This negative argument against step by step evolution ignores longstanding evidence that evolution proceeds through changes of function from preceding systems.
At equi-efficacious doses of TAM and EE (i.e. 100 vs. 20 μg/kg, respectively), comparable effects on UWW, luminal circumference and glandular epithelial were observed (data not shown), suggesting both treatments proceed through similar changes to achieve uterotrophy.
Starting in the third instar larval stage, developing wing blade cells lack expression of Ubx and proceed through several morphological changes.
Lasker's realization that the cure for a disease could proceed through political action changed the rules of the game.
The mutant cells then proceed through a series of morphological changes prior to their clearance from the retina.
These changes may proceed through the loosening of the lower esophageal sphincter, which would allow gastric contents to reflux more easily [ 8] and augment airway hyperresponsiveness through the vagal reflex [ 36, 37].
Fitness improvements soon after invasion may proceed through many steps with wide changes in virulence, because fitness depends on transmission as well as virulence, and transmission improvements can overwhelm nonoptimal virulence.
As RecA does not interact with SSB, RecO, or RecR (Umezu et al., 1993), this activity must proceed through a RecOR-induced conformational change in the SSB-ssDNA complex (Ryzhikov et al., 2011; Zhou et al., 2011).
Development of human cancer can proceed through the accumulation of different genetic changes affecting the structure and function of the genome.
