Creator has invited human scientists to study the squirrel to get insights into the nature of energetics, and how the squirrel marshals energy to run up and down trees all day with graceful effortlessness. Given how small and wiry the squirrel is, it seems impossible that the squirrel could get all the energy it needs from its food intake alone. Before ET alteration of the human genome, were we more like the squirrel than we are now?

You have never been squirrel-like in this sense because there was never a need. You do not have the same physical demands as the squirrel to live in such a habitat. Your intelligence and your intuitive reach are the means through which you prevail quite nicely in your habitat. This is simply a difference in the biochemical nature of energy generation and conversion. There are discernible scientific explanations for the energy creation and utilization within the muscles of the squirrel that differ from human and hold the key to understanding their high efficiency given the many challenges in their environment to have enough food, and so forth. But it is the nature of their makeup that not only can they produce prodigious feats of strength and stamina, they generate energy much more efficiently than most other animals, humans included. So they simply have an innate advantage in that regard that serves them given their habitat and the lifestyle they are suited for. It is one of many variants throughout the earth plane and the makeup of organisms and the quite wide variety of strategies used to provide what is needed for their propagation and to help them thrive under all kinds of unique environmental circumstances, some of which are quite harsh. So this is more the end-stage utilization of the life force energy as well as self-generated energetics from food intake, and so forth, rather than totally life force energy and its manifestation differing among these examples.
