Speciation and Macroevolution
A common challenge to evolutionary theory is that while life does indeed change over time (what is known as microevolution), no one has ever seen one species evolve into another species (macroevolution).
If the tape was rewound and evolution started over from scratch, Conway Morris says, the evolutionary details would be different, but the end result would be similar: a species characterized by intelligence and complex civilization.
In this paper, Venema explores several examples in biology where random mutation and natural selection have indeed led to substantial increases in biological information. The question of how new specified information arises in DNA, far from being an “enigma”, is one of great interest to biologists.
