On the Irreducible Complexity of Sperm Cells
Human reproduction is perhaps the quintessential example of teleology in biology. The process by which a fertilized egg develops into an infant over the space of nine months reveals exquisite engineering and ingenious design. Before this intricate process can even begin, there is a need for a sperm cell to fuse with an ovum — each carrying, in the case of humans, 23 chromosomes. This incredible feat bears the unmistakable hallmarks of conscious intent and foresight.
