1:50-2:04 Finally, dolphins are fish.

[@fishlaw1]

Awesome Lecture. Thanks for sharing ! ! !

[@nathanhopkins7976]

Really nice overview of early fish evolution/cladistics. Keep it up!

[@BeaChapman]

Great video!

[@ThorkilKowalski]

This is great! It seems that there is a gap around 18:20 though. Are we missing a part of the lecture there?

[@mementovivere2]

Yeah it would be great to have that as well!

[@GringoActual]

Are there more videos in this fish series? I am particularly interested in fish and I've thoroughly enjoyed these two videos.

[@thomasevans3387]

Unfortunately my new job and normal life circumstances have kept me far too busy to make any new videos for KZbin. For right now, and the foreseeable future sadly, only these videos are up. If you are finding these interesting I would strongly recommend you look into getting a good Ichthyology textbook as you will find this information and more.

You all prolly dont give a damn but does any of you know of a tool to get back into an Instagram account?? I was stupid lost the login password. I appreciate any tips you can give me

@Bridger Zev instablaster ;)

[@bridgerzev8745]

@Isaac Gael I really appreciate your reply. I got to the site through google and Im in the hacking process now. Looks like it's gonna take quite some time so I will reply here later with my results.

[@FoxDren]

much rather have a book on this than some principica mathematica. perhaps someone can ask the royal society

[@mementovivere2]

Hey Thomas this is a great lecture and you are an amazing teacher. Thank you for recording this.

[@Guitcad1]

Is there a higher quality version of your geological time chart available anywhere? Some of it, like the magnetic polarity columns, are too poorly resolved here to be legible.

[@illuser_3318]

Thanks bro

Hi Thomas! I am going to be writing a scientific paper in high school about the evolution of fish. I have just started my research, and I have learnt a lot from this Video alone. I have been looking for books for information for my papers. What books could you recommend for an overview about this topic? As I said, i've just started researching, so my knowledge is not huge at all. Some books I considered would be "Discovering fossil Fishes", "The Rise of fishes" and "The Diversity of fishes". If you have read these books are they up to date, and do they provide reliable information? Kind Regards

[@thomasevans3387]

Hi Farkas, Thank you for the compliment! It depends on how much you want to get into this (upper level high school courses could definitely try a college textbook, lower level courses you probably want more general population literature because you don't have the experience yet with the material). You have a good list of books there, and there will be more than enough information for you to write a paper. The textbook I learned from and still often refer to is: "The Diversity of Fishes: Biology, Evolution, and Ecology". While it is now a bit dated in regards to the evolution of fishes, it is still very good, and it has a good overview of the topic. You can buy this, but you should be able to find it at a large library (especially a college library) or with a inter-library loan. That book is a college level, but might be a good fit for your paper. If you find something interesting you can always go to google scholar and type in the keywords. I would limit your search to 2000 onward since there is tons to read. This book (Evolution and Development of Fishes) just came out, and looks promising, but it is probably impossible to find. If you do find a copy I would take a look at it's first chapter. You might also contact the lead author directly and ask for a copy of the first chapter with a note explaining why. Often they are very excited to hear from people and send a copy of a chapter. For a more general book I would always recommend Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body, it is a great book and while it won't give you the coverage you exactly want I suspect, it does get the excitement and interest up. Let me know if that helps.

@@thomasevans3387 I don't really know yet how in dept i will (have to) go, but it is not something you can finish in 2 weeks. We are going to spend the next 1 ½ Years writing it, and it will consist of roughly 20-30 Microsoft Word Pages, which would be around 40-60 Thousand Characters. Your Inner Fish I have definitely been keeping an eye on,and I am without a question going to read it, but as you said, right now I need literature that really helps me cover the topic. And about the Diversity of Fishes: Were you reffering to the older version or the updated one?

[@thomasevans3387]

@@farkaselliott0161 The updated version is still from 2009, 10 years old now, and there have been a couple of pretty big discoveries since then. However, I don't know if the authors are working on an updated copy. Glad to hear that you are going to have some time to work on this, there is a ton to learn and certainly plenty to explore on this topic. I think you will find we have more questions than answers.

