Causes of evolution

The causes of the evolution - Have you ever asked yourself why it developed or unfolded in the first place? the story evolution is already a few years under its belt, because humans were already concerned with biological processes in antiquity.

The causes of development

• The theory of evolution says that a single cell became a multi-cell so that certain tasks could be solved. As a result of this "specialization" of the individual cells, they required additional cells. Invertebrates emerged from the multicellular cells, followed by vertebrates, followed by reptiles and finally dinosaurs. After their extinction, the species suddenly became more and more intelligent.
• The British naturalist Charles Darwin (1809 - 1882) explained the process of development to himself, among other things, through natural selection and common ancestry. Adapted animals could reproduce, others were doomed to extinction. This applied not only to physical strength, but also to illnesses and the ability to regenerate.

• Another possible cause of evolution is what is known as genetic drift. Each population is endowed with specific genes. If a population now separates, one half no longer has all the genes available. In this way new species can emerge.

Examples of evolution

• The evolution of viruses and bacteria can be observed in fast motion. If antibiotics still help against flu one year, it may look completely different the next year. Because the viruses or bacteria develop resistance to the chemical remedies.

• According to some theories, if there were no evolution we would still be single-cell organisms. And if natural development would proceed more slowly, we would still run through the forest with clubs today.
• Have you ever heard of the Galapagos Finches? These animals are very interesting because when the food supply changes, the shape of the beak adapts to the circumstances.

The causes of evolution do not always show up in a positive development. Unfortunately, however, it also leads to the extinction of individual species or it gives rise to hereditary diseases.
