What key evolutionary event is suggested to have been established during the Jurassic period based on 160-million-year-old forms?
Answer
The foundational body plan for many aquatic Hemiptera
Comparing the morphology of modern aquatic bug groups, such as the Belostomatidae, with fossils dating back approximately 160 million years provides strong evidence regarding the establishment of fundamental structures. The comparison reveals that the essential, foundational body plan necessary for success in the aquatic realm for many members of the Hemiptera order was already firmly established and recognizable during the Jurassic period.
