An International team revealed a comprehensive insect family tree. The researchers formed this tree with the help of the genetic data, which is almost half a billion years old.

The panel in detail explained the relationship of insects with one another. The team examined approximately 1,478 genes from 144 different species which covers all the main insects groups. The group specially designed this tree in order to answer several questions related to the biggest animal groups.

Bernard Misof, the main author of this report stated that around two third of animal species are insects. These insects play a vital role in the Earth’s ecosystem.

The study revealed that the first insect emerged nearly 480 million years ago on the planet Earth. The researchers guess this time period with the help of genetic data.

Karl Kjer, co-author of this study informed that 480 million years ago Earth was pretty similar to the Red planet. The entire Earth was packed with only sand and rocks without any sign of life on land.

Moreover, he notified both animal and plants appeared at the same time on the planet Earth. They helped each other to some extent in their growth.

The report unveiled that the evolution of plants is associated with the emergence of wide range of flying insects such as bees, flies, beetles, moths and butterflies.
