what is evolution?
According to Charles Darwin, Evolution changes every time, the process where modern organisms evolve from their descended ancient organisms.
what is the difference between fact and theory?
A fact are based on a true data based on an observation, while theory is a group of facts that needed explanations as to know why it works the way it is.
How do species evolve?
Species evolve over time, mutation occurs that give traits that help them to survive and adapt to the environment. This process is called Natural selection.

How do different species transform into different kids of forms? it is with the power of transformation, For example dogs. Dogs ancestry came from wolfs their fear are getting closer to humans due to stress hormones for survival instincts but some wolf do the natural variation have lower stress hormones that makes them less them afraid of humans. Back in the Ice Age era, where humans discovered clothing and agriculture, the wolves traded their lives to the human in exchange for stable food, humans select wolves that would protect and hunt and kill the ones that cannot follow orders, this is called artificially select, when you take characteristic/trade that you like and kill the ones you don’t. All living organisms came from one ancestor/ one single living organism that is why we are related to one another, like we are more related to a butterfly then we are related to a tree. Natural selection happen based of the environment where a living organism can potentially survive. For example the development of eyes for fish, first they didn’t even have an eye until a mutation happen to one single organism that create more fishes to have eyes. The eyes was first blurry and black and white are the only colors they can see, but vision developed over decades giving off springs and new generation of fishes better to see wether is to avoid predator, find food or avoiding corals and plants. Extinction happens because they compete with other species that have better skills to survive.
