Confirmed that modern placental mammals originated after the "Dinosaur Mass Extinction"
Science and Technology Daily, Beijing, December 27 (intern reporter Zhang Jiaxin) According to a new study published in the latest issue of "Nature", British scientists have provided the most detailed timeline of mammalian evolution to date, confirming modern placental mammals The group originated after the "Dinosaur Mass Extinction"
This research describes a new and fast calculation method that can obtain an accurate evolutionary tree, which is the so-called "timeline
Placental mammals are the most diverse group of existing mammals, including primates, rodents, cetaceans, carnivores, pterodactyls (bats), and humans
The lead author of this paper, Dr.
Inferring the evolutionary timetable is a basic research goal of biology
In this study, the researchers developed a new and fast Bayesian method to analyze a large number of genome sequences, while also considering the uncertainty in the data
The method developed in this research can be used to deal with other controversial evolutionary timelines that require analysis of large data sets
