Feels like this paper on protein-templated DNA synthesis by a natural enzyme warrants some comment.
So here's a 🧵. /1

One of biggest mysteries in biology: how did complex eukaryotic cells evolve from simple microbes? ~1.8 billion years ago, an archaeal cell likely merged with a bacterium to form the first eukaryotic cell, but can we ever find direct evidence of this transformative event? 🦠 🚶‍♂️

Did you know that Evolution Letters now publishes reviews?! Our inaugural one is fantastic! Deep learning is opening new doors for evolutionary genomics, especially for nonmodel organisms with sparse or uncertain genomic data. doi.org/10.1093/evle...

Um pássaro pequeno de coloração predominantemente marrom e preta repousa sobre um tronco coberto de musgo verde vibrante. Sua cabeça e nuca exibem um padrão intricado de manchas cinzentas e marrons, enquanto as costas e as asas são marrons com pequenas pintas amareladas. O peito é escuro, quase preto, contrastando com a barriga mais clara. Suas pernas finas e azuladas seguram firmemente o tronco, e o bico fino e alongado aponta para a direita. O olhar atento do pássaro sugere vigilância. O fundo é um borrão suave de tons verdes e marrons, indicando uma vegetação densa.

Well, it's official. After our paper last year (onlinelibrary.wiley.com/doi/full/10....), the Slender-billed Curlew is officially declared Extinct today.

Scientists dream of describing new species, not writing their obituary and epitaph, knowing that they are gone forever #ornithology
