Back from 2 weeks at beautiful St Andrews, part of our @ukri.org BBSRC-funded project on developmental system drift in annelids. Thanks to the EDGe team (current and former members) for hosting me.

Back to the Land of Scots 🏴󠁧󠁢󠁳󠁣󠁴󠁿, to continue our BBSRC-funded work on developmental system drift.

A developmental biologist toolkit: eggs, sperm and a microscope. The nice weather is a bonus 😎

UK EvoDevo is happening today!

We'll try to answer the eternal question, which came first the tea cup of the egg? ☕🥚
