In the past, bananas would be overripe in two seconds of leaving them there. But my mom and I did a science project. We peeled the banana's half and then left the other half unpeeled. It was supposed to show that the peel kept it safe. But it didn't overripe. It would've done so in the past. But, nowadays, they don't overripe as easily anymore. Did they change the chemicals of a banana or something? 67.215.28.226 (talk) 00:18, 29 November 2022 (UTC)
Despite OP's exaggerated claim ("In the past, bananas would be overripe in two seconds "), it's plausible that consumers got bananas at a different stage of ripening in the past. Modern supermarket chains might prefer to offer under-ripe bananas on their shelves nowadays, which might wrongfully give the impression that they are different from bananas in the past.

WHERE ARE THE NORTH AMERICAN ABELISAURS?!
editWhy haven't we found definitive proof of abelisaurs in North America when we have fossils of saurolophine hadrosaurs and panoplosaurini nodosaurs in South America? CuddleKing1993 (talk) 05:18, 29 November 2022 (UTC)
- Refer: Wikipedia:Reference desk/Archives/Science/2022 November 16 #Why Labocania is an abelisaur. Note: asking in all caps is considered SHOUTING and is more likely to be ignored by volunteer responders on this desk. 136.56.52.157 (talk) 07:20, 29 November 2022 (UTC)
- I will answer you the the exact same way I answered you the last time you asked a similar question. We believe that less than 1% of all animal species have ever even left fossils, and that of that 1%, less than 1% of THOSE will have been found by people. The reason we haven't found ANY specific species of ANYTHING is because "finding any specific species is really rare". References were provided in my prior answer, if you want to read up more on that. --Jayron32 10:06, 29 November 2022 (UTC)
- Perhaps because South America was in Gondwana when they were around and North America was in Laurasia. NadVolum (talk) 14:16, 29 November 2022 (UTC)
