First of all, this is a false proposition, there is no problem of eggs or chickens first, want to know how chickens come from, this to understand the history of nature and even the earth, here is not a detailed introduction, the history of the earth can be told for 3 days and 3 nights.
Nature is the first to be formed by microorganisms, due to changes in the earth's environment, different nutrients absorbed by organisms, microorganisms will gradually form algae plants, the emergence of algae plants, the underwater environment will be completely changed, at this time breeding a lot of small underwater animals, at this time, the animal species will appear on the earth, the earth environment will continue to change, a variety of animals extend and evolve, and underwater animals slowly transform amphibians, land animals and flying animals, all things are this theory, including humans, It all comes with the slow evolution of the environment.
Evolutionary evolution of animals: from single-celled animals to multicellular general direction: single cells such as (grasshoppers) → coelenterates (such as corals) → sponges→ flat animals→ linear animals (pork tapeworms) → echinoderms (starfish) → chordates (Wenchang fish) → vertebrates (proto-mouth → fish→ amphibians→ reptiles→ mammals → humans) but there seems to be a saying that humans and reptiles evolved from two branches, but this is a long-term earth environment derived. Not overnight
As for the chicken breed, first of all, there are wings and claws, as well as a pointed mouth, it can be imagined that it is transformed from some kind of bird, and its body shape should be more eagle-like, but there is no strong image of eagles, it should be in ancient times, there are many birds and animals, there are maggots and other foods on land, and some animals gradually grow forage on land for a long time, so it slowly transforms into a chicken breed.
All things are this theory, and all things come from this way, so the so-called chickens and eggs are not right, they are all slowly evolved. I don't know how many tens of thousands of years of evolutionary period there is in the middle.
Similarly, the earth's environment is still slowly changing, and many animal breeds are slowly emerging. Don't be surprised!!
Just after the end of 2013, the Journal of Mammalology was published in
A newly discovered species of tapir in the Amazon is named Tapirus kabomani. This is the fifth known tapir after the Tapirus indicus (not Cherging's), the South American tapir (Tapirus terrestris), the tapir (Tapirus pinchaque), and the Tapirus terrestris, and is a newly recorded Perissodactyla animal in the past hundred years
In the rainforests of Brazil, scientists have discovered a relict insect, the nymph scorpion frog Astromerope brasiliensis, the third living nymph scorpion (Meropeidae).
