There have been two separate unrelated domestication events for the Domestic Horse. The horses of the second event are the ones we have today. it is believed that the first event horses turned feral, and became E.f. przewalskii.

Not quite; the paper which claimed this was based on pretty shaky assumptions, not even considering the much more likely option that the Botai horses represent a domestication event so recent (at the time of their existence) that their genome had not yet diverged from their wild kin.

If i recall correctly, Chester's birds are pure rock pigeon/rock dove, meaning that this photo shows the correct taxon: Rock Doves (Columba livia) Mating | ZooChat
I may be mistaken though, so let's wait to see if anyone confirms/corrects that :p

I do not think that they are pure. I disliked one specimen at Chester so much that I deleted a decent photograph of it - which was stupid, as it would have proved my point now. This bird had partially-feathered tarsometatarsi, which can also be seen in the female in bongorob's photo. I'm sure this indicates that they have some genes from domestic pigeons.

The original purpose of domestication was for carrying messages?? Where are you getting your information from?

That's not how taxonomy works. "Scientists" don't just use something as a "filler species" when they don't know an ancestry.

The information very well may be wrong. I'll do some more research, but fell free to change it if you know the actual information. :)

Thomas' Camel is sort of a "filler species". It's the name scientists use to refer to the ancestor of the Dromedary.

No, it really isn't :p it is the taxonomic name for a species which was present in North Africa and the Middle East during the late Pleistocene and which has been proposed as a candidate for the wild ancestor of the Dromedary; however the species differs from the latter in several distinct aspects including size and cranial dimensions. Other proposed origins for the Dromedary include a second domestication event from Camelus ferus in addition to the one which led to the Bactrian Camel, hybridisation between C. thomasi and C. ferus, hybridisation between C. thomasi and C. bactrianus, and domestication from a wild ancestor distinct from either C. ferus or C. thomasi, potentially synonymous with the patchily known extinct subspecies Camelus dromedarius dahli.

Doing any research would be a good start.

The "dogs are not descended from wolves" theory as proposed by Manwell & Baker has been pretty soundly discredited in recent years, as a result of comprehensive molecular sequencing and research published by several researchers - most recently Freedman et al and Larson et al. These demonstrated that the domestic dog is deeply nested within Canis lupus.

As such, in this case he is correct not to edit his original statement.

That second link isn't working for me, but thanks. I haven't seen that before. However, the first link doesn't support the idea that dogs originated from gray wolves instead of them both being from a common ancestor. Two relevant quotes:

"Thus regardless of our assumptions on the identity of the wolf population from which dogs originated, we infer that dogs diverged from the sampled wolf populations at about the same time these wolf populations diverged from each other."

"Another alternative is that the wolf population (or populations) from which dogs originated has gone extinct and the current wolf diversity from each region represents novel younger wolf lineages, as suggested by their recent divergence from each other (Figure 5A). Our inference that wolves have gone through bottlenecks across Eurasia (Figures 3B, 5A) suggests a dynamic period for wolf populations over the last 20,000 years and that extinction of particular lineages is not inconceivable. Indeed, several external lines of evidence provide support for substantial turnover in wolf lineages."

The two other alternatives were both described as "unlikely".

Actually, the very quote you highlighted supports the former hypothesis:

"Thus regardless of our assumptions on the identity of the wolf population from which dogs originated, we infer that dogs diverged from the sampled wolf populations at about the same time these wolf populations diverged from each other."

To put this quote another way....

A = Dog
B = Wolf 1
C = Wolf 2
D = Wolf 3

If the last common ancestor of B, C and D (X) occurred at the same time as the last common ancestor of A and B/C/D (Y), implicitly X and Y are one and the same and the only way to maintain Canis lupus (B/C/D) as a monophyletic unit is to include A within the species.
