Life on Earth assumes a large variety of shapes. There is plant life and animal life. Protozoa live alongside human beings, ants alongside fish and elephants, a blowball alongside a cactus.
\nAt first glance, the creatures living on Earth do not seem to have much in common. There are various manifestations of life in terms of characteristics and appearance. Is it possible that this impression is wrong? Is there something that all these creatures have in common in their internal structure? This is hard to believe if you compare a plant with an animal.
\nLet\u2019s take a look at two more creatures: an ape and a human being \u2013 what do these two species have in common?
\nIt is easy to find some differences and some similarities. Monkeys and humans have a similar body structure and similar limbs. In spite of that, we can clearly distinguish an ape from a human being. Where do these similarities and differences come from?
\nGenetics provides answers to these questions. It is the science of heredity. The term \u201cgenetics\u201d stems from the ancient Greek word \u201cgenesis\u201d \u2013 \u201corigin\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
