I said I was going to do it, and I’m going to. I’ll start shortly.
One thing I should mention is that I’m going to stop after one hour. I’ve seen some of these videos go on for hour after hour, and you can only do that if you’re talking about substanceless drama. Or creationism…those twits are obstinate and persistent. I will draw the line at 3:00 Central, which means I most probably not talk about all of these things. That’s OK, I can continue on a different day.
Can new species evolve from cancers?
How Many Genes Do Cells Need? Maybe Almost All of Them
Light-regulated collective contractility in a multicellular choanoflagellate
The Early Ediacaran Caveasphaera Foreshadows the Evolutionary Origin of Animal-like Embryology
That last one is a long, difficult paper anyway.
Also, if people ask me questions about other things, we can go off on a tangent. That’s OK, too, but I’m still going to insist on cutting off at an hour.
I’m here PZ.
I guess we’re not live?
@nomdeplume:
Did you get the time zone mixed up? PZ is in Minnesota. 2pm there is noon on the west coast of the US & Canada. Given your time stamps showing up as 4:28/9 I’m wondering if maybe you’re there?
Hi Crip, no I’m in eastern Australia, and got thoroughly confused checking which American time zone PZ was in. Never mind, have started watching the recorded youtube video.
Sorry if you got to this later on in the video, but I was wondering regarding cancers creating new species, if something like that could happen with canine transmissible venereal tumour. It’s got it’s own genome separate from its hosts. What would need to happen for it to be classified it’s own species of parasite?
PZ – I thought with the choanaflagellates you were going to talk about the apparent ability of a single individual, of at least one species to learn about a threat in its environment, try to deal with it by a couple of mechanisms, and then when that doesn’t work, moving away totally. It implies that there is some cellular mechanism in this species that allows a kind of memory. Interesting. Would love to hear your take on it.
