The polar bear (Ursus maritimus) and their close relatives the brown bear (Ursus arctos horribilis) were thought to have diverged from a common ancestor around 150-200,000 years ago, an estimate based on DNA sequences from mitochondria (small structures which are the ‘energy powerhouses’ within our cells and contain some genes that are independent from those found in the nucleus). However, researchers have recently examined genetic markers from the nuclear DNA of polar and brown bears and found a whole different story. The study has revealed that polar bears actually diverged around 600,000 years ago - giving them a much longer period than was previously thought to evolve their unique adaptations to Arctic conditions. This makes sense, as the previous estimate would have meant the polar bears had evolved their adaptations at a rate that would be exceptionally rapid for a large mammal. The false story told by the mitochondrial DNA is likely to be due to hybridisation between polar and brown bears that has occurred since the species diverged (see previous post). Mitochondrial DNA is inherited from the mother, so it is likely that along the way, polar bears may have picked up mitochondrial DNA from a brown bear mother which is now mixed with genetic sequences typical of the polar bear. DNA in the nucleus, however, has been less affected by hybridisation.
The genetic analysis also flagged up much lower genetic diversity across polar bears than is seen in brown bears. This is a common feature in endangered species. The reason is often that the species has faced difficult environmental pressures in the past, leading to large reductions in population size, then followed by inbreeding between related individuals in order for the species to recover. A lack of genetic diversity will make it all the more difficult for polar bears to survive the pressures they currently face, such as climatic warming, human interference, and pollution in their food chain. If one individual struggles to cope, and all individuals are genetically similar, then it is certain that many others will also lack the features needed to survive and prosper through these difficult times. You can help support the polar bear by becoming a member or adopting an animal through WWF.

I got asked for this recipe, and I really think that every single one of you (who eats shellfish and other animals) should make this, like, right now - so - here it is.
It’s modified from a recipe in the magazine Cooking Light “Favorite Comfort Food Recipes”, January 6, 2012. And every time I make it, I think of more modifications - this last time I figured out I should make a broth using the shrimp shells. And now as I’ve just gone through it, I think this could probably be delicious with some lemon squirted on it after it’s plated. Anyway - this is the serious bomb.
The recipe says it yields 4 servings, but I think it’s more like 6 or 7.
Serve over grits.
SHRIMP AND OKRA GUMBO
Ingredients:
- Shells from the shrimp, reserved
- 1 C water
- 3 tbsp canola oil
- 3 tbsp AP flour
- 1 C shrimp broth
- 1 C chopped onion
- 2 andouille sausages (@ 6 or 7 ozs)
- 2/3 cup celery sliced 1/4” on the diagonal
- 1 tsp dried thyme
- 3 garlic cloves, minced
- 1/2 lb fresh okra pods, sliced 1/4”
- 1/4 C water
- 1 tsp ground red pepper (I recommend pasilla, but any will do)
- 1 tsp paprika
- 1 tsp fresh ground black pepper
- 1/4 tsp salt
- 1/4 tsp ground allspice
- 1 (28 oz) can diced tomatoes (I use fire-roasted)
- 1 lb peeled, deveined large shrimp (pink, not farmed is best)(don’t buy pre-cooked!!!)
- 2 tbsp chopped fresh flat-leaf parsley
Cook:
- Boil shrimp shells in 1 C water for at least 20 mins, up to 30. You’ll need this broth at the end of step 2, so start this early, and chop all your veggies and stuff while it’s boiling.
- Heat 2 tbsp oil in the largest pan you have (this is the pan you’ll use through all stages, and it needs to accommodate the entire meal). Add flour and whisk around for at least 5 mins, up to 10, until browned slightly and the flour is cooked (raw flour taste is so gross). Add broth and continue to stir until smoothly incorporated and the sauce is thick. Pour into a bowl and set aside. Wipe pan out with paper towel.
- Heat remaining 1 tbsp oil in pan over medium heat. Add onion and sausage and cook 7 minutes, stirring occasionally.
- Add bell pepper and next 4 ingredients (through okra); cook 5 minutes or until vegetables are almost tender, stirring occasionally.
- Add shrimp broth sauce, water, and next 6 ingredients (through tomatoes). Bring to a boil; reduce heat, and simmer 10-20 mins, just until vegetables are tender and sauce is thickened.
- Stir in shrimp; cook 4 minutes or until done, flipping them half-way.
- Serve over grits and sprinkle with parsley. Maybe squeeze some lemon on there.
this is so freaking tantalizing!!!!
