How 'smeared' do you want it?

This quote here summarises what I am talking about.
'Although an almost incomprehensible number of species inhabit Earth today, they do not form a continuous spectrum of barely distinguishable intermediates. Instead, nearly all species can be recognized as belonging to a relatively limited number of clearly distinct major groups, with very few illustrating intermediate structures or ways of life.' Robert L. Carroll, Patterns and Processes of Vertebrate Evolution, Cambridge University Press, 1997, p. 9
Evolution predicts a genetic smear. Creation predicts distinct groups and variation within groups.

Horse evolution: you get a bunch of fossils of similar and vaguely similar creatures from places all over the world and put it together into a sequence. Hey Presto, you have one of the showpieces of evolution!
As for the vesigal 'toes' on the horse this article shows they are not vesigal at all!

'Horses and camels have muscles in their legs with tendons more than 600 millimetres long connected to muscle fibres less than 6 millimetres long. Such short muscles can change length only by a few millimetres as the animal moves, and seem unlikely to be of much use to large mammals. The tendons function as passive springs, and it has been assumed that the short muscle fibres are redundant, the remnants of longer fibres that have lost their function over the course of evolution. But Wilson and colleagues argue… that these fibres might protect bones and tendons from potentially damaging vibrations….
Their experiments show that short muscle fibers can damp the damaging vibrations following the impact of a foot on the ground. When the foot of a running animal hits the ground, the impact sets the leg vibrating; the frequency of the vibrations is relatively high-for example, 30-40 Hz in horses-so many cycles of vibration would occur while the foot was on the ground if there were no damping.
The vibrations might cause damage, because bone and tendon are susceptible to fatigue failure. Fatigue in bones and tendons is the accumulation of damage resulting from repeated application of stresses. Bone fatigue is responsible for the stress fractures suffered by both human athletes and racehorses, and tendon fatigue may explain at least some cases of tendonitis. Wilson et al. suggest that the very short muscle fibres protect both bones and tendons from fatigue damage by damping out vibrations' R.

This is the 'molecular clock' idea, whereby over time DNA accumulates changes. I think according to this site http://www.rtis.com/nat/user/elsberry/evobio/evc/argresp/sequence.html , the sequence roughly follows what we would expect from an animal's taxonomy. To me this is just as easily fit into common design as common ancestor.
The weakness is, as you would expect the clock is calibrated using fossil evidence, which has an assumption of evolution. Also, evolution may not nessecarily proceed at a constant rate.
I think you'll find that we share rather less than 97% of our DNA with the humble cockroach :hihi.
