Also finally, in the question I have pointed out three facts(in bullets), to which one do you agree as the reason behind this process or could your suggest a new one. :) | |
| Mar 10, 2015 at 9:28 | comment | added | Williham Totland | @Jay The statement "The lineage of X split in two: One branch that leads to Y and one branch that leads to Z." is equally valid for literally any known living things X, Y and Z, which is largely the point of the answer. The details of which creatures are descent from which really aren't important to this answer. Besides all of which, whether we are descent from sharks is really a subjective matter: If you follow the lineage of sharks backwards, parent-to-parent-to-parent you'll find that it's damn hard to place a hard line on where 'early jawed fish' end and 'sharks' begin. | |
| Mar 10, 2015 at 9:19 | comment | added | Jayachandran | " the lineage of sharks split in two: One branch that leads to fish, amphibians and eventually dinosaurs, squirrels and dolphins, and one that leads to sharks". Here do you meant the shark instead of "Cambrian early jawed fish". | |

| Mar 10, 2015 at 8:06 | comment | added | Jayachandran | "The shark, our ancestor" can you provide some reference for your claim that fishes are evolved from sharks. Also there is no reference for any of your claims, so how can I accept your answer ? | |
