; babies begin cooing and gooing between 2 and 3 months, speak single sound words as early as 6 months, and put together short sentences by 24 months. He also shows many of the same experimental tendencies we see in human infants, such as repeating a behavior andWhile nowhere near the snail speed of Yoda life history, humans are also known for having slow life histories relative to many other species. We live for many decades and have long periods of infancy and childhood dependency .
Scientists suspect that adorable appearances and charming behavior are essential because human infants are altricial, meaning they cannot move around or care for themselves after birth.have posited that we should really think of human infants as “extrogestate fetuses” for the first three months of life, since they are so completely helpless without an adult, and they remain dependent on adults for several years.
An infant’s cute features and sociable behaviors make them appealing to adults at a time when they are totally dependent on others for survival.Being cute, whether in appearance, behavior, or both, is therefore advantageous. It encourages people to take care of an infant, despite steep costs, such as long sleepless nights or—in the case of Mando and Baby Yoda—the pursuit of dangerous enemy bounty hunters.
