You keep repeating the same thing over and over, yet nowhere do you answer the question. I am not asking why some giraffes have shorter necks than others. I want you to explain how the giraffe evolved from a non giraffe.
I don't know exactly how but I could provide a scenario that created other species, will that do?
Imagine the short-necked, short-legged, forest-dwelling ancestor of the giraffe inhabiting an valley that, due to volcanic eruptions becomes isolated from the others of its kind. The valley dries out and the animals that are taller can reach more food and survive more often. Over thousands of years the process continues until that short-necked, short-legged, forest-dwelling ancestor of the giraffe has become the giraffe we know today. Now the volcano erodes and once-isolated giraffe population spreads out and encounters their ancestors, still short-necked, short-legged, and forest-dwelling. The two population will not interbreed and are now two distinct species.
Each time you end up starting with a giraffe and telling me how it adapted to its environment. You have not yet explained how it evolved from a non giraffe.
When I said "short-necked, short-legged, forest-dwelling ancestor of the giraffe" how did you understand that to be a giraffe?
This is how it might have looked. Is this a giraffe to you? It wouldn't interbreed with a modern giraffe and would be considered a separate species.
If you object to the biological definition of a species please share yours.
