The middle-ear bones in mammals, for example, have their origins in the reptilian jaw.
Mammals, for example, will not bite with full force if it might hurt their teeth.
Pupils will start with simple concepts of change, adaptation and natural selection illustrated by the evolution of fish to amphibians to mammals, for example.
"Mammals," for example, were so named by Linnaeus, in the eighteenth century, because their females produce milk to suckle their young.
Hormonally controlled colour changes also occur in mammals; for example, swellings in the genital areas that become pink due to vascularization during the reproductive season.
Death in human beings and other mammals, for example, often results directly from heart or lung failure, but the preceding sequence of events may be highly complex, involving disturbances of other organ systems and derangement of other control mechanisms.
Some orbiviruses cause disease in mammals (for example, blue-tongue disease in sheep); rotaviruses have been implicated in infective infantile diarrhea; and phytoreoviruses can destroy rice, corn, and other crops.
In marine seals, antelopes, baboons, and many other mammals, for example, a dominant male may keep a large harem of females at the expense of many other males who can find no mates.
While there are a few other examples of cleaning behavior among terrestrial creatures — small birds that eat parasites off large mammals, for example — the researchers say the mite-bee interaction is among the most clear-cut cases of this kind of mutualism on land.
In mammals, for example, chromosome structure predicts the sex of the adult animal.
