WEBVTT 99:59:59.999 --> 99:59:59.999 I've been spending my summers 99:59:59.999 --> 99:59:59.999 in the Marine Biological Laboratory in Woods Hole, Massachusetts 99:59:59.999 --> 99:59:59.999 And there, what I've been doing is essentially renting a boat. 99:59:59.999 --> 99:59:59.999 What I would like to ask you to do 99:59:59.999 --> 99:59:59.999 is to come on a boat ride with me tonight. 99:59:59.999 --> 99:59:59.999 So, we ride off from Eel Pond into the Vineyard South, 99:59:59.999 --> 99:59:59.999 right off the coast of Martha's Vineyard, 99:59:59.999 --> 99:59:59.999 equipped with a drone to identify potential spots 99:59:59.999 --> 99:59:59.999 from which to peer into the Atlantic. 99:59:59.999 --> 99:59:59.999 Earlier I was going to say 99:59:59.999 --> 99:59:59.999 into the depths of the Atlantic, 99:59:59.999 --> 99:59:59.999 but we don't have to go too deep to reach the unknown. 99:59:59.999 --> 99:59:59.999 Here, barely two miles away, 99:59:59.999 --> 99:59:59.999 from what is arguably the greatest marine biology lab in the world, 99:59:59.999 --> 99:59:59.999 we lower a simple plankton net into the water 99:59:59.999 --> 99:59:59.999 and bring up into the surface things that humanity rarely pays attention to 99:59:59.999 --> 99:59:59.999 and oftentimes, have never seen before. 99:59:59.999 --> 99:59:59.999 Here is one of the organisms that we caught in our net, 99:59:59.999 --> 99:59:59.999 this is a jellyfish. 99:59:59.999 --> 99:59:59.999 But look closely, living inside this animal is another organism 99:59:59.999 --> 99:59:59.999 that is very likely entirely new to science. 99:59:59.999 --> 99:59:59.999 A complete new species. 99:59:59.999 --> 99:59:59.999 Or how about this other transparent beauty? 99:59:59.999 --> 99:59:59.999 With a beating heart, asexually growing, 99:59:59.999 --> 99:59:59.999 on top of its head, 99:59:59.999 --> 99:59:59.999 progeny that will move on to reproduce sexually. 99:59:59.999 --> 99:59:59.999 Now let me say that again, 99:59:59.999 --> 99:59:59.999 this animal is growing asexually, 99:59:59.999 --> 99:59:59.999 on top of its head, 99:59:59.999 --> 99:59:59.999 progeny that is going to reproduce sexually in the next generation. 99:59:59.999 --> 99:59:59.999 A weird jellyfish, not quite, 99:59:59.999 --> 99:59:59.999 this is an ascidian, this is a group of animals 99:59:59.999 --> 99:59:59.999 that now we know we share extensive genomic ancestry with, 99:59:59.999 --> 99:59:59.999 and it is perhaps the closest invertebrate species to our own.
