Evolution: The Greatest Show on Earth

   Summary: This world is always changing. From the advancements in technology, to new culture and traditions. Yet none of those things could even exist if it wasn't for something way way before that. That's where the theory of Evolution comes in. Evolution is the theory that we all came from one single organism and that we continued to adapt to become who we are now. For example how they say wolves are the ancestors of dogs. The wolves got breed over and over again to make mixes of colors shapes and sizes. Then those mixes mixed. So on and so forth. This eventually changed the gene pool enough to make the wide variety of dogs we know and love today. In reproduction  when a  mom and a dad mate they give half of their genes to the child. This makes the child slightly different then both of their parents. This change is evolution. A change in the physical appearance is a change in the gene pool. This change can lead to advancements over time such as resistance to heat or smarter brains.

S&EP: Using Models: In class we did an experiment. This experiments were used to simulate how Mutations in the Evolution. For Mutations we have a certain pool of people that have a set of genes. In the simulation we used M&M's as the people. The different colors representing the different genes. Suddenly a mutation appeared. Mutations occur when there is an error in duplication when the genes are passed from parent to child. This mutations were represented by red hots. Now that Red hots were added to the gene pool there were more options to pick from. This changed our end result. Just like how in real life when a mutation occurs it can pass on further and further and more and more people can have it.

XCC: Patterns: If we look at the theory of evolution it is like a deck. The gene pool is just like the cards in a deck. You do always get 50 / 50 from each parent. Just like how red and black both take up half of the deck it is the same in evolution.  In each of the 50% each parent passes it will give you certain alleles. These alleles are you hand of cards you start off with.  Since it is mostly 50% 50% you can usually have an estimate what our gene deck will look like. Yet evolution is how our deck gets shuffled. This is when traits change. Either through Natural Selection, Mutations, ETC. This changes the balance of  the cards passed down to your children. If you didn't think Evolution matter, it's actually the future of this world!
