Associate Professor Santiago Ramirez Named as a Chancellor's Fellow

January 22, 2020
Associate Professor Santiago Ramirez, Department of Evolution and Ecology, was among the 20th class of Chancellor's Fellows. This marks the 20th anniversary of the program that provides philanthropic support to exceptional early career faculty members.

Can Scents Create New Species? Smells Like Orchid Bee Evolution

January 13, 2020
To attract a mate, male orchid bees collect scents from the environment to create the perfect aroma. In a study appearing in Nature Communications, UC Davis researchers link the evolution of sexual signaling in orchid bees to a gene that’s been shaped by each species’ perfume preferences

Giraffe, Gemsbok Genome Assemblies Add to Map of Life

August 12, 2019
The genomes of wild animals can help us understand how they have adapted to unique situations, give insight into their evolution and help in efforts to protect or restore endangered species. Two examples are recently published chromosome-scale genome assemblies for the Masai giraffe and the gemsbok.

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.

Coast Redwood and Giant Sequoia Mega-Genomes Sequenced

April 23, 2019
Scientists have successfully sequenced the coast redwood and giant sequoia genomes, completing the first major milestone of a five-year project to develop the tools necessary to study these forests’ genomic diversity.

The Language of Biology: How the Heck Do Scientists Assemble a Genome?

March 14, 2019
The genome—the complete suite of an organism’s DNA and genes—is likened to a blueprint for life. On the surface, this comparison provides some understanding of a biological concept. But according to some scientists, it misses the mark.

Fly Genomes Provide Clues to Parallel Evolution

November 27, 2017
In a paper appearing in PLOS Genetics, Professor David Begun, Department of Evolution and Ecology in the UC Davis College of Biological Sciences, compared the genomes of different fly species to understand how genes—both within and between species—evolve adaptively. He found that two fly species that diverged from a common ancestor some 50 million years ago, exhibited parallel evolution on both short- and long-term timescales.
