak up some Vitamin D!

Natural Selection How does the series of events (1-4) depicted in the image to the show the progression of natural selection? As noted in your simulation packet, there are three conditions for evolution being demonstrated... can you identify all three? We will discuss these driving forces in further detail tomorrow during class - your job is to identify them before class! Natural Selection
What Darwin Never Knew... In 1859, Darwin published his theory of natural selection in On the Origin of Species. This was ground breaking work that theorized that organisms have and always will continually change based upon responses to their environments. Now, 150 years later, scientists and researchers have been able to confirm many of Darwin's findings through genetic research. When Darwin made his first initial observations, he did so only using his eyes... not knowing the depth and complexity of our genetic identity. Now, we have the ability to study the DNA sequences and its many genes to see the evolutionary changes at the genetic level! What's important to remember is these evolutionary changes - such as developing limbs or the change in human height - occur over many generations based upon the survival of the "most fit" individual in the environment.
