The assembly of fish gene maps primarily during the last two decades has resulted in important new insights into the evolution of vertebrate chromosomes and karyotypes. While mammalian karyotypes apparently have evolved rapidly to generate haploid chromosome numbers from 40, teleost fish karyotypes ...

The fossil discovery suggested that haramiyidans and some other vertebrate groups existed globally during the Jurassic-Cretaceous transition, meaning the corridors for migration via Pangean landmasses remained intact into the Early Cretaceous. Most of the Jurassic and Cretaceous fossils of haramiyidans ...
“This process of apparent conflict betweenDNAand fossils, and eventual reconciliation through new discoveries is a great example of scientific progress, and how our knowledge of vertebrate evolution is itself continually evolving,” Field said. ...

The distribution of the Mediterranean Transphlebotomus species shows a marked zoogeographical dichotomy in the sense that Phlebotomus mascittii has a wide range in Europe, and the other species are restricted to the East Mediterranean region. The study aimed to investigate how the Neogene to late...
