Ancient Splices of Biology: Tracing the Evolution of Insect Sexual Development

September 04, 2019
Sexual determination and differentiation work in myriad ways across the animal kingdom. In vertebrates, like mammals and fish, sexual determination leads to the development of either ovaries or testis. These organs then secrete hormones that go on to govern the sexual development of the rest of the organism’s body. Insects are a completely different beast.

Dark Centers of Chromosomes Reveal Ancient DNA

June 18, 2019
Geneticists exploring the dark heart of the human genome have discovered big chunks of Neanderthal and other ancient DNA. The results open new ways to study both how chromosomes behave during cell division and how they have changed during human evolution.

Different Strokes for Different Fly Folks: Study Links Reproductive Evolution of Hawaiian Flies to Environment

June 12, 2019
In a new study, UC Davis postdoctoral researcher Didem Sarikaya and her colleagues analyzed egg-laying strategies of 65 different Hawaiian Drosophila species and found that egg-laying capacities diverged in response to their unique environments, which directly affected the number of cells involved in each species’ ovarian development.