[@farkaselliott0161]

@@thomasevans3387 I am most definitely excited about the journey! My only concern now, is that we have to hand in kind of a brief explanation of our topic, and a rough structure of how we are going to segment the chapters of our paper. I am not quiet sure what I will be able to find on thr topic. Am I on the safe side on finding enough information about anatomical/ecological and ethologic adaptations, and about why certain evolutionary stages where necessary for survival? I may sound a bit broad, but as I said, I only have a broad imagination of what the topic really consists of.

[@centropygepotteri]

​@@farkaselliott0161how'd you go with the paper in the end?

[@potohbab8056]

@thomas Evans what is the most interesting fact about fishes?

[@thomasevans3387]

Hmmmmm, one random interesting fact? Hard to do since there are so many. I think the one that gets people thinking most though is that humans are classified as lobe-finned fish.

Hi sir Do you have PDF copy

"No intermediate fossils between jawed and jawless forms have been found - early fossils of jawed fishes had jaws, teeth, scales and spines. The origins of jaws and other structures that characterized the early gnathostomes are lost in the fossil record, belonging to some group about which we known nothing. " (Helfman, G.S., B.B. Collette and D.E. Facey. 1997. The Diversity of Fishes. Blackwell Science, MA. 528pp.; p. 157) “Origin of the vertebrates is obscure-there is no fossil record preceding the occurrence of fishes in the late Ordovician time.” Arthur N. Strahler, Science and Earth History: The Evolution/Creation Controversy (Buffalo, New York: Prometheus Books, 1987), p. 316. "All the larger groups of animals, e.g. fishes, amphibians, reptiles, mammals seem to have appeared suddenly on the earth, spreading themselves, so to speak, in an explosive manner in their various shapes and forms. Nowhere is one able to observe or prove the transition of one species into another, variation only being possible within the species themselves" - Evolutionist, Max Westenhofer as quoted in Dewar's More Difficulties, p. 94 "The common ancestor of the bony-fish groups is unknown" - (Alfred Sherwood Romer, Vertebrate Paleontology, 3rd ed.[Chicago: University of Chicago Press, 1966], 53). As our present information stands, however, the gap remains unbridged, and the best place to start the evolution of the vertebrates is in the imagination. Homer W. Smith, From Fish to Philosopher (Boston: Little, Brown, and Co., 1953), p. 26.

I think you need to re-listen to the bit starting at around 31:00. Look, there are many unanswered questions out there - there are many, many things we do not know about our cosmos, or what it is, or where it came from. But we do know that it was not created in seven rotations of this planet by the God of the bronze age Israelites. Sorry buddy. It just didn't happen like that. If you believe that the Earth upon which we live revolves around the sun, then you must necessarily believe that you and the rest of us living things came into being via evolution by natural selection. Because science is not a set of beliefs, it's a *methodology* used to answer questions. That same rigorous methodology that has proven beyond any reasonable doubt that heliocentrism is fact - despite no human being ever possibly being able to directly observe the earth moving 'round the sun - also proves beyond any reasonable doubt that all life on earth shares a common ancestor. I'm afraid you don't get to cherry pick - if you believe the former, then you're obliged to believe the latter because they're conclusions that have been arrived at the same way.

[@Guitcad1]

What is the point of spewing quotes that are over fifty years old? You _do_ realize science acquires knowledge over time, right? You are on a buildup to an argument from ignorance. You're one of those people who every time one missing link is found claims that now there are TWO missing links on either side of it. And _seriously?_ "Nowhere is one able to observe or prove the transition of one species into another"? Horses: Eohippus, Orohippus, Epihippus, Mesohippus, Miohippus, Kalobatippus, Parahippus, Merychippus, Hipparion, Pliohippus, Ninohippus, Plesippus, and ending with Equus, modern horses. These come from different layers of the fossil record. They existed at different times, and each is clearly closely related to the ones on either side. Same goes for whales and numerous other groups.

[@marconatrix]

What a terrible long-winded rambling delivery. Sounds more like an ad hoc conversation with a hitch-hiker than a prepared professional lecture.

[@marconatrix]

What a terrible notion! No, just my honest criticism. If it worked for you, all well and good.

[@knyghtryder3599]

hahahaha you do better,,,, hahaha where are your genius lectures??? where are your rousing speeches and model face shots , the eternal internet critics are out people , judgment is everywhere
