Brood care in a 100-million-year-old scale insect
Behavior of extinct organisms can be inferred only indirectly, but occasionally rare fossils document particular behaviors directly. Brood care, a remarkable behavior promoting the survival of the next generation, has evolved independently numerous times among animals including insects. However, fossil evidence of such a complex behavior is exceptionally scarce. Here, we report an ensign scale ...
متن کاملFibres and cellular structures preserved in 75-million–year-old dinosaur specimens
Exceptionally preserved organic remains are known throughout the vertebrate fossil record, and recently, evidence has emerged that such soft tissue might contain original components. We examined samples from eight Cretaceous dinosaur bones using nano-analytical techniques; the bones are not exceptionally preserved and show no external indication of soft tissue. In one sample, we observe structu...
متن کاملSound strategies: the 65-million-year-old battle between bats and insects.
The intimate details regarding the coevolution of bats and moths have been elucidated over the past 50 years. The bat-moth story began with the evolution of bat sonar, an exquisite ultrasonic system for tracking prey through the night sky. Moths countered with ears tuned to the high frequencies of bat echolocation and with evasive action through directed turns, loops, spirals, drops, and power ...
متن کاملNon-sexual abdominal appendages in adult insects challenge a 300 million year old bauplan
pterygotes (e.g., the tracheobranchial appendages in mayfly nymphs, the tracheal gills of larval gyrinid beetles and those of neuropterids such as Corydalis) usually serve functions other than sexual, i.e., they are either respiratory or locomotory. As a first step to elucidate what drove the evolution of non-sexual abdominal appendages in Bennini, we investigated topology and anatomy of the ap...
متن کاملA Thirty Million Year-Old Inherited Heteroplasmy
Due to essentially maternal inheritance and a bottleneck effect during early oogenesis, newly arising mitochondrial DNA (mtDNA) mutations segregate rapidly in metazoan female germlines. Consequently, heteroplasmy (i.e. the mixture of mtDNA genotypes within an organism) is generally resolved to homoplasmy within a few generations. Here, we report an exceptional transpecific heteroplasmy (predict...
