Primeval Kinship: How Pair-Bonding Gave Birth to Human Society

Sooner or later during evolution—from a primeval social association of early hominids—all human societies, prior and current, could emerge. during this account of the sunrise of human society, Bernard Chapais indicates that our wisdom approximately kinship and society in nonhuman primates helps, and informs, principles first recommend by way of the celebrated social anthropologist, Claude L?

Reprinted with permission from AAAS. emergence of oak leaves (Quercus robur) and of winter moth caterpillars (Operophtera brumata), which feed on the oak leaves and are a key food for nestling tits. The rates of change of egg laying date with temperature (Fig. 11c) and of caterpillar emergence with temperature (Fig. 11d) are similar, so the tits have closely tracked the temporal changes in food availability over almost five decades. How have the tits managed to do this? For temperate breeding birds, an increasing photoperiod in the spring is the primary proximate cue that initiates gonadal growth and the hormonal changes involved in breeding.

Esther Cullen, one of Niko Tinbergen’s research students, showed that a comparison with the breeding traits of a cliff-nesting gull, the kittiwake (Fig. 1b), provided comparative support for the anti-predator hypothesis. Kittiwake nests are safer from mammalian predators, who cannot so easily climb down steep cliffs, and they are also safer from avian predators because the gusty winds around the cliffs make attacks from the air more difficult. The different breeding traits of the kittiwake, compared to the black-headed gull, make (b) Fig.
