There are many things we don’t know about animals, although we can learn something from them. Today, we’ll talk about how animals sleep.
In order to keep up with a changing environment, mobile organisms must be capable of deciding both where and when to move. This precision necessitates a strong sense of time, as otherwise we would fail in many of our movement goals. Yet, despite this intrinsic link, only recently have rese...
However, the principle of a self-destructive mechanism blocked by upstream regula- tors and activated by multiple, diverse stimuli does indeed mirror that of apoptosis. Why it should be evolutionarily beneficial to have a self-destruct mechanism for rapid axon loss remains unclear but possible ...
1). Further, postural kinematics have been described for many species in this group, and rather than being related to size as is the case for mammals [4], posture appears to be more closely related to climbing habitat [17]. Terrestrial varanids display increased femur adduction, femur ...
Interestingly, in many cases the 'new' function of one copy is a secondary property that was always present, but that has been co-opted to a primary role after the duplication. This is a preview of subscription content, access via your institution Access options Subscription info for Chinese...
