#OnThisDay in 1859, Charles Darwin's On the Origin of Species was first published.

Much of the original manuscript was used as scrap paper by Darwin's children. On the back of this painting of a house is an original manuscript page from Origin!

Pedigree = Crane’s foot 🤯
The origin of 'pedigree'. This type of C12 figure (not a family tree but a way of calculating relatedness – the titles of various relatives have not been put in the circles) looked like a crane's foot, thought medieval folk. So 'pied de grue' and hence 'pedigree'. Source in alt.

A glitch in the matrix? No! I have another PhD available on temperature and AMR, this time with @swbiodtp.bsky.social. Join a friendly group (padpadpadpad.netlify.app/about) in Cornwall to do evolutionary ecology, experimental evolution, and combine phenotyping and sequencing. 🧪🦠 #microsky

This post makes me think of when I was desperately trying to finish my thesis and found myself changing the font on my to-do list.

Meet the “squidworm” 🦑🪱

Discovered by WHOI biologist Larry Madin and colleagues, this 4-inch-long animal was just one of roughly 6,000 new species uncovered during the Census of Marine Life, a decade-long global effort involving more than 2,700 scientists to explore and document ocean life.

New book arrived! Looking forward to learning more about the bonkers life of JBS Haldane. I also note that he sports the same hairstyle that is (sadly) traditional among men in my family. Seems like we will have that in common at least!

To truly understand Tinbergen's behaviour here, you have to address four questions, starting with (1) what is the function of him making his own fish food? (2) how did his fish food making evolve... etc, etc
Another fun Morris memory:

Tinbergen was annoyed when grad students bought fish food instead of making their own. To him, it lacked the dignity of labour.

Unfortunately, our invited speaker @colingarroway.bsky.social is stuck in Canada, but on the upside you will get to hear more about the work by Timothée Bonnet, who is taking over his slot, and from Lizy Mittell about her super relevant work on the invisible fraction! You won’t want to miss this!
If you are at #ESEB2025 and you are interested in predicting evolution 🧬📈 - retrospectively and into to the future - then you are in luck! Symposium 42 organised by @joelpick.bsky.social and Lizy Mittell is on today, and S24 by myself and @sevans.bsky.social tomorrow!
What do you think, can we forecast evolution❓

@sevans.bsky.social and I would love to hear your thoughts, so if you are going to #ESEB2025, submit a talk to our symposium (S24: Forecasting evolution in natural populations) and join @colingarroway.bsky.social and Patrik Nosil!

Deadline April 25.

hello to everyone going to #ESEB2025! want to hear about the consequences of age-dependent plasticity in reproducing via sex vs. asex? I will give a talk at 11:15am on Thursday in S15.02. come for the pretty Hydra illustrations, stay for the novel evolutionary insights on facultative sex!
