Nope sorry. There is no scientific evidence that a species can change the number of chromosomes within the DNA. The chromosome count in each species is fixed. For this reason a male from one species cannot mate successfully with a female of another species. Each species is locked into its chromosome count that cannot be changed. If an animal developed an extra chromosome or lost a chromosome because of some deformity, it could not successfully mate. Again I think my point stands and is valid that belief in the the unproven is evident even in science.
Please do yourself a favor and stop bringing up the Catholic Church and what they have supposedly done or havnt done. They by no means speak for all Christians and is why I ignore your references to that.
actually there is...within our (human) DNA. genetics and elevolution show that we came from apes, and we share more than 90% of our DNA with chimps. you can find those anywhere. what is LESS known (because scientists admittedly dont say much about their discoveries to the general public) is that we have less chromosomes than chimps and other apes...yet we descend from them (through common ancestors). how can this be?
well the reason is that 2 of the ape chromosomes merged! thus changing the number of chromosomes (mutation), yet we are here! so we can reproduce just fine, right? theres your proof that it can happen, and has happened.
heres Kenneth Miller talking about it (a christian AND scientist...and a brilliant man!)
