Abstract In this study, we successfully extracted ancient DNA from skeletal remains of the Japanese sea lion—a species that is practically extinct—from archaeological sites and determined a partial sequence of its mitochondrial DNA control region. A molecular phylogenetic tree constructed by the neighbor-joining (NJ) method showed that the sequences from Japanese sea lions clustered together, with a high bootstrap value, and that this cluster was closest to the California sea lion cluster. The…

The First Molecular Evidence of Korean Zalophus japonicus (Otariidae: Sea Lions) from the Archaeological Site of Dokdo Island, Korea
TLDR
The mitochondrial sequence was clearly distinct from two other sea lions, Z. californianus and Z. wollebaeki, and could provide useful information for species identification and genetic diversity of Z. japonicus.
The complete mitochondrial genome of Japanese sea lion, Zalophus japonicus (Carnivora: Otariidae) analyzed using the excavated skeletal remains from Ulleungdo, South Korea
TLDR
Phylogenetic analysis showed that Z. japonicus was a sister species to Z. californianus with 98.61% nucleotide sequence identity among 11 pinniped species in the infraorder Pinnipedia, which supported the previous results.
Galápagos and Californian sea lions are separate species: Genetic analysis of the genus Zalophus and its implications for conservation management
TLDR
A case is built for classifying the Galápagos sea lion, the Californian sea lion and the Japanese sea lion as true species using a set of different phylogenetic reconstruction approaches.
The monophyletic origin of sea lions and fur seals (Carnivora; Otariidae) in the Southern Hemisphere.
TLDR
A novel evolutionary and dispersal scenario of otariids is proposed based on this phylogenetic hypothesis, estimated divergence times, and fossil records, and according to the results, the center of origin of the southern otariid is hypothesized to be the eastern South Pacific along the west coast of South America.
California, Galapagos, and Japanese Sea Lions: Zalophus californianus, Z. wollebaeki, and Z. japonicus
This chapter discusses the characteristics, taxonomy, distribution, abundance, and ecology of California, Galapagos, and Japanese sea lions. These are closely related species that together comprise…
Pinniped taxonomy: review of currently recognized species and subspecies, and evidence used for their description
TLDR
Morphologic and genetic criteria used to recognize pinniped species and subspecies are evaluated individually for all taxa in the three families: Otariidae (sea lions and fur seals), Odobenidae (walruses) and Phocidae (seals).
HISTORICAL POPULATION GENETICS OF CALLORHINUS URSINUS (NORTHERN FUR SEALS) FROM THE ALEUTIAN ISLANDS
TLDR
This chapter discusses how to identify the different types of fruit trees based on their fruit-like properties and some of the strategies used to identify them.

Ancient DNA Analysis of Brown Bear (Ursus arctos) Remains from the Archeological Site of Rebun Island, Hokkaido, Japan
TLDR
It is demonstrated that juvenile ancient bears of Rebun Island were originated from southern Hokkaido, which was an outside area of the Okhotsk Culture and belonged to the Epi-Jomon Culture with a close relation to a northern part of the Tohoku district.
Fur seals and sea lions (Otariidae): Identification of species and taxonomic review
TLDR
Recent re‐examination of the genetic basis of taxonomic diversity within otariids required matching by comprehensive new studies of skull morphometry based on large sample sizes, to provide a sound basis for re‐appraisal of species limits in the family.
Nucleotide Substitution Rate of Mammalian Mitochondrial Genomes
TLDR
This study examines the evolutionary pattern of the different functional mtDNA regions as accurately as possible on the grounds of available data, revealing some important ``genomic laws.
Seals, Sea Lions, and Walruses: A Review of the Pinnipedia
TLDR
The pinnipeds, as a group, are world-wide in distribution although they are limited essentially to continental shores, islands, and polar ice fields in the breeding season, therefore, their distribution is essentially one-dimensional, comparable to that of alcids among birds, certain fishes and many marine invertebrates.
Molecular Evolutionary Genetics
TLDR
Recent developments of statistical methods in molecular phylogenetics are reviewed and it is shown that the mathematical foundations of these methods are not well established, but computer simulations and empirical data indicate that currently used methods produce reasonably good phylogenetic trees when a sufficiently large number of nucleotides or amino acids are used.
The neighbor-joining method: a new method for reconstructing phylogenetic trees.
TLDR
The neighbor-joining method and Sattath and Tversky's method are shown to be generally better than the other methods for reconstructing phylogenetic trees from evolutionary distance data.
Mitochondrial DNA from Ancient Bones
TLDR
The discovery that DNA can also be recovered from ancient hones has created new possibilities for the study of past populations, as bones are abundant archaeological remains and many museums throughout the world contain extensive and well-characterized osteological collections.
A simple method for estimating evolutionary rates of base substitutions through comparative studies of nucleotide sequences
  • M. Kimura
  • Biology, Medicine
    Journal of Molecular Evolution
  • 2005
TLDR
Some examples were worked out using reported globin sequences to show that synonymous substitutions occur at much higher rates than amino acid-altering substitutions in evolution.
CONFIDENCE LIMITS ON PHYLOGENIES: AN APPROACH USING THE BOOTSTRAP
  • J. Felsenstein
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1985
TLDR
The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters.
Molecular Cloning: A Laboratory Manual
