A global coral phylogeny reveals resilience and vulnerability through deep time - Nature
The most recent common ancestor of the stony coral Scleractinia dates to about 460 million years ago and was probably a solitary, heterotrophic and free-living organism.

The #TMHMS25 has just wrapped up!
It’s been four amazing days of stimulating discussions and sharing our science in a wonderfully relaxed and supportive atmosphere.
There was a truly genuine sense of community among all participants, which I really cherish.

Cheers, to the next one! 🌊

How would that affect the issue at general? Are you suggesting that researchers look for a shortcut to amp their pub record? The portrayed case goes against all research ethics. Of course, fixing one issue doesn’t fix all issues, if that is your larger point.

pretty amazing how much money publishers make, how they pay little to zero to their reviewers/editors , and how they do not invest better in ensuring fair, transparent, and quality peer-review .. paying your reviewers/editors, entails pathway to identity check: www.science.org/content/arti...
