Evolutionary geneticist. I think about evolution across timescales and constraints on it from interactions at each scale. I use both population and quantitative genetics to do science. I love music, writing, and my cats (order varies on a daily basis).
Across cohorts, mean AFR changed differently across populations.
And when we looked at breeding values, there was no consistent genetic trend either.
(See figure — phenotypic vs. genetic patterns across time.)

Our focal trait: age at first reproduction (AFR).
Linear models show strong directional selection favoring earlier AFR (see figure 👇).
Quantitative genetic models confirm that AFR is heritable (h² ≈ 0.11).
Yet—things get interesting.

It's been a while since I've posted on this app! To commemorate restarting my posting activity, here's a cute eye bleach content courtesy of our feline twins.

Our boy with another banger sleeping position. He looks like he is ready to kitty launch!

Currently my cat is exploring some very acute angles for his spine during sleep position. All I can say is that if you have the spine for it, go for it!

I am documenting the absolutely remarkable contortionist-like sleeping position of my cat. I am jealous!
