Check out my new blogs

Due to the fact that my posts here show up as "Sandy"  I made a new blog were I show up as "Mrs. Jacobs."  If you want to see a few more updated posts check me out at Mrs Jacobs Biology,  Mrs Jacobs AP Biology, or Mrs Jacobs Forensics.

If you are a teacher I have an old blog Experimental Teacher and a new blog with another amazing teacher We Teach High School.  I would love to hear from anyone who is using these blogs for any reason.

Christopher McDougall: Are We Born to Run?

Human beings have continually evolved over thousands of years. Many wonder and question researchers, "How did we survive in the 1600s and anytime before that?" The idea is that we simply were born to run.

-Native American Indians

• Hid in Copper Canyon where they persevered through many years


• Free from modern diseases and illnesses


• If the oldest and first sharp object constructed specifically for weaponry originated 200,000 years ago, how did human beings survive before that?

-Ethiopian Woman Runs a Marathon

• Hasn't ran in eight years


• Recently nearly died in child birth


• Kept up with a professional runners

-Women in the Olympics

• "Too slow"


• Body type not suitable for long-distance running


• Woman finishes eighth in a forty-eight hour race

These examples give perfect reasoning to the idea that groups of human beings in early years hunted and survived like packs of wolves. We ran our prey to death. Groups of humans aging anywhere from twenty to eighty years old were chasing down dinner day by day. Running is a natural ability that replenishes pride in our ancestors' soul.

Interview with Dr. Ronald Evans

In this interview, Dr. Evans discusses what steps he took in becoming a professor where he now works. He feels that his job in studying the sciences of fat, or obesity, is what got him interested. He feels that his job is not a job, but instead something that he loves to do, believing that work should be something that interests you. He runs a huge lab and his wife studies neuroscience, while his daughter mastered art history. He loves to travel with his family and doing what he is doing now.

Interview with Katherine Sorber

She studies the parasite involved with malaria to help make a new drug that will last more thatn 20 years. Shel uses DNA, RNA and proteins and uses alternative splicing to take out RNA and study the geonome.

Learning from the Gecko's tail

Biomutalism is helping bilogist learn from engineering and nature. Gecko feet developed in a robert to climb on surfaces. The tail also acts as a 5th leg of stability and helps with air righting response. Together organisms and enviroment help perserve nature's design.
