    Notes: [Auszug] The Japanese quail (22 males and 13 females) tested in this experiment were obtained from eggs laid by four different pairs in our laboratory colony. Eggs from a given pair were collected over 2-week periods and placed simultaneously in a separate compartment in an incubator. When transferred 13 ...

    Notes: [Auszug] The quail were raised from hatching in four randomly assorted groups, each consisting of 10 chicks. At 35 d after hatching 20 males were isolated and when they were sexually mature, were given two types of test between 59 and 83 d after hatching. First, they were given an opportunity to approach ...

    Notes: [Auszug] Many plants and animals are capable of developing in a variety of ways, forming characteristics that are well adapted to the environments in which they are likely to live. In adverse circumstances, for example, small size and slow metabolism can facilitate survival, whereas larger size and more ...

    Notes: Abstract Two treatments of hooded rat (Rattus norvegicus) mothers after the birth of their pups affected the stage of development at which their pups started to take solid food and showed an increase in the expression of sucrase, an enzyme needed for digesting solid food. The pups of mothers that became pregnant in a post-partum oestrus showed the changes significantly earlier than those in the control group (Fig. 1A, B). The pups of mothers that had been mildly food-restricted after birth showed the changes significantly later than those in the control group. In brief, the pups of the pregnant mothers weaned first, the control pups next and those of food-restricted mothers weaned last. Differences in the timing of weaning between the three groups occurred in the absence of differences in pup body weight at the time of weaning. Within each experimental group, on the day in which sucrase expression showed the first detectable increase, sucrase activity was strongly predicted by the weight of the pups shortly after birth (Fig. 3). Pregnant mothers put on weight rapidly before implantation and their pups prepared for early weaning even though they did not differ in body weight from control pups (Fig. 4A, B). Food-restricted mothers were significantly lighter than control mothers and, with lighter pups before weaning started, settled for a longer period of suckling.

    Notes: Abstract Human propensities that are the products of Darwinian evolution may combine to generate a form of social behavior that is not itself a direct result of such pressure. This possibility may provide a satisfying explanation for the origin of socially transmitted rules such as the incest taboo. Similarly, the regulatory processes of development that generated adaptations to the environment in the circumstances in which they evolved can produce surprising and sometimes maladaptive consequences for the individual in modern conditions. These combinatorial aspects of social and developmental dynamics leave a subtle but not wholly uninteresting role for evolutionary biology in explaining the origins of human morality.
