Evolution is either a fact or a thoery to different people. People with strong religous beliefs tend to stray away from the thought of organisms (dogs cats humans elephants etc) deriving from bacteria billions of years ago. But with others that are open to scientific theory thoughts and may still be a bit religous, who knows, they can see that organisms may have been developing over time. It's hard not to accept facts, and artifacts that have been found to prove such theories. With evolution, certain attributes occur in a relatively short period of time. This is called micro(small)evolution.
In micro evolution just judging by the name you can probably tell what it is. It is the small or minuet changes in an organism to evolve. Its more of an adaptation than the evolving of a creature. for instance micro evolution includes a rabbits fur changing to white in the winter to hide itself from hungry wolves. It could also be a beetles' resistance to pesticides increasing. Microevolution is a wide variety of small changes that benefit the organism in its' day to day life activities.
Micro evolution is also known to happen fairly quickly. In mice that have new foundedly settle in black lava rock, they already begin to evolve. What they do is go from what ever color they were whether it be white, or brown, they begin to turn black through their kids. It can happen quickly for the mice to avoid being eatin by other predators suck as hawks that will see them from the air. Micro evolution is pretty much adaptation of a species to their environment.
On the other hand there is evolution that takes longer to be completed. For a great example, humans. We humans took a very very long time to be completed and are still in the making. Billions of years ago there was an ape-like creature that walked, or rather crawled on four legs/arms. 2 arms up front and 2 legs in the back. Now today, we humans walk on just 2 legs with ease. This is macro evolution. A fine example of it as well. Macro(large)evolution takes a longer time to complete or can be some what never ending in some cases.
In the 1800s when "honest Abe" was president he was considered to be a tower. A very tall person. But he was only 6' 1". Today we have people like Shack that are like 7'3". Humans are still evolving. in my opinion. Brains are possessing more knowledge and bodies are capable of doing more that what once was thought of.
Evolution is a widely accepted theory and is very close to being complete fact. But The strict religious beliefs people have make evolution a joke. But, i believe that evolution could be Gods work:), think about it I mean, maybe human kind deriving from bacteria is gods work. Maybe, even the creation of bacteria is gods work. God could of even got rid of the dinosaurs as a prototype of life. Because of the fact that humans wouldn't be able to survive with dinosaurs around. The thought of Evolution is a very complex one with MANY artifacts that have been dug up in order to prove its reality. With Lucy's body being found, how can you not believe. Whether your a believer or not, you can't deny the cold hard proof.
