So your source (implicitly) argues that the rate of change in putatively neutral molecular characters (selected regions of the DNA) is roughly constant -- this being how the time of divergence between the two existing populations of coelacanth was determined -- whereas morphological evoltution is not necessarily constant in rate, and can even halt for long periods.

I agree and see no problem with this.

Another point in the reference was that morphological differences observed by the first team between the two species were not observed to be there when compared to the variation in one of the species.(my wording may be bad)
