(1) Ecological and taxonomic research : Kase, Hayami, Hanai, Tabuki, and Mori have found a peculiar primitive invertebrate faunas in the submarine caves in the tropical and subtropical Western Pacific. They collected many live and dead samples of the faunas and analyzed their ecological and taxonomic characteristic as a basis for future evolutionary researches.(2) Developmental biological research : Tanabe has investigated the mode of embryonic shell development in the primitive ectocochliate cephalopod Nautilus with the help of Mr. K.Uchiyama of the Toba Aquarium, and recognized a disks-shaped univalved organic shell (cicatrix) in the early stage. A similar shaped disk-shaped or low cap shaped primary shell is also known in extant Monoplacophora, suggesting their phylogenetic relationships.(3) Molecular systematic research : Endo, Ueshima, Ozawa, and Chiba have conducted DNA analysis of some primitive invertebrates such as brachiopods and stalked crinoids to establish their phylogenetic relationships at higher taxonomic levels.(4) Theoretical research : Chiba constructed numerical models to explain the log-term phenotypic-level evolution based on the theory of quantitative genetics.

（1）生态和分类学研究：Kase、Hayami、Hanai、Tabuki和Mori在热带和亚热带西太平洋的海底洞穴中发现了一种奇特的原始无脊椎动物群。他们收集了许多动物群的活体和死亡样本，分析了它们的生态和分类特征，为未来的进化研究奠定了基础。（2）发育生物学研究：田边在原始外甲类头足类鹦鹉螺的帮助下研究了胚胎壳发育的模式。鸟羽水族馆的 K.Uchiyama 先生，在早期就识别出了圆盘状的单瓣有机贝壳（疤痕）。现存的单板纲动物中也存在类似形状的盘状或低帽状初级壳，这表明它们的系统发育关系。(3)分子系统研究：Endo、Ueshima、Ozawa和Chiba对一些原始无脊椎动物如腕足动物进行了DNA分析和跟踪海百合，以在更高的分类水平上建立它们的系统发育关系。（4）理论研究：千叶构建了数值模型来解释基于数量遗传学理论的对数表型水平进化。
