Genetic Linkage

From Doodle Dogs to COVID: On the Meaning of Wild Type

Zeke, shown here retrieving a stick from the surf at Lambert's Cove, Martha's Vineyard, is an aussiedoodle – a cross between an Australian shepherd and a poodle. I did an informal survey there over the course of a week, and estimated that approximately 70 percent of the dogs on the beach harbored poodle genes.

 

Diverse doodles share the trademark tight curly fur, but vary in size, color, head shape, and behavioral and other traits. Several websites list 50+ variations on the poodle hybrid theme, including the bassetoodle, bernedoodle, chipoo, doxiepoo, Irish doodle, poochon, rottle, and shihpoo.

 

Why poodles? The breed evokes such effusive descriptions as "confident yet affectionate, but also active and deceivingly athletic. What's not to like about the dignified and elegant Poodle?" The mixes are deemed highly intelligent, although I can't imagine any of my cats chasing a stick, let alone retrieving it.

 

Perhaps I was witnessing a biased sampling, and the doodles simply have a combination of gene variants that somehow makes them love running in the sand. I watched, transfixed, as a goldendoodle followed a seabird far out into the surf, upsetting the human observers and revealing a superior avian intelligence.

Summer Musings on the Deaf on Martha’s Vineyard and SevenEves

Deafness was normal on Martha's Vineyard in the 1800s
One recent morning, my husband and I hiked down to Great Rock Bight, our favorite spot on Martha’s Vineyard, before anyone else. When I first saw it years ago, I named it the Planet of the Apes beach after the huge rock that juts up a few hundred yards from shore, like Charlton Heston’s view of the remnants of the statue of liberty at the end of that film.

I had with me a sci-fi tome, "Seven Eves" by Neal Stephenson, and a glossy real estate magazine. Because our house is at the lower end of the price range, I like to ogle the spreads of zillion-dollar estates.

So I opened the magazine to "Historic Waterfront Chilmark Home," with a current image of a spectacular house on the left, and a view from 1901 on the right, behind owners Benjamin and Hattie Mayhew. The house was built in 1878 on 6 acres overlooking two big ponds. A mere $5 million.

Benjamin Mayhew was a descendant of Thomas Mayhew Sr, who "bought" the island in 1641, although the Wampanoag tribe of Gay Head and their ancestors had lived there for more than 10,000 years. Benjamin and his brother Jared were deaf, as were both of their parents, an uncle and two aunts, and many others.

I’d forgotten the wonderful story of the deaf community of Martha’s Vineyard, so thought I’d share it here. Read More
