Welcome to the discussion of US Politics!

Rules:

  1. Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.

Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

Example:

  1. Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
  2. Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
  3. No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
  4. Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
  5. No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

That's all the rules!

Neanderthals weren't a distinct species otherwise we couldn't have interbred with them.

Nah, species do interbreed. That they can't is a myth

Whether some populations breed true "in the wild" defines species. In the real world this is seriously muddy, but that's beside the point.

Some people have argued they were a subspecies instead for this reason. But I didn’t want to get into that because it doesn’t change the overall picture. Whatever you want to call them, they’re far more distinct than human races today. Races aren’t distinct enough to be labeled at any taxonomic level that’s used to describe distinct taxonomic groups within non-human species. This didn’t stop early racist thinkers from trying, but the picture has become clear after more than a century of scientific research on the topic

But yeah the difference between species and subspecies can be a bit fuzzy as well. We used to define species such that they couldn’t interbreed, but then we learned that lots of clearly distinct species can interbreed too.

In some cases, species can be maintained by natural selection rather than reproductive barriers. A classic example is oak trees. Many oak species can easily cross with their close relatives and do so very frequently. However, since each species is adapted to a different ecological niche, the hybrids end up in ecological no-mans land, doing worse than either pure parent in their respective habitats. Because of this, they rarely reach maturity or contribute much to the gene pool, and the species remain distinct.

However, in some very specific environments they can, and this has been very important for oak evolution since it allows entire clusters of species to occasionally share genes, aiding in their evolution. This is thought to be one reason why oaks have adapted to almost every temperate treed environment in North America.
