The Genome Anthropology Lab studies the dispersal and environmental adaptation of Homo sapiens, with a focus on ancient genomics. The lab explores why sapiens was able to adapt to every kind of environment, including high latitudes, cold regions, and high altitudes, in the short span of about 60,000 years. DNA is extracted from the remains of people who lived in the past, such as the Jomon people, and the base sequences are determined with next-generation sequencers. Using Jomon genome data, the lab aims to clarify the population history of East Eurasia and the way people lived before the start of agriculture.

The Developmental Evolution Lab studies how leaves are formed, including the mechanisms that control their development and their evolution. The above-ground parts of seed plants consist only of leaves and stems, and flowers are also assemblies of organs that are modified leaves. Using Arabidopsis thaliana as its main experimental material, the lab has been the first in the world to identify key groups of genes that control leaf shape and size. With molecular developmental genetics as its core, and also using methods from classical morphology and physiology, the lab works with a wide variety of plants, including non-model plants from Borneo and Thailand and the liverwort Marchantia polymorpha.

The Ohsugi Lab studies the mechanisms of cell division that occur from fertilization through early development in mammals. The fertilized egg formed by the fusion of an egg and a sperm begins development by repeating a special type of division called cleavage. During this period, chromosome segregation and nuclear formation show features unique to mammals that differ from those of other animals. Using mice, the lab examines the mechanisms that underlie totipotency while observing live embryos under a microscope.

The Genetics Lab (Ohtani Lab) studies, at the molecular level, how plants perceive environmental conditions and how they respond to them. Plants are thought to integrate the whole organism by flexibly regulating cell proliferation and differentiation. Aiming to understand these mechanisms as a system, the lab focuses on RNA metabolism and the cell wall. The lab works with materials at various scales, from molecules to whole organisms, and carries out analyses centered on molecular biology and plant physiology.

The Evolutionary Anthropology Lab studies the evolution of human behavior from both theoretical and empirical perspectives. It asks why human behavior differs so greatly from that of other animals, and how natural selection has shaped human behavior. Using methods from mathematical biology and computational approaches, the lab investigates the evolution of social behavior and cultural evolution.

The Morphological Anthropology Lab studies human evolution, as well as variation and adaptation among human populations, based on the shapes of human bones and teeth. In addition to traditional methods, the lab incorporates new approaches such as CT scanning, three-dimensional morphometrics, simulation, and statistical methods. At the same time, the lab places great importance on collecting and organizing human skeletal collections and on carrying out their conservation treatment and description reliably. Graduate students working in macroscopic morphological anthropology can pursue their own research themes without being tied to a fixed topic.

The Human Evolutionary Biomechanics Lab studies why the skeletal and muscular structures of the human body have come to take their present form. From a mechanical perspective, the lab aims to clarify the evolution of motor functions unique to humans, such as upright bipedal locomotion and the ability to grasp objects precisely. The lab mainly uses three-dimensional shape analysis based on CT images, movement analysis using methods such as motion capture, and simulation with musculoskeletal models. The lab is also pursuing research that applies its findings to the prevention and treatment of musculoskeletal diseases.

The Human Genome Diversity Lab studies the evolutionary history of humans through individual and population differences in the human genome (the complete set of genetic information). The genomes of modern humans retain traces of the natural selection, population splits, admixture, and migrations that their ancestors experienced. The lab combines fieldwork, experiments to examine genomic diversity, statistical and mathematical analysis, and computer simulation. It also investigates how genetic differences relate to differences in individual traits such as body build.

The Evolutionary Phylogenetics Lab studies the evolution and systematics of invertebrates, using molluscs such as snails as its main study material. From classical comparative morphology to molecular phylogenetics and analysis of genome structure, the lab seeks to understand animal evolution from many perspectives. Its research covers evolution at many levels, from the early stages of species divergence to the origin of animal phyla. A model in which reversal of left-right asymmetry in snails gives rise to new species through a single gene was published in Nature.

The Hayashi Lab studies why animals sleep, investigating the significance and evolutionary origins of sleep. Human sleep consists of REM sleep, which produces dreams, and non-REM sleep, which is accompanied by slow waves, a characteristic pattern of brain activity. Using mice and nematodes, the lab combines chemogenetic and optogenetic techniques with behavioral experiments, recording of neural activity, and imaging.
