And why do you start every thread born new, knowing nothing? What's the matter with you, boy?
The problem is that one is two teeth from South America and the platypus has no teeth. Tell me how did that lineage get established? Through evo-super molecular analysis of non-existent DNA? Also, kindly tell us the proof that these species had the following traits:
1. the mammary glands.
2. the egg laying.
3. your 3 earbones.
4. the poison spur.
5. the duck like bill.
6. the webbed feet.
7. the toothless mouth.
8. the electro-sensor in the bill.
9. the fur.
10. the cloaca.
11. the ability to vocalize and make different sounds.
In addition, if you insist that those teeth had the traits mentioned, then you need to tell us from what specific species these Obdurons got the above traits.
