Members of this phylum first appeared rather early in zoological history.
In addition, their limited ability to migrate, their dependence upon stable conditions of moisture and shelter, and their general intolerance of seawater, together with the fact that they appeared rather early in geological history and have since evolved little, make the myriapods important indicators of land-water relationships.
The first sure traces of an influence of al-Ghazali on Judaic thought appeared rather early, around 1160, when Abraham Ibn Daud employed his major philosophical work, The Intentions of the Philosophers, as one of the main unavowed sources of his Exalted Faith (see Eran 1998, 27).
The atrophy of quadriceps thus seems to appear rather early and to persist in untreated chronic ACL-deficient patients [ 3].
First particularly high increase of extractability of the components in question appeared rather early in the course of the repair process which fell on the 3rd day of healing in damages rinsed with NaCl and on the 5th day of the repair in wounds treated with SSD.
At the very least, probably a few more did too (since the odds on us finding the very first ones to get feathers are pretty tiny) and some fairly weak evidence suggests that feather may have appeared rather earlier in evolutionary terms, suggesting a few more theropod groups had them too.
The maze-like network of blood vessels appears rather chaotic in the earlier growth stages (lower part of figure), and settles into a more layered pattern later on (upper part of figure).
Kinesins move with a hand-over-hand action, it appears, rather than an inchworm gait as an earlier report suggested.
The equation appears rather simple.
While this notion appears rather weak, it is surprisingly useful.
