Macroevolution is definitley provable. How do explain the huge similarities between ape and human DNA? Also, fossils from farther back in time are adapted to different conditions that the bones of animals today. It is obvious that they had to adapt to their changing surroundings, and therefore, very slowly, they became the race that is on earth today. The bones of dinosaurs such as pterodactyls are remarkably similar to those of modern birds. To men, there is no other way to explain those similarities and changes other than macroevolution. Also, if we were to go back in time, we would see that there were less species than there are today. It is my belief that if we were to go back in time to the beginning of all life, it would start out with one type of bacteria or one-celled organism that came from an asteroid in outer space and landed in the waters of the ocean. From there, the organism adapted to the water, then ran out of food there, so had to grow legs and travel to ground, while others stayed in the water. From there, some stayed in water, others stayed on land, and still others adapted even farther to take to the skies. The land creatures separtated into dif. categories, including reptiles and mammals. The mammals evovled and the apes came around. The apes adapted even more, grew larger brains, started walking on two legs, and began building tools. That is where we came from and that is how we are all connected.
