“While the tails of sea urchin and human sperm share the same bendy inner core, the study suggests that the tails of sperm in mammals may have evolved a reinforcing outer layer to give them the exact amount of extra strength and stability required to overcome the thick fluid barrier they come up against in internal fertilisation.”
“have evolved” - remember all this complexity is just a ‘happy accident.’ Just give it a few million tries and this tiny detail could have evolved itself. Why at that rate, evolving to a complete human would only take a few billion, trillion tries.
And if you believe that, you are delusional.
A friend tells me, it is the same as placing all the parts for a 747 in a huge box, shaking well and expecting a finished aircraft.
Careful, all the atheists on FR are going to hammer you for mentioning God.
