The answer is how quickly the body size is produced. We have found that birds and stars that reach large size reduce cancer spread. For example, normal dolphins, Dolphin Delphi Readed to reach the larger size of the body – as well as the other wheel and dolphins (which is called Settasin) Three times faster than other stars. However, Is the phenomenon of Settasin There is less cancer than expected.
Large species face more risk of cancer, but those who improve the mechanism developed to reduce the rapidly developed mechanism to reach this size, such as low mutation rate or DNA repair mechanism. So instead of contradicting the Coop Principle, Our searches make it better.
Large bodies are often developed, but not in groups where the burden of cancer is high. This means that the risk of cancer has shaped the speed of evolution.
Man was rapidly rapidly rapidly in our physical size. On the basis of this, we will expect that the spread of similar cancer will be spread in humans and bats, as we are produced at a very fast rate. However, it is important to note that our results cannot explain the actual spread of cancer in humans. Nor is it an easy statistics to estimate it.
Human cancer is a complex story that has many factors that affect the abundance of types and spreads. For example, many humans not only have access to modern medicines but also Different lifestyle Which affects the risk of cancer. For this reason, we did not include humans in our analysis.
To fight cancer
Understanding How the species is naturally developed There are important implications for human medicine in defense of cancer. For example, naked sesame rats are studied for this Spreading abnormally low cancer In hopes of exposing new ways to prevent or treat cancer in humans. In the mice, some cases of cancer have been seen in the mice, so their mechanisms of resistance to cancer are mostly a case.
At the same time, our searches raise new questions. Although the birds and stars that are quickly manufactured have strong cancer anti -mechanisms, the anti -cancerous mechanisms have not been the same as the embodiment and crawling animals. The spread of cancer was high in large species, regardless of how quickly they were ready. This may be due to differences in their regeneration capabilities. Some embebies, such as salamanders, can Create the entire organs– A process that includes an abundance of cell division, which can be exploited by cancer.
Putting cancer into an evolutionary context allowed us to show that its spread increases with physical size. To study this The racing of evolutionary arms Nature can unlock new insights about fighting cancer. And how can we do the same?
