| Abstract: | Based on the Bayesian phylogenetic tree of cytochrome b gene complete sequences, the evolutionary pattern and process of two character pairs in Gallopheasants are comparatively studied by means of likelihood ratio tests. The result reveales the correlation of habitat structure and altitudinal distribution. The co evolution pattern is obvious in the character pair of age of full sexual maturity and egg size; temporal order analysis showes that the former is prior to the latter in the evolutionary process. This conclusion indicates the transition of life history type in Gallopheasants. |
