How do cities influence evolution?
Blue pigeons were domesticated at least 5,000 years ago in Asia as a source of meat. Over time, they returned to freedom – but did not leave the settlements, which turned out to be an ideal place for them to live.
Every day we associate evolution with a long process that cannot be seen with the naked eye. In fact, we can observe this in just a few generations. To do this, we don't even have to go deep into the wilderness, it's enough to stay in the urban jungle.
Forward, evolution!
Evolution is often spoken of in the past tense as a phenomenon that resulted in the current (and extinct) species of plants, animals, fungi, etc. Let's add that most of them have already appeared thousands or even hundreds of thousands of years ago. Therefore, it is easy to give the impression that this process no longer works.
In fact, this happens all the time in the present tense. Evolution is nothing more than a change in the frequency of occurrence of these varieties of genes in a population from one generation to another. One of its side effects is the formation of new subspecies and species. The existence of the latter is said that after some time the sum of accumulated differences between the genes of several populations does not allow them to jointly produce fertile offspring.
Thus, new species do not arise overnight, but as a result of the gradual divergence of evolutionary lines. Although it takes time, we can observe some changes even during our lifetime.
Urban jungle.
The process of evolution itself is meaningless. However, which alleles will be preserved in the next generations will depend on their adaptation to the conditions in which they found themselves. Organisms with features less adapted to the environment in which they live are less likely to produce fertile offspring — according to statistics, there will be fewer and fewer of them. And vice versa, if their genes allow them to adapt better to existing conditions.
Therefore, the preferred functions will depend on the environment. In addition to climate and geological processes, an important factor affecting the environment is the activity of other organisms, including humans. We are constantly changing the environment through commercial activities and the construction of large estates.
