Question for theists: accessory bones
Some people are born with 'accessory bones', extra bones typically found in their hands, feet or legs. It's easy to see how, as bones can become smaller or larger over the generations (people come in all shapes and sizes), and by sometimes adding bones, the evolutionary process can form all kinds of different skeletons. Generations born with particular skeletons which work better in some way over time will tend to be more successful and pass their skeletons on and that is how we inherited our skeletons, which are still changing a little as we see with accessory bones. Adult human skeletons typically have between 200 and 210 bones and babies have over 300 (many bones fuse together as they grow), some people even have an extra vertebra.
Why would a God make people with slightly different skeletons ? What are the alternative 'designs' for ?
