AI Thread Summary
The discussion highlights various educational resources and websites focused on biology, particularly emphasizing animations and videos that illustrate biological processes. A notable mention is a time-lapse video of Xenopus toad eggs, showcasing embryonic development. Users share links to several sites offering animations, tutorials, and documentaries on topics like mitosis, evolution, and immunology. Recommendations include resources from the National Institutes of Health, educational platforms for biology and neuroscience, and specific videos on DNA replication and transcription. Participants express interest in high-quality visuals and seek additional resources for understanding complex biological concepts, particularly in immunology and brain evolution. The conversation encourages sharing of valuable educational content and resources across the biology community.

I like the book The Major Transitions in Evolution.
It discusses big evolutionary transitions from perspectives of hierarchical organization and information.
Advanced book, requires some pre-existing level of knowledge of evolution.

Take a look at this website, it has some really neat Clips, Stills, and Slides of small life forms:

http://www.cytographics.com/Especially nice is the video of Xenopus (toad) eggs. The video illustrate, how perfectly times embyonic development is, since three three eggs were fertilized at the same time and develop at the same speed.

It is cool, since it is a time lapse videa which shows the process from first cell division all the way of the hatching of the tadpole. Too bad the resolution is not so nice, I've got in on a CDROM which is 100x better.

I clicked on the website and it seems they have server problems. I also wanted access to high resolution images. I also clicked on CONTACT US and that did not work either. Do you have their contact details?

You might check the date(s) of the post(s) before leaping to too many conclusions.

Looks like the website is still up and the contact us should still work but you need to copy and paste the address into your email program. info[at]cytographics.com

Looking for immunology animations

I'm looking for a site with immunology animations that would be appropriate for students that are either non biology majors or have a very basic understanding of biology. I've looked at a few sites you guys have listed (some very cool sites) but haven't found one that gives a good general overview of the immune response cascade. If you know of good site please let me know!
Thanks

Try this: http://highered.mheducation.com/sites/0072495855/student_view0/chapter24/animation__the_immune_response.html

It's not comprehensive, but other websites have great animations, but you must purchase the textbook, which is rather pricey, like this one:

Hello people :oldsmile:

I have recently finished reading a wonderful book “Evolving Brains” by John Morgan Allman, it describes how brain evolved during the biological history.

This book is really good, but unfortunately it was published more than 20 years ago, so it does not contain new information and author did not publish its second, newer edition.

So, I am looking for another book, or perhaps (review) article(s) describing the same history. I am especially interested in its genetic aspect, more precisely which genes participated in developing/evolving brain. In Allman’s book just several genes were mentioned, for example BF-1, BF-2, Emx-1, Emx-2, Hox-b1, Hox-b2, Hox-b3, Hox-b4, Hox-b5. But nowadays of course much more such genes are discovered, so I want to be awared about them.

So, which book or article(s) would you recommend me? Of course I can try to search them myself, but such “blind” search probably will not be as good as your help :oldeyes:

Upon googling brain evolution books, I was surprised to see that were were a fair amount of them (have not looked into this in about 20 years or so. Some of them are rather expensive, so a better idea of what you are interested in would be useful.

Allman (as I recall) is more interested in big mammalian brains and the evolutionary forces that shaped them, as opposed to my interests in the histological (tissue organization and cellular level) details of how brains changed and how those changes were generated in development (using genes like the HOX genes).

There seem to be a lot of books on brain-consciousness and reasons for human brain evolution. These seem cheaper, probably because they appeal to a larger audience.

There are also some very old books/reviews on details how brain anatomy and tissue structure differ between various evolved forms.

There are some journals that specialized to brain evolution (such as Brain, Behavior, and Evolution). They should have review articles.
Annual Review books, like the Annual Review of Neuroscience or other related subjects, might have reviews on brain evolution.
Georg Striedter (editor of Brain, Behavior, and Evolution) also has what superficially looks like a couple good books to me (based on my interests), but they are expensive.
Principles of Brain Evolution and Brains Through Time: A Natural History of Vertebrates
Disclousure; I know this guy.

Rather than buying some expensive book, my top recommendation would be to go to a university where there some research interest in this subject (neurobiology and/or evolution) and look at what they have on the shelves.
This would also work for finding review articles on this somewhat obscure subject, unless you can find some that are open access.

You could also get a research gate account and search for articles in there.

Here is an open access article: Evolution of bilaterian central nervous systems: a single origin? that I would probably enjoy, but I am guessing it is earlier (in evolution) than your interests.

Actually I am looking for the genes that participated not in a brain’s whole evolution (this is a big topic) but in primates’s brains’ evolution. More precisely – which genes caused humans’ (ancestor’s) brain to develop compare to chimpanzee. In other words – brain’s evolution during recent 5-7 million years. I should have mentioned this circumstance in my previous post :oldsmile:

Thanks, I have already downloaded these books from internet.

Free download is better solution; in my country nobody will arrest me for this :oldeyes: “Brains Through Time” is so recent book, thanks!

For the time being Covid-19 makes this impossible :smile:

Still thanks :oldsmile:
