Bush of life: comb jellies

Where do they fit in the bush of life. Did they develop muscles and a nervous system before everyone else? What is wrong with accepting convergence?-http://www.sciencenews.org/view/feature/id/350120/description/Evolutionary_enigmas

Bush of life: using gene trees

It doesn't work well, using genes to design evolutionary tree relationships:-"For some researchers, the idea of selectively excluding data from analysis could take some getting used to. "For many years, the biggest problem for people trying to understand relationships between organisms was getting enough data," said Jeffrey Townsend, an evolutionary biologist at Yale University, who was not involved in the study. "The community has always been taught to get the data, so it's reasonable that's how they thought about the problem."
 
While evolutionary biologists have been grappling with these issues for years, the new study is the largest-scale effort to date to explore the level of conflict among individual genes. "People will have two reactions: There is a lot more conflict than I thought, and we need to do a better job of analyzing it," said Donoghue, who is interested in applying the new method in his own work. However, he also points out that it's difficult to confirm the accuracy of the new approach. Even though the revised tree matched one built using alternative genetic information, the latter may harbor its own inaccuracies. "I am not so sure we know what the true relationships are," he said. "If we aren't sure what the truth is, we can't tell if we have the right tree.""-https://www.simonsfoundation.org/features/science-news/a-new-approach-to-building-the-tree-of-life/0/

Another paper noting that genomic study of evolution does not create a tree of life:-:The irrefutable demonstration by phylogenomics that
different genes in general have distinct evolutionary histories
made obsolete the belief that a phylogenetic tree
of a single universal gene such as rRNA or of several
universal genes could represent the "true" TOL."-http://www.biologydirect.com/content/pdf/1745-6150-6-32.pdf-And then we have Dawkins who doesn't believe the scientific facts:-https://www.youtube.com/watch?v=TjxZ6MrBl9E
