家禽起源与驯化研究进展

随着全基因组扫描技术的突破及学科交叉互动,近年来家禽起源、驯化研究取得了一些重要进展。家禽为人类提供肉、蛋及羽绒,也用于宗教礼仪及文化生活。在人类文明进程中驯养家禽占据不可或缺的地位。分子生物学技术及考古学研究表明,家禽驯化是一个复杂而漫长过程,家禽适应人类改变了形态、行为及生理,人类因家禽出现改变了饮食结构及行为方式。家禽来源于野生物种,不同的家禽在不同地点由不同族群独立驯化而成,驯化过程伴随其他物种基因渗入。揭示家禽起源不仅是一个科学问题,对保护家禽遗传多样性及遗传育种都有重要意义,未来全基因组扫描及花粉考古有望成为家禽驯化研究热点。

Progress on the Origin and Domestication of Poultry

Advance with breakout in genome-wide association study and cross in multidiscipline,study on origin and domestication of poultry had made great progress in recent years.For thousand years,poultry had been used for food,ritual and entertainment for human.Poultry played indispensable roles during cultural history.Study with molecular biology and archaeology revealed lengthiness and complexity of poultry domestication.The process of domestication involves adaptation to a captive environment with changes in mor...
