Hooby let's look at the options.
Remember first that there are lots of ways to make a working Cytochrome C molecule AND you can take any one from any species, transplant it to any other species and it works perfectly. This is due to 'protein functional redundancy'. The important thing about the molecule is its physical shape and there are trillions of trillions of way to join amino acids together so that they fold up into that shape.
Option 1 - God created every species with an identical cytochrome C amino-acid sequence.
Option 2 - God created every species with its own unique cytochrome C amino-acid sequence.
Option 3 - Every species evolved from a common ancestor.
Imagine we now compare a human, chimpanzee and yeast cytochrome C amino-acid and nucleotide sequences.
What would we expect to find in each of the three scenarios?
What do we actually find?
I'm heading out for the day but I will check your homework tonight. No TV until its finished!
