Specifically, his claim that horses are evidence of macroevolution.
Where are the transitional fossils connecting Eohippus with Mesohippus ?
Or is it assumed ?
Where are the transitional fossils connecting ANY of the horse species in the image ?
Or is it assumed ?
Or should I say Darwinian faith operating in the gaps ?
The image shows the existence of different quadrupeds who have similarities - not evidence of relationship between them.
If the image is accurate showing straightline evolution, then why have horses grown shorter than before and why doesn't the image reflect this fact ?
What scientifically connects the species other than speculation ?

Gidday Evidence,
Ed Vdence (wrt Loudmouths post) said:

There is only one discovered and purported transitional - Orohippus. I say purported because it cannot be said that Orohippus necessarily connects Eohippus with Mesohippus. All that can be said is that it shares features with both.
Perhaps there are other fragments of bone which cannot be categorized as yet, but which may connect the fossils.
That there are further transitionals is a prediction of ToE. As such it tells us what to look for and where to look. What to look for are bones that share characteristics of both preceding and later animals. Where to look is in geological strata that fit the right period.
Whether the transitionals can be found depends on several things:-
1) Their preservation. Examine the diagram Loudmouth presented and note the unconformities. You do understand the significance of these, dont you? Furthermore, how many buffaloes ever lived in the U.S? What do you think your chances are of just picking up a shovel, going into the country side, digging then finding a buffalo skeleton? Not likely I would say, yet an accumulated number of billions of them inhabited the US only yesterday and their skeletons would have been unravaged by geological processes.
2) People looking in the right place. Once we only had modern horses. Then, around the late 1830s we had Eohippus. Now we have the range displayed in Loudmouths post. IOW, it takes time to do this.

Those transitionals are predictions of the theory. The existing transitionals are evidence for the viability of the theory as it now stands.

See above.
Ed Vdence said:

No. The Darwinian faith explains the pattern and predicts that further transitionals will be found, providing geology has been kind. Geology tells us where to look and at what period. It tells us why we may or may not be successful.
Do you call all scientific theories faiths or only those you dislike? If you called all theories faith then you would be consistent. However, (I suspect that) you pick and choose just what you do decide as faith hence at least you are not consistent.

On what grounds do you make this claim?

Who said that the image was meant to be an accurate portrayal of the nature of evolution (e.g. straight line vs branching, gradual vs punctuated)?

Observation and theory. These fossils fit into the universal phylogenetic tree which itself has been constructed from many and independent sets of data. A universal phylogenetic tree is one outcome of common descent with modification.
