00:00Why the biggest dogs live less?
00:02This is science.
00:04While a big Danese has a hope of life between 8 and 9 years old,
00:08a Chihuahua can easily reach to 14.
00:11A very big difference if we consider that they are of the same species.
00:16But why is this happening?
00:17Experts from a university in Australia examined the causes of the differences in the hope of life of 164 species.
00:25According to this research, the big dogs do not necessarily grow with faster speed than the small ones.
00:33However, the increase in weight and size does significantly increase the causes of cancer.
00:40According to scientists, this could be explained with the theory of aging,
00:44known as optimization of life history or Soma desechable,
00:49which says that if an individual intervened in the most part of his energy in growth and reproduction,
00:55they will not be able to apply it in the cellular reparation and defense against cancer.
01:00Although the results of this study may be dangerous to the owners of big dogs,
01:05the researchers also predict that these in the future will evolve to develop better genes to combat these diseases.
01:14You have to take into account that the majority of the dogs that exist in the actuality
01:18have very few years, so they really do not have time to incorporate mechanisms of defense against certain diseases such
01:27as cancer.
