Equus quagga quagga (Quagga)

[another specialist]

Sorry RSN i know you know i was using it to establish/tell everyone where the info come from originally and supply you the information i found by giving you the link to the pdf file. Just supplying you what you was asking for...........

[RSN]

Oh, don't worry about it. Thanks for the pdf link.

[another specialist]

ok RSN no probs here

Never heard of it before. Onle one name that looks similar: Equus quagga isabella (Ziccardi, 1958). The possible valid maneless Somali subspecies. But I don't think it is the same.

[Peter]

Looking at the images, I think it looks indeed like Equus quagga burchellii (synonym: Equus quagga antiquorum). The image is not good (which is often in such paintings, especially old ones), but you can see the stripeless leggs, but the still striped back.

thanks for the above pics and comparasion

Zebra of a Different Color

The quagga, which looked like a cross between a horse and a zebra, was hunted to extinction 100 years ago, but scientists aren't done with it yet. A DNA analysis of 13 museum specimens, conducted by Smithsonian scientists and others, shows that quaggas split from zebras 120,000 to 290,000 years ago, probably during an Ice Age.

Very interest Peter about zebra of a different colour

So had been split for a pretty long time plenty of time to evolve into some different

A rapid loss of stripes: the evolutionary history of the extinct quagga

Jennifer A. Leonard A, Nadin Rohland A, Scott Glaberman A, Robert C. Fleischer A, Adalgisa Caccone A A, Michael Hofreiter A

Abstract:
Twenty years ago, the field of ancient DNA was launched with the publication of two short mitochondrial (mt) DNA sequences from a single quagga (Equus quagga) museum skin, an extinct South African equid (Higuchi et al. 1984 Nature 312, 282–284). This was the first extinct species from which genetic information was retrieved. The DNA sequences of the quagga showed that it was more closely related to zebras than to horses. However, quagga evolutionary history is far from clear. We have isolated DNA from eight quaggas and a plains zebra (subspecies or phenotype Equus burchelli burchelli). We show that the quagga displayed little genetic diversity and very recently diverged from the plains zebra, probably during the penultimate glacial maximum. This emphasizes the importance of Pleistocene climate changes for phylogeographic patterns in African as well as Holarctic fauna.

Why some quaggas have stripes in the back and others not? I still didn`t understand it!

[another specialist]

Well simply variations just like us for example no two are exactly the same we all look different in same way.

Mitochondrial DNA of the extinct quagga: relatedness and extent of postmortem change.

Higuchi RG, Wrischnik LA, Oakes E, George M, Tong B, Wilson AC.
J Mol Evol. 1987;25(4):283-7

Abstract:

Sequences are reported for portions of two mitochondrial genes from a domestic horse and a plains zebra and compared to those published for a quagga and a mountain zebra. The extinct quagga and plains zebra sequences are identical at all silent sites, whereas the horse sequence differs from both of them by 11 silent substitutions. Postmortem changes in quagga DNA may account for the two coding substitutions between the quagga and plains zebra sequences. The hypothesis that the closest relative of the quagga is the domestic horse receives no support from these data. From the extent of sequence divergence between horse and zebra mitochondrial DNAs (mtDNAs), as well as from information about the fossil record, we estimate that the mean rate of mtDNA divergence in Equus is similar to that in other mammals, i.e., roughly 2% per million years.

Thanks for the info Carlos - of great interest.

This is my first post so hello everyone. I am an illustrator/designer and have had a long time interest in nature; recently extinct animals are a fascinating subject from my point of view as any imagery you produce requires so much research. The following is an image I recently completed of a Quagga:



It isn’t perfect and I haven’t considered the legs in too much detail yet. The initial drawing was created referencing the following sources: Quagga photos from London Zoo, The mounted specimen in the Natural History Museum and Burchells Zebra photos from the Quagga project. The following was also referenced: ftvdb.bfi.org.uk/sift/title/596401 You may find the program intresting if you can find a copy of it.

I know you take contributions, if you think the image would add something to the main Quagga page on the website you are more than welcome to use it, Just drop me a pm. I can provide it up to a maximum size of A3.

Kind Regards

Jon
edit: for better legs!

Welcome to the forum Jon. I like your quagga, even if it is not finished... yet

Really beutiful John!

@ Jon,

Hi and Welcome !

Is this Quaqqa made by the computer ?

[another specialist]

Great image John

Kep up the good work and welcome to the forum.

[vsa01]

Thankyou for all the nice comments, I will definatly do more!

Alex, The quagga is hand drawn & Coloured in pencil, This is then scanned & adjusted using photoshop in order to get the best shape. More detail is then added using Photoshop to give depth and a deeper range of smooth colour. So yes and no is the answer to your question - I would say that both are equaly as important.

Regards

Jon
