SciShow: How Different Animals and Insects Visually Process the World Around Them

This is a fun and pretty accurate Youtube video on how different animals (vertebrates and invertebrates) visually process the world.  There is so much to learn from the evolution of the eye and we here on Webvision are always happy to see basic science and the science of vision being communicated to the wider public.

Note: I first saw this on a Laughing Squid blog entry. Lori Dorn posts the best articles there.

How Animals And Humans See The World Differently

There is a short video from National Geographic that is a companion to an article by Ed Yong (@edyong209) in National Geographic here.  The photography is wonderful as is typical of National Geographic and is well worth your time.

For a more detailed read on the evolution of vision, be sure to check out this Webvision chapter by Trevor Lamb, Evolution of Phototransduction, Vertebrate Photoreceptors and Retina.

The Mystery of Neanderthal Large Eyes

The extinct Neanderthals had orbital eye sockets that are much larger than ours.  Recently, there has been an discussion covered in a fascinating article linked the other day on the BBC discussing the large orbital eye sockets of the Neanderthals and whether these eye represented a reason for the Neanderthals’ demise or not.

Helga Kolb noticed an interesting discussion about this from two other pioneers of vision research, Bill Stell and Clyde Oyster his resulted in some interesting commentary between them on their Facebook accounts. Continue reading “The Mystery of Neanderthal Large Eyes”

TEDEd Evolution Of The Human Eye

There is a great TED-Ed video on “The Evolution of the Human Eye” with some very clever animation.  The video itself is short and geared towards the college level, and while some of the conjecture at the end contains some far out statements, it is a fun few minutes.

 

Evolution Of The Avian Visual System

There is a great online chapter covering the Evolution of the Avian Visual System by Scott Husband and Toru Shimizu covering everything from brain evolution in dinosaurs to retinal structure and post retinal pathways.

Also, if evolution of visual systems interests you, don’t forget to read the Webvision chapter Evolution of Phototransduction, Vertebrate photoreceptors and Retina by Trevor Lamb.

Evolution of Sight in the Animal Kingdom

This amazing video produced by the History Channel, Vision and Evolution of the Eye is well worth 40 minutes of your time.  The evolution of visual systems is something that we here at Webvision are very interested in.  Also note that we have an excellent chapter on the Evolution of Phototransduction, Vertebrate Photoreceptors and Retina by Trevor Lamb here on Webvision.

 

This accompanying text below on this post was sent to us by friend of Webvision, Dr. Dominic Man-Kit Lam.  Dr. Lam was born in Swatow, and grew up in Hong Kong. He studied under two Nobel Laureates at Harvard Medical School before joining the Harvard Faculty and subsequently became Professor of Ophthalmology and Chairman of Center for Biotechnology at Baylor College of Medicine in Houston. He is the president of the World Eye Organisation, A charitable organization dedicated to the prevention and treatment of eye disorders for the poor.  Continue reading “Evolution of Sight in the Animal Kingdom”
