The Genome 10K project wants to sequence the genomes of thousands of vertebrates, including ones that are endangered, Digital Trends reports.
Peter Konstantinidis, curator of vertebrates for the Oregon State University Department of fisheries and Wildlife, stands among cabinets filled with bird specimens in the basement of Nash Hall on Monday.
The Kabobo Massif is one of the most biodiverse sites in Africa. To date 558 terrestrial vertebrates and 1,410 plant species have been documented.
But insects, Berenbaum said, don't get nearly as much love as humans' fellow vertebrates, especially mammals. Comparatively few insects earn the "at risk" distinction often given to mammals.
One vertebrate character it supposedly had was a notochord, a flexible rod of cartilage running down its back. This is present in the embryos of animals from halibuts to humans, and by maturity it is mostly replaced by a series of bones called vertebrae.
"It is also unexpected because such conditions of fossilization reveal an impressive animal biodiversity that includes sponges, brachiopods, mollusks, arthropods, echinoderms and vertebrates, all coexisting in the very same ecosystem." The team notes ...

Illustrative of the controversy caused is the fact that two papers published within six months of each other, disagree even at the fundamental level of whether it is a vertebrate or an invertebrate. The pro-vertebrate camp, which in this incarnation is ...
Considering how different they look from the outside, it might be surprising that all vertebrates - animals with a backbone - share the same, conserved set of organs.
The Kabobo Massif is one of the most biodiverse sites in Africa. To date 558 terrestrial vertebrates and 1,410 plant species have been documented.
"All the major textbooks covering the topic of the evolution of the vertebrates will now need to be re-written if this suggestion survives academic scrutiny and becomes accepted more widely," said Cambridge Professor David Norman, who supervised the ...
In the same book, Coyne presents a grand example of a testable prediction to support evolution: There were no terrestrial vertebrates until 390 million years ago, but clearly, they existed around 360 million years ago. Evolutionary theory, then, would ...
