Communication is the important phenomena that helps in the interaction between the people. Communication can be done in the form of language, signs and gestures.
The communication gap between the parents and children might creates a problem in their relationship. The parents should talk politely with their children if they do not want to talk with them. The parents should start communication with the topics in which their children are also interested. They should ask them about the children daily routine and their friends.
Darwin’s theory became accepted because it had more evidence that supported it. Lamarck’s theory suggest that all organisms become more complicated over time, and therefore doesn’t account for simple organisms, such as single-cell organisms. We also know through observation that characteristics inherited during an individual’s lifetime do not get passed onto their offspring; for example, if someone pierces their ear, it doesn’t mean that their children will be born with pierced ears. Darwin’s theory became even stronger when, many years after his death, the study of genetics emerged. Genetics ultimately showed that all inherited traits were passed on through genes, which are unaffected by outside world, as Lamarck would predict, and are instead naturally varied, as Darwin predicted. Though Darwin didn’t know what genes were, he could see their effect on natural selection.
