Question

The first animals to fly were
A. Mammals
B. Lizards
C. Birds
D. Insects

Answer 1

Hint: The evolution of the main group of vertebrates has always been associated with functional changes. The first animals to fly were believed to originate from the Ordovician on Earth about 480 million years ago, around the same time that land plants appeared. They can evolve from a group of crustaceans.

Complete answer: Let’s study about each option one by one for answering the question.
Mammals are warm-blooded vertebrates. Young mammals are born live (with the exception of monotremes laying eggs) and are fed by the mother with early childhood milk secreted by the mammary glands. It is characterized by a separate opening of the anus and genitourinary system (except for monotremes).
Birds are a highly specialized group of vertebrates that evolved from reptiles in the Mesozoic. Actual documentary records of the stages showing how reptiles turned into birds are extremely rare due to the lack of bird fossils. Two fossil specimens of Archaeopteryx found from the upper Jurassic valley strongly support this claim. The evolution of the main group of vertebrates has always been associated with functional changes. The development of birds is associated with changes in life from land to air.
Lizards group of mackerel reptiles found on all continents except Antarctica and most of the oceanic island chain. This group is paraphyletic because it does not include snakes and amphisbaenians. Some lizards are more closely related to these two excluded groups than are other lizards. Lizards vary in size from chameleons and geckos.
The insect class is believed to have originated from the Ordovician on Earth about 480 million years ago, around the same time that land plants appeared. Insects can evolve from a group of crustaceans. The first insects were associated with land, but a number of flying insects evolved in the Devonian era about 400 million years ago, the first animals to do so.
The origin of insect flight remains unclear, as the earliest winged insects known today appear to be skilled pilots. Some extinct insects (for example, Palaeodictyoptera) have an additional pair of wings attached to the first segment of the thorax for a total of three pairs. The wings themselves are sometimes referred to as heavily modified gills (trachea). By comparing a pair of well-developed gill blades on the Mayad Naiden and a pair of reduced adult hind wings, it is not difficult to imagine that Tergaliae's gills and insect wings had a common origin, as recent research has shown Specifically, genetic studies on the mother have shown that the gills and wings of insects can come from the legs of the insects.
So, the correct answer is “Option D”.

Note: In other winged insects, flight muscles stick to the chest, causing them to flap and flap. Some of these insects (biplanes and some beetles) achieve very high wing-flapping frequencies through the development of an "asynchronous" nervous system in which the chest vibrates faster than the speed of nerve impulses.
Some of the very small insects do not use stationary aerodynamics, but use a Wise Fogg mechanism and trap, which creates a large lift at the expense of wing wear. Many insects can hang, maintain their height, and control their position. Some insects, such as Moths have front wings on their hind legs so they can work together.
