>“As to why plants would need to panic when it rains, strange as it sounds, rain is actually the leading cause of disease spreading between plants,” said University of Western Australia’s Professor Harvey Millar, co-author of the study.

“When a raindrop splashes across a leaf, tiny droplets of water ricochet in all directions. These droplets can contain bacteria, viruses, or fungal spores.”

“The sick leaves can act as a catapult and in turn spread smaller droplets with pathogens to plants several feet away. It is possible that the healthy plants close by want to protect themselves,

What is described in the article doesn't fit the definition of panic.

I'm torn because maybe I wouldn't have read the article without the needless anthropomorphization. Plants are awesome and interesting to me because they're so planty and not animaly.

He makes an interesting point. Some plants have a response to rain triggered by a hormone. To ascribe the term panic to it though might possibly be mischaracterizing the response because of the tendency to anthropomorphize.

Earlier quoted context omitted.

On the other hand, we have many primal and ancient behaviors that can be contextualized on evolutionary timescales so that it can be reasonably said that, yea, a lot of our behaviors have common heritage with even plants.
