DNA is the key to understanding life. In many cases, genes – specific sequences of DNA – are the starting point to develop better medicines, solve crimes, improve crops, manage conservation, and much more. Take giraffes, the tallest animals on Earth. They have a complicated evolutionary history. Scientists are still figuring out how different giraffe populations are related and how many species there are – which will guide efforts to protect them. Biologist Laura Bertola shares what she learned from giraffe DNA.
In this newsletter, we share a selection of articles about how researchers in different fields are using DNA studies. These include: a study that changes everything we knew about the evolutionary history of modern elephants, a DNA recovery technique which could help women bring rapists to justice and a look at how genetically modified mosquitoes could help in the fight against malaria.
