The oldest fossil resin dates to the Triassic, though most dates to the Cenozoic. The excretion of the resin by certain plants is thought to be an evolutionary adaptation for protection from insects and to seal wounds. Fossil resin often contains other fossils called inclusions that were captured by the sticky resin.

Can we know the color of a 200-million-year-old insect? Some people will say we can only imagine its actual color. But no! Scientists from China, Germany and the UK have new evidence to reveal the.

The study of insect evolution is hampered by a gigantic gap in the fossil record. Although fossils of early nonflying insects have been found in sediments dating from the Devonian period nearly 400 million years ago, no insect fossils have turned up from the following 75-million-year period.

Plants with flowers are far more likely to become fertilized, thanks to the help of insects or the wind. as the sediments, where the fossil is preserved, and the morphology of the leaves suggest.

Coleoptera wings seem to have developed from predecessors of symmetric type, but their morphology is strongly influenced by the need to fold up at rest. Diptera provide an excellent illustration of the evolution of asymmetric, high‐performance wings from the symmetric, ‘mecopteran’ type.
