Such successive species in the evolutionary sequence are called chronospecies.
An exhibition of botanical paintings from the Shirley Sherwood Collection, innovatively laid out in the latest evolutionary sequence revealed by DNA analysis.
All past and present societies could be arranged in an evolutionary sequence.
The subsequent evolutionary sequence led to losses and specializations of the incisors and canines.
The evolutionary sequence of the bird orders starts with ratites and marine seabirds and ends with songbirds.
The latter steady state, or dynamic equilibrium, situation will then continue with little topographic change until the prevailing conditions cease or are disrupted, so that a new evolutionary sequence can begin.
The fifth digit of the hindfoot was the next to disappear in the evolutionary sequence, and all known forms beyond the lower Oligocene had only three toes in each foot.
Its genera Cordaites and Cordaianthus are represented by fossil leaves, branches, and loosely formed cones, investigations of which have led to the formulation of the cordaite-conifer evolutionary sequence through the primitive conifer family Lebachiaceae (see Lebachia).
Important, too, is the fact that the evolutionary sequence of organisms based on the large fossil remains of plants in sedimentary rocks is recorded by the sequence of plant microfossils as well.
The team produced a kind of molecular clock by establishing an evolutionary sequence for single-domain proteins.
This evolutionary sequence is situated on top of a fluvial terrace staircase capped by a 1.3 Ma (40Ar/39Ar plateau age) lava flow.
