A century of problems, help me solve!!

Did the first chicken come first, or did the first egg come first? This is a mystery that mankind has wanted to solve for a long time. A scientist, a philosopher, and the president of a poultry farming association recently gave the same answer: the egg came first.

According to the report, Professor John Brookfield, an expert in genetics on species evolution at the University of Nottingham in the United Kingdom, believes that for him, the answer could not be clearer. He said that after an individual animal is born, the genetic material in its body does not change. Modern biomolecular theories believe that it is the genetic mutation of the genetic material in the egg that makes it possible for the chicken species to appear.

Brookfield further explains that the first chicken is an embryo contained in the egg, and that the genes of that embryo are the same as those of the chicken that was born; That is, the first member of the species belonging to the chicken must be an egg containing the genetic material of the chicken.

David Papineau, a philosopher at King's College London, UK, proved Brookfield's point of view from a philosophical point of view. He said, "Plant melons and get melons, and sow beans and get beans."

It is said that the egg was laid by a kangaroo, but it turned out that the egg hatched an ostrich, then the egg must have been laid by an ostrich, not a kangaroo. By the same token, the first chicken could not have hatched from an egg laid by another species of animal.

According to the report, Charles Borosh, president of a British poultry breeding association, said: "Before the first chicken is born, there must be eggs. Of course, those eggs may not look the same as the eggs now.

In fact, the question is very simple, there must be an egg first, because the first egg is definitely not laid by a chicken, and the amphibian will lay an egg. Given that the first chicken can only come out of one egg, and this egg is always laid by an oviposition animal that cannot be called a chicken, you can go back several generations to hundreds of generations until the first amphibian that can lay eggs, so of course there is the egg first.

The above conclusions are based on your question, that is, chickens appear directly.

Science doesn't know things, and we ordinary people don't know either, so don't waste time on fruitless problems! Because human time is precious.

Because of the genetic change, a winged animal lays several eggs (called eggs), mates, and reproduces!

The chicken is an animal that must have evolved from such and such an animal.

Chickens came first, and according to biological evolution, chickens are more likely to appear first than eggs.

It's a question of evolution. It was supposed to be some kind of large bird that used to live near human habitats, and people began to hunt it and raise it for food. Due to the long-term artificial breeding.

degrades its ability to fly and reduces its sensitivity. So its offspring are worse from generation to generation, and until now they can only be slaughtered. It's like wild boars and domestic pigs.

Intelligence questions, IQ test. How many squares are there?

16 + 9 + 4 + 5 + 5 + 1 = 40 (pcs).

Test everyone: This is a math problem that can be used to test whether a person has business acumen or not. Master Wang is selling fish, a pound of fish at a price of 45 yuan, now a big sale at a loss, the customer bought a kilogram for 35 yuan, gave Master Wang 100 yuan fake money, Master Wang has no change, so he asked his neighbor Liang Blind for 100 yuan.

Afterwards, the neighbor found out that the money was fake in the process of depositing money, and it was confiscated by the bank, and Master Wang lost 100 yuan to the neighbor, how much did Master Wang lose in total?

Note: The difference between catties and kilograms.

A total loss of 100 + (45 2-35) = 100 + 55 = 155 yuan.

Question 4, the right-angled side of an isosceles right-angled triangle is the waist, so the length of the right-angled side is 20 2=10, and the area is.

10 10 2 = 50 (square centimeters).

5 questions, 2 = 10 5, 250m = 1 4km, the latter question can only be guessed because you can't see the back, it may be 3 divided by 3 = 5 5 = 21 21, or.

3 divided by 1 = 15 5 = 21 7, or.

3 divided by 15 = 1 5 = 21 105 ,......

6 questions, turned an odd number of times, with the mouth of the cup facing up.

7 questions, the perimeter is.

3+1) 2 2 = 16 cm, the area is 2 2 3 = 12 square centimeters.

Divide by, so.

It can be divided into 6 segments.

Because it is an isosceles right-angled triangle, the two right-angled sides are equal.

Because the sum is 20, 10 for each of them, the area is 10*10*1 2=50

(1) The Communist Party of China represents not only the interests of the working class, but also the interests of the entire Chinese nation, (2) The countryside surrounds the cities and the Jinggangshan Revolutionary Base Area, and (3) It has established a correct strategy, formulated the party's general line and basic program for the period of the new democratic revolution, solved the party's basic problems such as the united front, armed struggle, and party building in the Chinese revolution, formed a complete theory of the new democratic revolution, and realized the first historical leap in integrating the basic tenets of Marxism with China's reality. The foundation was laid for the final victory.

I don't know if the above answer is right or not, but I have done it seriously, but I have graduated from junior high school for 2 years, and the correct answer is almost forgotten, after all, the history I am studying now, even if it is somewhat similar to junior high school, but the answer is different.

I can't see it clearly, can you send another one?
