The form of reproductive senescence seen in Allonemobius, that of a changing in the quality or size of ejaculate as males age, can be found in animals ranging from insects [e.g.], [48], [49] to mammals [e.g.], [50], [51] and would appear to be a common form of male reproductive senescence.
Furthermore, as would also be predicted under a mosaic model of evolution, our results suggest that specific structures can be the target of selection, rather than all structures changing in size simultaneously, since the second and third principal components appear to separate species based on sensory specialization.
Humanity is changing in both size and shape.
The spatial scan statistic tests whether the cases are evenly distributed among the background population, by comparing the risk of an animal being infected inside a moving window (changing in size and shape) to the risk outside this window.
Not only that, but as with so many of these features, one can see the feathers changing in size and structure over time in a clear and consistent pattern.
Evolving (changing) in size, shape, color, how much above the skin surface they are raised etc).
Campbell explained that the nets would not be changing in size from crossbar to posts, but that they would be shallower, allowing for more room behind the net.
The looming and the receding visual signals consisted of a centered gray disk changing in size from 2 to 5 degrees and from 5 to 2 degrees of visual angle, respectively.
