Aug. 18, 2022 Two novel hypotheses have been proposed that address the 'two-fold cost of sex': one of the biggest enigmas in the evolution of sexual ...
July 14, 2021 For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has visited the Sagami River to collect algal samples to understand how living things evolved different sexes. The threes sexes ...
Sep. 2, 2021 The cichlids of Lake Tanganyika in Africa are highly diverse -- including with regard to sex chromosomes. These have changed extremely frequently in the course of the evolution of these fish and, ...
July 29, 2021 New research finds that sexual reproduction and multicellularity drive diversity among different ...
Nov. 2, 2023 Researchers have shown that sex differences in animals vary dramatically across species, organs and developmental stages, and evolve quickly at the gene level but slowly at the cell type ...
Apr. 15, 2021 Bearded dragon embryos can use two different sets of genes to become a female lizard -- one activated by the sex chromosomes and the other activated by high temperatures during development, ...
Oct. 14, 2021 Hot desert sex has resulted in major genetic differences between male and female jojoba plants -- one of only 6 percent of plants that require a male and female plant to reproduce. New research ...
Feb. 24, 2022 Stick insects that reproduce asexually cannot adapt as quickly in the course of evolution as sexually reproducing species, leading to a decrease in biological diversity, according to new ...
Oct. 4, 2023 To date it has been unclear exactly how the sex of a bee is determined. A research team comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. ...
Sep. 9, 2022 Scientists have known that sex-determination in vertebrates happens in the germ cells, a body's reproductive cells, and the somatic cells, the cells that are not reproductive cells. Yet they ...
