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).
I fear that many of us ask the wrong questions about the beginning of the book of Genesis. Not only does this generate needless confusion and division, it also makes us miss the life-changing truths that we could see if we asked the right questions.
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.
