Thank you very much! Really appreciate your videos, they're very helpful in understanding our evolution! Plus, they help understand why animals are named difficult names.
Tremendous Lectures! I like your lecture style and your videos are very informative, you really have the best lectures available on-line, but you really should focus a bit more on phylogenetic data, some students might wrongfully think that your three of features, or whatever it is, is representative of the evolutionary relationships between different phyla.
Very nice video. I would make a small change in the phylogenetic tree that you showed in the beginning of the video. Urochordates are more close to vertebrate as they share more recent common ancestors. Urochordates are sister group of Vertebrates whereas cephalochordate is a basal group.
Aganatha and Ostiecthyes are not classes. They are superclasses. Aganatha contains the class myxini or hagfish and petromyzonthida or lamprey. And superclass ostiecthyes contains the class actinopterigii or ray finned fish and Sarcopterygii or lobe finned fish which for some reason surprisingly includes the superplass tetrapoda.
I see you're missing all extint groups and some of existing ones, would you say this lecture is best suited for a highschool level or a bachelor level? If it is for a bachelor level i might watch it entirely.
This video is AMAZING. I have an exam coming up and my professor just reads off the slides and doesn't actually teach- thank you so much for this!!!

Alok Javali Urochordates can't be closer to vertebrates than cephalochordates. Somites are developed only in vertebrates and cephalochordata.
I'm replying cuz it's weird. Hello 2014 person.
No other words, just much thanks.
Cheers Bro ! helping me pass biodiversity :)

fantastic video! concise and very helpful! thanks for posting it.
best videos ever seen it help me alot i pray may GOD BLESS YOU with ISLAM
Thaks for help us... could you suggest some biology book for fundamental
I need the invertebrate diversity: introduction

Why are all the other animals squished together yet the chordates get their own video?
What about hemi-chordates?
shauda19 They are not monofiletic with the other chordates according to new information.
Hemichordates come under Invertebrata
awesome video.
very good lecture.
awesome! This helped me a lot!
Is it when a human is an embryo?
Thank you sooo much!
Beautiful
I thought lancelets were mituckys
it's good and very helpful but I wish for better image than this :)
Ok
At what point in life does a human have a tail? B/c humans are chordata.
It is indeed more prevalent when we are in embryonic state. But even as adults we have our tailbone as proof of our ancestral tail :)
Chordates cartilages vertebrates
Vertebrate Diversity? More like "exclusively 4 leg diversity" amiright guys?

really boring
so true lol
lol
hello
are u gonna fy76
1 why you watching if it’s boring and 2 why are you talking to your self
