What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)

Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**

Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.

Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.

Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.

Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.

Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

TIL ants that farm aphids influence the aphids’ genes in a similar way that we do with cows. Aphid-farming ants prefer and select for red/green polymorphism. (www.nature.com)

From the article:

Ant-attended aphids are known to excrete high-quality honeydew when ants are present. Ant attendance has a negative effect on the growth and reproduction of the attended aphids. Therefore, trade-offs should occur between the quality of honeydew and the growth and fecundity of aphid individuals. Thus, if attending ants prefer the morph excreting a high-quality honeydew, such trade-offs and resulting competitive interactions are expected between the color morphs in M. yomogicola. The morph excreting high-quality honeydew is known to have a lower reproductive rate than the other morphs[9,10]. This fact implies that if the attending ants prefer one morph, this morph is expected to excrete high-quality honeydew. Note that any such difference between morphs leads to the exclusion of the inferior morphs. Surprisingly, nearly all colonies consist of both green and red morphs in the field.

Non-human animals aren't moral agents. This is like basic stuff, c'mon.

Literally in the abstract

In this paper, we do not challenge this claim. Instead, we presuppose its plausibility in order to explore what ethical consequences follow from it.

And further in the introduction

He has argued that, while animals probably lack the sorts of concepts and metacognitive capacities necessary to be held morally responsible for their behaviour, this only excludes them from the possibility of counting as moral agents. There are, however, certain moral motivations that, in his view, may be reasonably thought to fall within the reach of (at least some) animal species, namely, moral emotions such as “sympathy and compassion, kindness, tolerance, and patience, and also their negative counterparts such as anger, indignation, malice, and spite”, as well as “a sense of what is fair and what is not” (Rowlands 2012, 32). If animals do indeed behave on the basis of moral emotions, they should, he argues, be considered moral subjects, even if their lack of sophisticated cognitive capacities prevents us from holding them morally responsible.1

But yes, I am fairly certain that no non-human animals has the mental facilities to be true moral agents. Especially because this is something a significant chunk of humans struggle with, and no animal comes close to us in terms of abstract thinking and that kinda stuff.
