Dog. Evolution of dogs is linked to starch digestion: Researchers from Uppsala University have compared the whole genome of dogs and wolves to reveal that many changes have taken place in the evolution of wild dogs into man's best friend.
Unsurprisingly, many of these disparate regions affect the brain, which may explain the differences in temperament between wolves and dogs. In addition, this comparative study points to several areas involved in digestion, including genes that help break down starch.
Researchers say it is possible that dogs have self-domesticated by finding humans and eating human leftovers. Israeli fossil and genetic research has identified the domestication of dogs as about 10,000 years ago, coinciding with the Agricultural Revolution, when humans transitioned from nomadic hunters to farming and living in settlements. Some scientists believe that wolves were attracted to the garbage dumps of these early settlements, feeding on vegetable and cereal plant leftovers.
Prior to this, in 2005, the research team published the complete domestic dog genome. After the completion of this project, the researchers turned to studying the evolutionary history of dogs at the genome level.
The researchers sequenced the whole genome of 12 wolves from around the world, as well as 60 dogs representing 14 different breeds. They searched for evolutionary markers by looking for sequences that showed the greatest differences between dogs and wolves, or sequences that were consistent across dog breeds and differed in wolves. The result was a list of 36 regions with a total of 122 genes.
Half of these areas contain brain genes. There are 6 regions and 10 genes associated with fat and starch digestion. Specifically, dogs carried extra copies of the amylase gene compared to their wolf counterparts.
In addition, dogs produce 12-fold more maltase-glucoamylase because of several mutations in the enzyme gene. Mutations in the third gene, SGLT1, improve the absorption of proteins by intestinal sugar. [2]

Hello, the answer is rats.
Although the Rat has an innate ability to foretell danger and thus stop in moderation, because you never miss the opportunity to bargain and make a "good deal", it is often difficult to make accurate decisions and end up falling into a trap. As the saying goes, "only by eating a trench can you grow wiser", in the life of the rat people, before they understand that greed is harmful and useless, they must suffer at least one big financial blow. However, it is impossible to find a destitute rat man.
If others can find it, then we can bet that the rat people will not be poor for long because of their ability to adapt to change, otherwise, the rat people are not the rat people. If the rat people can overcome their greed and learn to be tolerant, then the road to life will be smooth.
The magic of the rat man's personality is as universally loved and understood as Walt Disney's Mickey Mouse. On the surface, rat people may appear to be reticent, but in reality they are not. Your heart is never as quiet as you appear.
Actually, rat people get excited easily, but you can control yourself. This is the best explanation why the rat people are popular and have many friends. Nezumi people may be frank and honest, but your friendly actions often make others feel reserved.
The Rat people are usually cheerful, happy, and sociable. Occasionally, you may come across a rat man who loves to criticize, complain, and nitpick.

Hello, the answer is horses.
Friends who belong to horses represent noon in the twelve earthly branches, and noon horses rank seventh in the twelve earthly branches. Horse friends are melancholy by nature, and they look decisive and bold on the outside, but in fact, they are reluctant to share a lot of things in their hearts. The reason why they are susceptible to "depression" is because they have a strong heart in their hearts, unwilling to admit defeat, and will choose to seek death and life when they have a sense of failure and frustration.
