This where some have a different view of how animals can change over time. Take the horse example used. It shows pictures of a horse like creature. Apart from size and a couple of other features like the amount of toes and the placement of teeth they all look similar. Nothing in their changes cant be accounted for in variation with that horse species. The fossil record is actually more complicated than what those pictures show with the horse evolution. It is actually more like a bush pattern than a singlular line of changes like evolutionists try to paint. The patter shows that its not just a case of the horse going from small to the larger horse we have today. It shows that at times their sizes decreased and then increased only to decrease again.
Non evolutionists have the view that each creature doesn't stem back to common ancestors and originally all stem back to a common ancestor like a tree of life with a single trunk. The view they have is that there was many stems that represented many different animal types. Like the dog type that includes wolves, coyotes, jackals, dingos and domestic dogs. However, dogs are distinctly different from, and unrelated to, other groups (e.g. cats, bears, weasels). But with those original types of animals they had all the genetic info already there sitting dormant to allow for all those changes like the reduction of toes for horses or the changes in teeth ect.
The Basic Type concept has been applied to horses, both living and extinct forms (Cavanaugh
et al 2003; Garner 1998; Stein-Cadenbach 1993). These studies suggest that all horses, including the 150 or so fossil species, are probably related in a single Basic Type. The ancestor(s) of these horses probably possessed latent (i.e. unexpressed) genetic information that gave the horse type tremendous potential for variety. One way in which this latent genetic potential may be regulated is by differential gene expression. By this we mean that in living organisms there are mechanisms by which genes can be turned on (i.e., expressed) or turned off (i.e., not expressed). For example, horses may have a genetic switch that determines whether they develop side toes. Other regulatory genes may control size, shape of the teeth, and so on.
It appears that modern horses retain the genetic potential for extra toes, but that regulatory genes switch off the structural genes for side toes during embryological development. Occasionally, something goes awry with this regulatory mechanism and foals are born with side toes (e.g., Marsh 1879, 1892; Struthers 1893).
This seems consistent with the mapping of the genome. Scientists have found that the so called junk DNA may have more function than first though possible.
