Territoriality and ancestral governance: the case of the Puel Nahuelbuta Mapuche Indigenous Development Area of Chile

"This essay is intended to introduce the Puel Nahuel Development Area as a design method that fosters local autonomy and, at the same time, contributes to the discussion on new alternative imaginaries toward post-patriarchal and post-capitalist social and cultural relations. " "These beliefs test the question of social justice, indigenous social work, and indigenous traditional wisdom. ".

A gene deriving from the ancestral sex chromosomes was lost from the X and retained on the Y chromosome in eutherian mammals

"Abstract Background The mammalian X and Y chromosomes developed from a pair of common autosomes, whose mammalian X and Y chromosomes were found in a pair of ordinary autosomes. Although the X chromosome widely conserved its gene sequence, the Y chromosome lost 93% of the genes it once shared with the X chromosome. In syntenic regions on the X chromosome in marsupials and autosomes in more distant animals, including lizards, PRSSLY was present on the ancestral autosomes but not in eutherian mammals, but the Y in eutherian mammals was retained on the Y, suggesting that PRSSLY was present on the ancestral autosomes but not X chromosome, including lizards. We find expression in a wider range of somatic tissues outside of eutheria, where PRSSLY orthologs are not Y-linked, indicating that PRSSLY has developed a germ-cell-specific function in eutherians. "PRSSLY is the first example of a gene that derives from the mammalian ancestral sex chromosomes that was missing from the X and retained on the Y. ".

Embryo implantation evolved from an ancestral inflammatory attachment reaction

Inflammation is essential for pregnancy and parturition in humans, but inflammation threatens pregnancy's continuation. " The role of inflammation during implantation, we claim, is an ancestral response to the embryo's status as a foreign body. ".

Ancestral genetic diversity associated with the rapid spread of stress-tolerant coral symbionts in response to Holocene climate change

"These thermotolerant groups established themselves within merely u223c6,000 y under the strain of rapid climate change, and they can therefore predict how other coral reefs can react to global warming. " PAG coral corals' thermo tolerance is aided by their symbiosis with Symbiodinium thermophilum. "Our findings show that current-day biodiversity is highly important for future adaptation to climate change for coral reefs and ecosystems in general. ".

An ancestral bacterial division system is widespread in eukaryotic mitochondria

"Plastid division is also reported to be dependent on homologs of these proteins," the ancestral cyanobacterial endosymbiont that gave rise to plastids. In several less well-studied eukaryote protistan lineages, including jakobid and heterogeneous excavates, a mazeote protistan lineages, including jakobid and heterolobosean excavates, a mazemoebozoans, stramenopiles, amoebozoans, a breviate, and an apusomonad, we discuss We find a mitochondrial localization of these proteins in Saccharomyces cerevisiae, for two of these taxa, amoebozoan Dictyostelium purpureum, and the jakobid Andalucia incarcerata. Multiple eukaryotic lineages' discovery of a proteobacterial-like division system in mitochondria of several eukaryotic lineages suggests that it was the ancestral feature of all eukaryotic mitochondria and has been supplied by a host-based method multiple times in distinct eukaryotic lineages.
