In these circumstances, shaking the head would seem to be a very natural response and from this to shaking immediately before a grip can be established, is a minor change. In Dasycercus, shaking the prey is le~s fully built into the feeding pattern than it is in the two viverrids and it does not appear when dead food or quite innocuous prey is being dealt with: the same is true of Sminthopsis.

The vanquished contestant's aim is only to hold his attacker at bay until an opportunity for escape offers and so his expressions are defensive rather than submissive. may originate in various ways, but if it once comes to act as a signal which is responded to by other members of the species, then a new selective force comes into play. If it is advantageaus foraquick and correct response to be made, then there will be selection for making the signal more obvious and unmistakable.

If a cow is transferred to such an area from grassland, it at first becomes very thin and may take a few months before it adapts itself fully to the new circumstances, which entail a change not only in the food eaten, but in the manner of cropping it. It is, of course, their adaptability in this respect that makes mammals important as agricultural pests. If man cultivates a rich crop of some nutritious food stuff, it is only tobe expected that some of his fellow mammals will presently take advantage of it.
