Cute alpcas captured by my cell phone camera.
One of the features that humans find inherently cute is large eye size in realtion to head size. Alpacas have very big eyes, which is part of the reason they are so cute. Scientists conjecture that the ability to discern cuteness is an adaptation that makes us want to take care of babies, who, like alpacas, have large eye to head size ratios.
Alpacas are a domesticated form of the wild animal called the vicuña. They, along with llamas, are related to camels (two humps) and dromedaries (one hump). All of the existing camelid family had a common ancestor in North America, which spread to South America and Asia, but then died out in North America. Over time, humans have domesticated the wild forms, leaving us with alpacas, llamas, and camels today.
