We are pleased to announce that David Kingsley, PhD is the 2017 recipient of the GSA Medal for outstanding contributions to the field of genetics in the past 15 years. His experimental work has shifted paradigms about how the physical traits of vertebrate organisms evolve. Kingsley is a Professor and Howard Hughes Medical Institute Investigator…

When geneticist Rob Unckless took his son to Lego Club at the local library, he was not expecting to start a new collaboration. The result is the striking piece of science-inspired art that graces the cover of the February issue of GENETICS. Created by artist Kent Smith, “Attack of the 50 Foot Mosquito” was inspired…

Despite being covered by a massive, permanent ice sheet, Greenland has been continuously inhabited by humans for over a thousand years. Most modern Greenlanders are Inuit whose ancestors migrated eastward from Canada around 1000 AD, bringing technology like kayaks and dogsleds. They eventually settled on the coasts of the world’s largest island, hunting whales and…

Recombination within the genome isn’t random. This swapping of DNA segments between one chromosome and its homolog preferentially affects specific genome regions called hotspots. These regions can have recombination rates many times higher than other areas of the genome, and the rapid shuffling of genetic information is thought to be important in evolution. The location…

Sex chromosomes have evolved from autosomes hundreds of times across the tree of life. In mammals, sex is controlled by the Y chromosome-linked gene SRY, which triggers the development of male anatomy. Sex determination in most mammals is extremely conserved; essentially all marsupials and placental mammals share the same pair of X and Y chromosomes…

Like any revolutionary technology, domestic horses changed human society. The incredible speed and strength of these animals opened up new opportunities to spread trade, language, and culture. For thousands of years, horses have been helping build human society by pulling wagons and plows and carrying soldiers and travelers on their backs. Horse husbandry changed humanity,…

According to a survey from the Pew Research Center, 33% of Americans believe that God created humans in their present form within the last 10,000 years and another 24% believe that God guided evolution over millions of years to create humans as they exist today. While scientists should respect people’s deeply held religious beliefs, it…

A genomic analysis of 28 dog breeds has traced the genetic history of the remarkable Fonni’s Dog, a herd guardian endemic to the Mediterranean island of Sardinia. The results, published in this month’s issue of GENETICS, reveal that the regional variety has developed into a true breed through unregulated selection for its distinctive behavior, and that…

The beautiful cover of the August issue of GENETICS was created by artist Michele Banks to commemorate the fiftieth anniversary of a pivotal moment in the history of evolutionary biology: the 1966 publication of a pair of GENETICS papers using protein electrophoresis to reveal that natural genetic diversity is bountiful. Thanks to a conversation between…

Geography and ecology are key factors that have influenced the genetic makeup of human groups in southern Africa, according to new research discussed in the journal GENETICS, a publication of the Genetics Society of America. By investigating the ancestries of twenty-two KhoeSan groups, including new samples from the Nama and the ≠Khomani, researchers conclude that…

Guest post by Caroline Berger. #TAGC16 Shorts are brief summaries of presentations at The Allied Genetics Conference, a combined meeting of seven genetics research communities held July 13-17, 2016 in Orlando, Florida. You might remember the flickering cilia of little Paramecia  from the classroom, where these ciliate species can be easily observed with a binocular…
