This is like dogs walking down stairs on the front legs. You immediately concede but minimize this: "Just make some qualitative adjustments". Yeah, some, like a completely different pelvis and lower musculature. If you're going to answer the biology, you should be accurate. | |

Some other members of the family Agamidae also exhibit bipedalism but lack the distinctive frill (such as Physignathus cocincinus, commonly known as the Chinese water dragon), and there are other genera outside of that family that do as well (possibly most famously the members of the genus Basiliscus, commonly known as basilisks). | |
| Feb 21, 2023 at 12:32 | comment | added | Daron | @KevinKostlan I suspect the frill acts as a sail to push the upper body off the ground. The lizards people will need to be modified to have some weight shifted behind the COG to exert a comparable force. | |
| Feb 21, 2023 at 8:11 | comment | added | Kevin Kostlan | Does the balance depend on air friction? Where the lizard can adjust the area of the umbrella in order to prevent falling forwards or backwards? | |
