Journal ArticleDOI
Divergent Selection on Opsins Drives Incipient Speciation in Lake Victoria Cichlids
Yohey Terai,Ole Seehausen,Takeshi Sasaki,Kazuhiko Takahashi,Shinji Mizoiri,Tohru Sugawara,Tetsu Sato,Masakatsu Watanabe,Nellie Konijnendijk,Hillary D. J. Mrosso,Hidenori Tachida,Hiroo Imai,Yoshinori Shichida,Norihiro Okada +13 more
TL;DR: Parallel evolution in two cichlid genera under strong divergent selection in a gene that affects both is demonstrated, showing that the reciprocal fixation adapts populations to divergent light environments.
Journal ArticleDOI
Possible involvement of SINEs in mammalian-specific brain formation
Takeshi Sasaki,Hidenori Nishihara,Mika Hirakawa,Koji Fujimura,Mikiko Tanaka,Nobuhiro Kokubo,Chiharu Kimura-Yoshida,Isao Matsuo,Kenta Sumiyama,Naruya Saitou,Tomomi Shimogori,Norihiro Okada +11 more
TL;DR: Gain-of-function analysis revealed that FGF8 expression in the diencephalon controls patterning of thalamic nuclei, which act as a relay center of the neocortex, suggesting a role for F GF8 in mammalian-specific forebrain patterning.
Journal ArticleDOI
Mitochondrial phylogenetics and evolution of mysticete whales.
Takeshi Sasaki,Takeshi Sasaki,Masato Nikaido,Healy Hamilton,Mutsuo Goto,Hidehiro Kato,Naohisa Kanda,Luis A. Pastene,Ying Cao,R. Ewan Fordyce,Masami Hasegawa,Norihiro Okada,Norihiro Okada +12 more
TL;DR: The mtDNA analysis suggests that four lineages exist within the clade of Eschrichtiidae + Balaenopteridae, including a sister relationship between the humpback and fin whales, and a monophyletic group formed by the blue, sei, and Bryde's whales, each of which represents a newly recognized phylogenetic relationship in Mysticeti.
Journal ArticleDOI
Phylogeny and biogeography of highly diverged freshwater fish species (Leuciscinae, Cyprinidae, Teleostei) inferred from mitochondrial genome analysis
Junichi M. Imoto,Kenji Saitoh,Takeshi Sasaki,Takahiro Yonezawa,Jun Adachi,Yuri Ph. Kartavtsev,Masaki Miya,Mutsumi Nishida,Naoto Hanzawa +8 more
TL;DR: Important roles for the continental rearrangements during the Late Cretaceous to form the present-day distribution of organisms are suggested.
Journal ArticleDOI
Balaenoptera omurai is a newly discovered baleen whale that represents an ancient evolutionary lineage
Takeshi Sasaki,Masato Nikaido,Shiro Wada,Tadasu K. Yamada,Ying Cao,Masami Hasegawa,Norihiro Okada,Norihiro Okada +7 more
TL;DR: The data suggest that B. omurai evolved as an ancient independent lineage that diverged much earlier than B. brydei and B. borealis, which were previously believed to be closely related to B. edeni.
