Ответ: All life forms on earth are evolving continuously. Changes in the genetic material of animals, insects and plants can eventually lead to the creation of new species. In most species, two sets of genes from the parents combine at the reproduction stage to create a unique offspring that is not identical to its parents. Genetic variation happens randomly. This is important in order to increase the chance of survival and further reproduction. The species adapts itself to environmental changes in this way. Over time, helpful characteristics become more common and unhelpful ones disappear. This is part of the process of natural selection. We all inherit our characteristics from our parents. How this happens is of constant interest to evolutionary biologists who carry out the work of developing and testing theories of evolution.
