Eli5 – Why do certain animals have such muscular physiques without working out?
In: Biology
Because their life revolves around survival as opposed to sitting inside and playing video games and being lazy. There’s no opportunity to be lazy. If you’re hungry, work. If your partner/”tribe” is sleepy, you’re staying awake and vice versa. If your territory is impeded upon, fight. Etc etc.
Their day-to-day lives are workouts. Humans, out domesticated animals and our pets are the only species that don’t have to exert much effort in outer day to days.
Some is genetic… they have a genetic mutation that produces or doesn’t inhibit myostatin (muscle-building gene). Sometimes this goes crazy and you get the Belgian Blue cattle.
It is a combination of lifestyle and the trade off for humans evolving larger brains was a bigger energy consumption, this means we have evolved to become less muscular
Many wild animals spend hours hunting/running/searching for food every day. But, which animals are you thinking of?
