I dont see any proof of it.
You have the bones of extinct animals. That only proves that some species is now extinct and no longer on the earth. We have seen many species either teeter on the edge of extinction or become completely extinct. However, that does not mean anything has evolved into another species.
I beleive that some animals may be going through something like natural selection. Basically some animals with better charcteristics may be more adept at surviving when changes or harsh conditions of their existing environment change or get worse. Naturally these animals are the ones to add their unique genetic pattern on to the next generation. We breed animals for certain types of activities or for a food source. Horses have many breeds which we may call sub-species. However, we often cross breed horses in an attempt to arrive at a new breed or try to breed horses for a desired characteristic, like herding cattle, pulling wagons, miniatures, strength, tolerance to heat or cold, etc. I dont look at this activity as evolution. The horse is still a horse.
I think we may be able to become more adept at how we study the origins of life and this may bring to life new methods to study where exactly life originated and how life changes through time. I am open to ideas but I see no concrete proof of evolution. It is a giant leep of logic with no basis for a scientific conclusion.
I studied statistics at school and I know better than to assume what some pattern may appear to indicate. Often we dont find what we are looking for because there is no direct correlation between two events because some outside events are the cause of the outcome. Even our technologies for dating material can not be trusted. I think they are flawed.
