Abstract:
We propose that domestication is the result of interspecies cooperative breeding. Considering domestication as an outcome of cooperative breeding can explain how domestication occurs in both plants and animals, encompass cases of domestication that do not involve humans, and shed light on why humans are involved in so many domesticatory relationships. We review the cooperative breeding model of human evolution, which posits that care of human infants by alloparents enabled the evolution of costly human brains and long juvenile development, while selecting for tolerance of strangers. We then explore how human cooperation in the protection and provisioning of young plants and animals can explain the evolution of domestication traits such as changes in development; loss of aggressive, defensive, and bet-hedging aspects of the phenotype; and increased fertility. We argue that the importance of cooperative breeding to human societies has made humans especially likely to enter into interspecies cooperative breeding relationships.
摘要:
我们认为驯化是种间合作育种的结果。将驯化作为合作育种的结果可以解释驯化是如何在植物和动物中发生的,包括不涉及人类的驯化案例,并阐明了为什么人类参与了如此多的驯化关系。我们回顾了人类进化的合作育种模型,这表明,通过同种异体父母对人类婴儿的照顾能够促进昂贵的人类大脑的进化和长期的青少年发育,同时选择对陌生人的宽容。然后,我们探讨了人类在保护和供应幼小植物和动物方面的合作如何解释驯化特征的演变,例如发育的变化;丧失侵略性,防御性,和表型的赌注对冲方面;和增加的生育率。我们认为,合作育种对人类社会的重要性使人类特别有可能进入种间合作育种关系。
