If a species becomes extinct, will a similar new species emerge long after?

There are species extinction all the time on Earth, and new species are born all the time, but we can't perceive their evolution.

The birth of a new species.

According to modern evolutionary theory, we know that species are constantly evolving, and the reason why we do not perceive evolution is because the process of evolution is very slow, and it takes tens of thousands or even hundreds of thousands of years to form new species. However, human breeding methods can speed up the evolution of organisms. About 10,000 years ago, humans domesticated wolves in various ways and turned them into dogs.

Over the next few thousand years, the dog's physiognomy changed less. But in the last century, human demand for pet appearance has led to the emergence of a variety of different pet dogs, although these pet dogs are all dogs, but they are different in size, appearance, color, etc. In biology, only two organisms that appear to be reproductively isolated will be called "new species", and from the current point of view, most dogs are still able to mate and give birth to offspring despite their different body sizes and characteristics, so most dogs are not reproductively isolated.

However, there is reproductive isolation between a small number of dogs, for example: the largest Great Dane and the smaller Chihuahua cannot reproduce offspring due to their size, and there is reproductive isolation, so to some extent, the Great Dane and the Chihuahua are two different breeds.

New species will appear. This is probably the disappearance of a species in a certain niche in an ecosystem, and there will generally be other species to fill it, and the species that will be filled will not necessarily become a new species, but may be competitors in the same ecological niche as the disappeared species.

I think to a certain extent, because nature is mutually reinforcing, and the extinction of one species will inevitably lead to the emergence of similar new species.

It is possible, depending on the reproduction in this area, as well as the emergence of new species, which requires species research.

<>1. There are generally two reasons for species extinction, one is natural and the other is man-made;

2. Natural causes: In the long course of history, some organisms will adapt to the environment and gradually evolve, while others will not adapt to the environment, and the number will decrease and even become extinct, which is the result of natural selection, many species are now extinct, and new species are constantly being produced at the same time;

3. Man-made causes: man-made destruction of the environment, human activities have destroyed the living environment of other organisms. There is also the fact that humans hunt other species for a variety of different reasons, causing species extinction.

The reckless introduction of new species from the outside world without sufficient consideration can sometimes greatly threaten native species, leading to the extinction of some species.
