Welcome to Week 10! We are nearly at the end of this Science journey! Each topic every week has been so cool to learn about in more detail and this week it was the abiotic and biotic factors in human evolution. I wanted to better understand biotic and abiotic factors so I watched this YouTube clip to help me get a better understanding. I may even use this one in my classroom too!
My understanding is that biotic factors at the living things in an ecosystem, where as abiotic factors are the non living parts of an ecosystem.
We looked further into our own body and evolution through a documentary called 'Origins of Us', presented by Dr. Alice Roberts on BBC. This really interested me. From being involved in this Science unit I believe I have developed a greater appreciation for the world and other life forms around us and I think I just enjoy learning about it more as a result, which is why I thought some of the points presented by Dr. Alice Roberts were fascinating.
Some of her ideas and facts presented in the documentary is that our bodies and brains have evolved into the way they are today all because of food. The way we gather, cook and eat food are all contributing factors to our appearance toady. For example, our teeth have gotten sharper and more flat for the purpose of chewing through tough meats. Here is a picture to show the difference between an earlier species of life, compared to us homo sapiens.

Scientists have been able to discover the types of foods that were eaten by our ancestors by looking at an annoying little animal, the tapeworm! Did you know the tapeworm that is found in humans is the same as that found in lions?
Finally, another topic I took interest in was when Dr. Alice Roberts traveled to learn about the lifestyle of the Hadza people. They live in mobile camps and move around every 2-3 months, imagine moving to a different home that often! The Hadza tribe live a lifestyle similar to our earlier ancestors, being that they only eat the food they can find. They don't have any supermarkets, gardens or farms to get their food, they must hunt it. The men go off to hunt while the woman often gather roots and plants to eat. What a different lifestyle to our own!

Thank you Jenny for a wonderful week of insight! I loved learning about this topic. It'll definitely be something I teach my future students and hopefully you might too. :)
