What are the most important evolutionary innovations?

Apppear's evolutionary innovations were relatively few and far among the first three about billions of years of life on Earth. The main evolutionary innovations during this time were the development of oxyphotosynthetic bacteria and complex cells (eukaryotes). Although life itself originated at least 3.7 billion years ago, it was only 600 million years ago that the first evidence of multicellular life appeared.

Discounting of protozoans (unicellular) evolutionary innovations that many scientists would claim to be the most important of all for technical reasons, there are a number of evolutionary innovations whose usefulness is obvious to anyone. The five evolutionary innovations that seem most important are the development of the third layer of germ germ germ germination, which allows a body cavity, also called coeloma; the predation that set up an evolutionary change in the race; the eyes that have become so successful after their initial development that most macroscopic animals are inherent; colonization of the earth with plants and animals; and the development of the real flight that occurredFour times independently and opened a huge new niche for colonization of animals.

The development of the third layer of germ germs, ie triploblastic animals, occurred between 600 and 580 million years. The earliest known triploblastic fossil is Vernanimalcula Guizhouena , a small spherical animal only 0.1 mm in diameter. It was found that this animal has two body cavities separating its intestines from the wall of the body. This physiological arrangement helps to pour the internal authorities in separating structural dependencies between them, allowing them to evolve independently. This is an invaluable evolutionary innovation.

The development of predation and eyes probably appeared close to each other and both very early. Given what we know, it is reasonable to assume that Both has become about the same time, at the Cambrian-Precambrian border about 542 million years ago. All eyes are monophyletic, which means that they are shakingThey lie to the common predecessor who developed during this period. This is, unlike an earlier view that claimed that the eyes had developed independently on several occasions. At about the same time, the first organisms with hard shells appeared, and these shells can be seen a small holding, which is a sign of predators. Predations may have evolved earlier because there is a cursory evidence of the predation from the Ediacaran period, 10-20 million years before the Cambrian-Prekambrian.

The last two evolutionary innovations with great importance are the transition to landing and moving to the air. Moving to the ground is the most important of these two, which occurs between about 460 and 430 million years, during the Ordovice and Silurian periods. Around this time, green algae has evolved into earthly plants, which were folldldldldli for tens of millions later by simple arthropods, including ancestors of modern spiders and harvesters. Millipede's earliest earthly fossil. Much later, about 350 miles beforeIONE years, during the carbon period, insects developed for years, using a huge new niche. The flight would develop three times: pterosaurs, birds and bats.
