Because of the result of genetic mutations, it may also be to better survive in a harsh environment.
-
This is to better adapt to the living environment.
-
A product of evolution to adapt to the survival of nature.
-
Survival of the fittest, survival of the fittest, in order to adapt to the environment has to be done.
-
The fittest survive, and the unfit are eliminated. Most insects have six limbs and are all designed to adapt to their environment.
-
Natural selection, the cause of the evolution of species.
-
In order to better adapt to the environment in which it lives.
-
This is the product of nature's evolution by selection.

The basic characteristics of insects can be summarized as follows: "The body has three heads, a thorax, and an abdomen, two pairs of wings and six legs; 1 pair of antennae cephalic, bones wrapped around the outside of the body; The form of life is varied, and it is spread all over the world.
Arthropod phylum - Insecta - Animals under this definition Its common characteristics are: hexapod, no bones, the body is supported by a hard shell on the body surface, divided into three growth stages of egg, larva and adult, and the body is multi-segmented.
The body of spiders and scorpions is divided into two parts, cephalothorax and abdomen, and they also have 8 legs, so they are not insects. Centipedes and horses have more legs, and there are 1 2 pairs of legs on almost every link (body segment), and of course they are not insects.
Therefore, the insect must be 6 legs.
-
It can't be said that insects are all six-legged, just the ones we commonly see. After adulthood. Insects that will have wings, and most of them are six-legged.
Their larvae are not six-legged either, but many-legged. There are some insects that don't grow wings when they are adults, and they all have a lot of legs. Common ones are horses, grasshoppers, centipedes.
There are also mountain worms.
-
The adult of the insect is six-legged. It's hard to say about the larvae. Some insects have appendages that cannot be considered feet.
The definition of an insect is three pairs of legs and two pairs of wings. But some insects have degraded wings. Like flies, the second pair of wings degenerates into a balance bar.
Some insects do not have wings at all, such as the early insects, silverfish, which belong to the order Ptera. In the common phylum Arthropods, there are insects with 3 pairs of legs. Arachnids (spiders, tide insects), 4 pairs of legs.
Myriapoda, n-to-pod (road, centipede).
-
There are many kinds of them. Only 1 part is 6 legs.
-
The one who says that spiders are insects is a sense of existence? Spiders are arachnids and not insects.
-
The adult insect has six legs, but in the evolution of its growth and development, there are 3 pairs of appendages that are specialized into feet, and it also has other appendages, such as the lower jaw whiskers on the head and the grip on the abdomen.
-
Not all insects have six legs!!
-
Yes, the class of insects was formerly known as "hexapod", which means six-legged. There are many kinds of insects with different morphologies, and in terms of scientific classification, insects are included in the phylum Arthropods, Hexapod, which have the common characteristics of arthropods.
Insecta is not only the largest class in the phylum Arthropods, but also the largest in the animal kingdom. Not only are there many species of insects, but the number of individuals of the same species is also staggering. The distribution of insects is so wide that no other class of animals can compare with it, and it is almost all over the earth.
-
Yes, insects belong to the category of arthropods and are characterized by two pairs of wings and 3 pairs of legs divided into cephalic, thoracic, and ventral.
Caterpillars look at adults.
Extra points, oh urgent.
-
Generally six-legged (definition).
Either arthropods or myriapods.
-
Yes, it's not six-legged arthropods.
No, we also have gas in our bodies, but the space is too small for us to know much.
The so-called culture is a comprehensive cultivation that combines knowledge, thinking and experience, and is a person's inner quality. Receiving education is an important way to have cultural accomplishment, but having more educational experience does not necessarily mean that you can really have a higher cultural accomplishment. There is no necessary causal relationship between the two. >>>More
