The Fingers 8 and not 10, the front of the Fingers are on both bigger the Finger self very slim but powerfull
Gastrotheca guentheri have teeths so the genetical Information is already in Frogs to get some,
The rest of the Body could fit too if we go farer in some amphibians Evolution, slim Body but better Bones and Muscels, the dark bigger Eyes.
Metamorphose could explain why they understand more about Genetic.
It also would say the World they live on had more *Water*.
Naturally it`s just a guessing, we are not far about the own Species and Hystory.
About Frogs
German link:
Some chinese Frogs use Ultrasonic to communicate
Frequency till 100kHZ, this are Frequencys you can `t hear so maybe hear better and not bader.
It`s maybe not even so crazy to believe in that.... Amphibians are older then Apes.
