50 year anniversary of The Selfish Gene. The book: minor revisions. The zoo building: completely replaced.

It's the 200th anniversary of what many (especially those of us in the Lakes!) consider the first rock #climb - an ascent of #Pillar Rock (classic photo by Abraham bros) #FRCC

It's the first year for about 15 years that I've not been able to lead a walk up Simonside for the solstice, so here's one I took in happier times
The setting sun on the summer solstice lining up with a long hole through a boulder, thought to have been placed in the neolithic

A fine day for a bike loop around Glenfinnan and Ardgour. (Bit of a different bike from the sit-up city bike i hired in leiden a week or so ago)

Rounded off the CBEN & @ehbea.bsky.social conferences in Leiden with a bike ride to the coast, running into some fine floral displays on the way

Great to be at @ehbea2026.bsky.social and to hear so many great talks. Not so clever was missing the abstract deadline so here's the poster I presented here at the CBEN preconference day

Emblematic of arriving at Bluesky? Or just a weak excuse for sharing a weekend photo?

I have a new paper to share - like it or loathe it! Before concluding that cooperation is driven by indirect reciprocity, consider whether a strategy of helping those who help others can spread because every act of help may be costly to the individual but is beneficial to the strategy

So much exciting science going on... Meanwhile, I was watching hundreds of pink-footed geese (if you look closely), barnacle geese, short-eared owls, marsh harrier, long-tailed duck, twite, whooper swans, ruff... at Druridge Bay

Let's use the outpourings of emotion over the felling of the eponymous Sycamore Gap tree to protect our favourite trees. This is my favourite tree, dominating my view. Do you have a tree that's important to you?

No new science, babies or cats yet today but we have had an influx of red admirals in the garden
