In a conclusion, there were a considerable proportion of relict and remnant elements which can be traced back to Mesozoic, and even Paleozoic, as well as typical ancient endemism. All of these fully showed evolutionary conservatism and phylogenetic antiquity of the Alsophila spinulosa community during the process of vegetation evolution.

Amphioxus, a cephalochordate, is believed to be the closest living relative of the vertebrate. It is often regarded as an important model animal for phylogenetic studies on the evolution of animals from invertebrate to vertebrate.

文昌鱼是头索动物，被认为是现存的与脊椎动物最接近的无脊椎动物，经常被看作是分析从无脊椎动物到脊椎动物进化过程的一种重要的模式动物。

These five strains were identified as Bacillus cereus、Acinetobacter calcoaceticu、Pantoea agglomrans、Pseudomonas putida and Pantoea ananas by 16S rDNA gene sequence phylogenetic analysis, respectively. These bacteria species is the first reported in oilseed rape rape.

The main groups from PCR-RFLP analysis were identified by 16S rDNA gene sequence phylogenetic analysis.16 species were obtained, they were: Bacillus cereus、Mycoplana bullata 、Acinetobacter calcoaceticus 、Acinetobacter baumannii 、Chryseobacterium indolthetium、Acidovorax avenae、Pantoea ananas、Pantoea agglomerans、Pantoea dispersa、Pantoea spp.、Enterobacter cowanii、Sphingobacterium multivorum、Pseudomonas putida、Pseudomonas fulva、Pseudomonas parafulva and Pseudomonas spp., respectively.

通过16S rDNA 序列系统发育分析，5 个菌株分别被鉴定为蜡状芽孢杆菌、乙酸不动杆菌、成团肠杆菌、恶臭假单胞杆菌、成团泛菌属，作为内生细菌存在于油菜体内属首次报道。

Phylogenetic relationships among these families and within the Hamamelidaceae have been key questions in studies of angiosperm systematics and evolution.

这些科之间的谱系关系以及金缕梅科内部的谱系关系是研究被子植物系统和进化的主要问题之一。

We reviewed the researches on the Asian Paleogene euprimates of the past 80 years, and suggested a new definition of Anthropoidea within phylogenetic systematics.

Based on phylogenetic analysis, this paper reviewed the relationship between hormones including sex hormones and AVT, and vocal production and perception through all anuran species studied to date. We found that in anuran brains the AVT system related to vocal behaviors were very conservative while the sex hormone systems involved in vocal communication might be originated independently from varied taxa of anuran.
