Skeletons in the closet: my ancestry DNA story

Are you sitting down?’ the ominous words came down the phone line. Usually, that means something less than happy is about to be imparted. ‘It’s about your grandparents ….

I grew up in the sunshine capital of Aotearoa New Zealand. My maternal grandparents lived just down the road. My grandfather was always a big part of my life. When not working in his immaculate garden that had featured on Maggie Barry’s Garden Show, he would be pottering around ours. ‘Escaping Grandma’, he would joke. In his workshop (one that would put Father Christmas to shame), he built us the wooden toys my own kids still play with and helped me refurbish my centreboard yacht. Grandpa’s steamed fruit pudding was always a firm favourite and something we, as his grandchildren, have been trying to recreate ever since. He was the best grandfather a kid could have, and the type of grandpa I want for my kids, especially given my own Dad’s early death when I was thirteen.

‘Honey, I’m related to Genghis Khan’: the hype around ancestral DNA testing

Television documentaries focusing on the use of ancestral DNA to reveal hidden mysteries in family trees are becoming increasingly popular. However, in our house they are known as ‘the time Daddy rants at the TV’.

Quite frequently, you will hear me exclaim to my kids ‘You can’t say that!’ or ‘There’s no evidence to support that’, before I throw my hands up in exasperation. Despite the genomic revolution having swept through science and the popularity of testing for ancestral DNA, there is still a lot of hype and misconception surrounding the field. So, what is the hype and should we be concerned? Continue reading “‘Honey, I’m related to Genghis Khan’: the hype around ancestral DNA testing”

Hiding in plain sight: how we found New Zealand’s newest seabird, the Kōhatu Shag

New Zealand was once a land of birds. A bustling and cosmopolitan metropolis of different species that had evolved in isolation until the arrival of humans. Scientists thought we knew the characters that made up this enigmatic ecosystem of a time long past, but we were wrong.

Hiding in plain sight, in fossil deposits throughout Northland, and natural history collections, was an entirely new species of seabird, the Kōhatu Shag, albeit sadly extinct. This research has just been published in Molecular Phylogenetics and Evolution and included collaborators from the Otago Palaeogenetics Laboratory (University of Otago), Arizona State University, Birds New Zealand, Auckland Museum, Canterbury Museum and the Museum of New Zealand Te Papa Tongarewa.
