Cats, with their blind and helpless kittens are altricial. The other pattern is precocial. In this pattern the offspring are usually born single and from birth the young are able to get around quite well. They are alert and all their organs are functioning. An example of this pattern is the horse, the wildebeest,antelope etc., where the young will run with the herds within minutes.
Humans follow neither pattern.
We do not have litters yet our young are helpless and extremely immature. They do are unable to stand and locomote like precocial species. In 1941 Adolf Portmann, a Swiss zoologist, considered the quandary and suggested that humans are secondarily altricial. Portmann makes some powerful points about the extraordinary differences between humans and other precocial mammals. But newborn humans are incapable of assuming the species specific upright posture that characterizes their kind.
