No we haven't lost everything that makes us a fish. We retain many characteristics. Bi-lateral symmetry, laryngeal nerve, eyes evolved for water... why am I even saying this you should know all this.Xamonas Chegwé wrote:No. The line exists. It is only ever hard to define in the borderline cases. We are not a borderline case. We are not fish by ANY definition of fish. We have not merely lost the gills, we have lost everything that makes something a fish.Animavore wrote:Why are you using a self-serving defintion of fish which looks at the differences and ignores everything that's the same? We're fish that lost its gills. Big deal. There are cave-dwelling lizards who have lost their eyes. Have they stopped being lizards? Birds have wings where dinosaurs did not and lost teeth to boot. Have they stopped being dinosaurs?Xamonas Chegwé wrote:Ok then.Animavore wrote:No. That makes no sense what-so-ever and the logic is not the same.

Saying that our ancestors are extinct therefore we are exitinct is like saying my granddad is dead therefore I'm dead.
We have ancestors that were gill-bearing aquatic craniate animals that lacked limbs with digits. Does that mean that we have gills and lack digits? If not, how can we be fish, seeing as that is the definition of a fish?
You're trying to create a divding line between our fish ancestors and ourselves which simply doesn't exist.
The line does not and cannot exist because there can't be a single moment where you have fish on one side and amphibans on the other.
