- Bipedal animals are more energy efficient than quadrupedal ones.
- Being bipedal frees up the hands for a myriad of uses, whether it be for catching fish, striking prey, or climbing trees.
- History has proven that animals, once bipedal, tend to be adaptable...just look at dinosaurs, macropod kangaroos, leptictids, pseudorhynco...whatevers, and hominids
- Bipedal animals can rear up and browse on vegetation out of reach of their same sized but quadrupedal contemporaries
- Bipedal animals can look over underbrush or tall grass and spot predators and/or prey
Speaking of my early bipeds, I completed another size-chart, the therapeds. Go to our site's Size-Chart page and click on the Therapedidae. It's 2 pages long.
