How Do You Know Someone Is Dead?

i'm in for it um the actual news i was going to cover also slightly interesting my old lab head up a project called bat 1k and essentially they recon or they were doing an analysis of um the bat genome and where all bats have evolved from because one in five mammalian species is a bat That's just if you're going by pure number of species, not number of animals.

103 bat species they've sequenced the genome of so far.

42 are completely new.

They've covered all 21 bat families and found that... previous studies suggested africa asia or north america because that's where early bat fossils were recorded and that's where they're so fragmented but this new analysis suggests that bats and therefore powered flight in mammals probably originated in europe So yeah, more to come as they look at more genomes.

And of course, bats are one of the only species to use laryngeal echolocation.

And there was a longstanding question over whether that evolved once in bats or appeared and then disappeared in some lineages like vampire bats don't echolocate or did it appear in several lineages spontaneously and they suggest that laryngeal echolocation was present before modern bats diversified into their major groups and that kind of makes sense right we think about echolocating dolphins did they develop that separately no it was probably just one ancestor had that um so yeah but they're trying to reconstruct the entire evolutionary space one sequence that produced bats and this is the first big paper so they got the cover of nature this week and um yeah i i've left that world behind so good luck to them and bats in general but yes death and if at some point i randomly start speaking about music it's because i remembered what the fuck i was gonna say but yes fact fact death facts i don't have any
