8/n Big thanks to Bianca for her persistence on rigorous maths, Nicolas for enthusiasm, inspiration and biological reality, Denis for his awesome sim. code, and to John who was patient enough to answer my endless questions, finally resulting in some fruitful ideas!

7/n Overall, this model gives a decomposition of hybrid fitness that (i) has a clear biological interpretation, (ii) corresponds to distances in a fitness landscape model, and (iii) can be estimated from empirical data.

6/n The distance parameters in our model can be translated into QG composite effects, and estimated from hybrid cross data.

5/n High values (red) of r12 can lead to bounded hybrid advantage, heterosis, or ecological isolation. Low values (blue) lead to a characteristic pattern of intrinsic isolation.

4/n One of these parameters, r12, tells us whether parental phenotypes have diverged more or less than would be predicted by a random walk model of evolution. Its value tends to shrink over time due to system drift or complex environmental change.

3/nWe can predict fitness differences between hybrids from only a few measures of the parental phenotypes, corresponding to distances in the fitness landscape; loosely: the fitness of the parents (their distance to the optimum) and the phenotypic distance between the parents: r12

2/n Strikingly, the patterns of hybrid fitness are robust to a wide range of divergence scenarios including divergence with gene flow, system drift, inbreeding, environmental change, and segregating variation.

“The Geometry and Genetics of Hybridization” -- a thread: How much can we learn from patterns of hybrid fitness? Let’s use a fitness landscape models to generate some predictions and see how they depend on the process of divergence (1/n)

"The Geometry and Genetics of Hybridization" Very excited to see what started as my MSc thesis for turn into this, thanks to great supervision by John Welch and collaboration with Bianca De Sanctis, & Denis Roze. thread to follow...

Just contacted the help desk of for the 3rd(!) time, trying to resolve an issue with the shipping of my bike. Price quadrupled at the last step of booking after I already invested time and money in preparing my parcel... Hope they resolve it this time!

New Nature paper out today states very clearly what is needed if governments are serious about limiting global heating to 1.5C, as agreed at Paris. Spoiler: No new fossil fuelled infrastructure, anywhere, ever. From now on. Read thread for details...

From drift to draft: How much do beneficial mutations actually contribute to predictions of Ohta's slightly deleterious model of molecular evolution?

Evolutionary analyses track rapid language change in an Australian Indigenous community: contact does not always favour simplification. A wonderful collaboration between a linguist, community member and evolutionary biologists.

The picture this theory paints, of one sex chromosome urging its bearer to mate with that individual, the other sex chromosome saying "no, that one!", and the autosomes saying "neither!", reminded me of this wonderful passage from WD Hamilton: 10/
