Lots of things live on the ocean floor, an area, which until relatively recently, was considered so inhospitable that nothing at all could live there. I’ve seen estimates that we have cataloged only a tiny fraction of life that is with us today. Because the conditions for fossilization are so rare, we probably will never know about the billions of lifeforms that existed in the past but are no longer alive today. By the way, this doesn’t mean they weren’t amazingly successful. No one would say that Henry Ford, Andrew Carnegie, or Cornelius Vanderbilt were not successful just because they are no longer here today. Also, like the aforementioned men, it’s entirely possible that their progeny are alive and well, but we don’t recognize them as that progeny.

We know of the fossilized remains because the dry land on which they are found was, when those animals were alive, at the bottom of a deep sea. The fact that we lost track of them in the strata is because the sea beds of the intervening millennia are mostly the sea bottoms of today.

This post has me motivated to post one myself. Let’s have fun tearing evolution apart and feeding it to the crows :)

And yet we still can’t find a Bigfoot that so many delusional people believe in. I mean, if we can find a living fossil on the ocean floor, you would really think we could find a Bigfoot, if it existed. In other words, this article is proof that Bigfoot does not exist.

Fame retardant suit on when all the Bigfoot believers come after me.

It is nigh impossible to prove a negative................

“A symbiotic relationship between two marine lifeforms has just been discovered”

“It’s also unclear what benefit the crinoids gain from a relationship with coral”

Wouldn’t that make it a parasitic relationship, not symbiotic?

If the crinoids don't gain any benefit, but aren't significantly negatively affected, that would be a commensal relationship.

I'm glad you commented on the author's interpretation of the phrase "symbiotic relationship," as I was going to: there seems to be a common misconception that symbiosis ("symbiotic relationship") implies that both parties benefit. It does not. Symbiosis is any relationship where organisms live in persistent close contact (not necessarily physically attached or touching). A win-win relationship (the author's misinterpretation) is more properly referred to as mutualism.

To summarize the terminology for anyone who's curious: (how organism A is affected / how organism B is affected: name of that subtype of symbiosis)

benefit/benefit: mutualism

benefit/neutral: commensalism

benefit/harmed: parasitism

neutral/neutral: neutralism

neutral/ harmed: amensalism

harmed/harmed: competition

Thanks for the clarification. Interestingly, it seems that mutualism between two lifeforms can be parasitic to a third lifeform, as demonstrated by the mutualism between Democrats and the media, wherein both are then parasitic on American citizens.

Crinoid, epibiont, hexacoral, benthis.... four new words on a Monday morning, I don’t think I can stand it.

great minds...

hehehe

Science is an open subject folder of discovery then long-term update. The science community still doesn’t have settled what gravity or space is yet.

Anyone or group that decides to close and seal a subject folder is a heretic with nefarious intent.

I'm not advocating for the existence of Bigfoot but I don't think the analogy works. Most if not all efforts to look for Bigfoot are very amateurish. Such few expeditions that weren't people just tromping around in the woods have produced some interesting evidence. Nothing anywhere near conclusive but worth exploring. Also making the following assumption and its a big one, that BF is at least a homind. This makes it smarter then a deer and certainly the average bear. Mountain gorillas & giant pandas took 60 years in the near modern era to establish. The giant panda was even in a restricted range and still it took a serious effort to demonstrate its existence. So I am willing to be open minded regarding its existence. My personal opinion (May it be proven wrong!) is its a bear displaying nonstandard behavior.

It would be nice to have the famous line from Hamlet made a littlr real. Where Hanlet suggests that human knowledge is limited: "There are more things in heaven and Earth, Horatio, Than are dreamt of in your philosophy".

Anyway the romantic in me would love BF to be real but it probably isn't !
