A documentary about parental care in the animal kingdom Today morning I decided to turn my cable TV language setting in order to improve my English listening skills, after that I looked for something interesting to watch. And I found a documentary about the evolution of some species. It was specifically about cichlids and chimpanzees. Apparently, the cichlids evolved in 500 different species while the chimpanzee in three more; the human being was in one of those groups. At the beginning I thought it was a little bit strange to compare a mammal with a fish, but it made sense after they showed some behaviors in common between these animals. For example, both animals have an amazing parental care with their descendants. Chimpanzees are good at playing with their offspring and the cichlids tend to be very protective. I was surprised of the importance the cichlid male had. The female has the responsability to take care of the offspring, retaining them inside of her mouth, this is called by scientists as "mouthbrooding", she pick up the eggs they spawn and after a certain amount of time, she transfer the offspring to the male. And while one of them is incubing the offspring, the other is resposible to guard from another fishes. I found this quite interesting, because cichlids have a biparental system to take care of their descendants just like the human being and chimpazees. With respect of chimpanzees, the offspring have a white tale that indicates to the adults that he is still "a kid" and also allows some behaviors like beating or scratching others. When they lose their tale, the descendants can be discplined by their parents. Just like children, there is a point when the parents know when they can to discipline them.
