Even Darwin was before Genetics. Mendel was just starting his research when Darwin published his magnum opus and Darwin isn't believed to have ever read any of Mendel's findings. Taxonomy is challenging since the relationships first described didn't have anything to do with ancestry but merely with morphology/function. Ancestry has long been a contested question. It will always be challenging to impose a Darwinistic outlook onto that structure. Issues abound: fertility, genetic, morphological, and geographical methods of defining relationships all tend to render different shaped trees. Then there is the issue that convergence isn't merely morphological but also genetic: you can't simply assume relatedness because of similar genes or shape/function. Taxonomy will always be a human imposition onto the world: the content of which will never be unquestionable. But doesn't mean we shouldn't try. Most of the important yet unanswerable questions in life are vital precisely because of the information we gain in the search for a better purchase toward a solution.

The video needed some more thorough research. It is quite surprising that the main "problem" mentioned for DNA barcoding-based species description was the lack of resources or accesibility to some researchers/amateurs. Nothing was mentioned about that DNA barcoding, even if useful in countless situations, is conceptually an oversimplification that leads to incorrect species estimation in many cases, particularly when great speciators are involved. DNA barcoding can speed up some species descriptions but, when it fails (hybridization, incomplete lineage sorting, paralogy, radiations, etc.), correcting the failures may take an enormous amount of resources, both in time and funds. There are no shortcuts when describing species, just to have taxonomists working hard and combining all available data, from more classical morphological descriptions to the state-of-the-art molecular techniques.

Awesome love all your videos

This was a very difficult issue to explain and you did am amazing job. Props to you!

Molecular taxonomy is priceless, but overestimated for systematics on the large scale. Paraphyletic morphological taxa should exist. If some two groups of jellyfishes so ancient that are more different genetically than humans and some worms, still all their ancestors were jellyfishes, it's relatively conservative groups with "slow" evolution and it is fine to keep it in the same rank as some other phyla that evolved more intensively, but have not enough time to change so much genetically. Main purpose of systematics is to made work with biodiversity more sufficient. Molecular methods great to find polyphyly or some hidden close relations, but if to made a system only by genetic differences ignoring morphology (like 95% differences, 90% differences, etc) - it will be unusable for practical purposes. Molecular taxonomy should be fixing morphological, not replacing it. There are some scientists, mostly geneticists, who telling that we don't need morphology as we can sequence DNA now - hate those guys, so wrong.

It is divided because all other placental mammals evolved from "Insectivora" (the oldest group of placental mammals) and some of insectivor lineages are genetically closer to orders that descend from them, not because they not related to other "Insectivora". Also "Insectivora" collected much more random genetic differences (that not change much in them) as they existed much longer than other placental mammals (as dinosaurs were a thing). It works that simple, smthg like 95% instead of 94% and we have one genetically and morphologically monolithic group, that was considered to be an order, to be divided into few orders ignoring morphological differences and displaced into two different superorders or some groups of that rank. Same would be with dinosaurs and birds if someone would sequence dinosaurs. And it is on the every level with every group - always someone descend from someone. So in my opinion paraphyletic taxa is much more natural than what we having here.

Entirely all of genetic based taxonomic categorization or morphological taxonomic categorization is just wrong and undermines the reality of evolutionary relationships between species. Morphological differences won't really help a biologist trying to determine if a live shark is a Caribbean Sharpnose Shark or an Atlantic Sharpnose shark without killing it. And horizontal gene transfer puts a wrench in the idea of a perfect genetic categorization system. For now I agree that genetics should modify and correct the existing taxonomic model and not outright start from scratch. However if someone is able to come up with a better system (i.e. a mixture of genetic relationships, evolutionary metabolism [metabolism in this case being the rate of change], morphology metabolism, and genetic timescales, run through a factorization program to account for horizontal gene transfer) then let it happen. Preferably a system chosen by nature itself as opposed to one made by man. After all that's why the periodic table has withstood the test of time.

You just start to realize everything is a fish but with more steps or less steps? Paralleled steps? genetic river dance.

Chordata minus amniote = fish It's really not as complicated as some people make it. Yes, sharks are more closely related to humans than they are to lampreys. But the "fish" concept still holds some water.

Nice to know how well-recognized the inconsistencies and often weird logic of taxonomy is. I just started learning this stuff and realizing how many weird or contradictory things there are in classifying life. I chalk it up to the fact it's a somewhat arbitrary art, as well as us having a lot more to learn to try to connect the dots on the tree of life.

It is sadly comforting that I am not the only one often confused by taxonomy ;)

Because there is actual observable and very much quantifiable and justifyable data and reason behind the evolutionary pathways of biology. And in animals (which humans are) as well as plants there only exist male, female, both sexes and sexless. We aren't yeasts, so yes, two sexes. Minor abberations aren't something new entirely, or you'd habe to say that people with down syndrome or other chromosomal abberations aren't humans. And gender is a made up meaningnless term.

Animal kingdom: Our taxonomy is so messy... Plants: Hold my root beer... Bacteria: You, guys are funny...

Excellent video. The complexity and obscurity of taxonomy reminds me of psychology which also is as much of art as it is science. Both disciples rely on formal logic and science but also creative intuition as their subject matter is neither strictly immediate nor material and therefore cannot be tested in the classical scientific sense but must deduce probably like a detective would. I salute the efforts of all the trail blazers who describe our world in meaningful ways.

The hard part's not reorganizing it - it's getting it universally accepted. Centuries old beliefs do not die quickly or quietly.

Thank you for the video. Please don't say "less developed" areas or regions. It is the same issue when researchers think societies can be ranked in old school evolutionary terms, an idea going back to early models when explorers thought there is a linear progression from primitiv to advanced societies. The bias therein has continued to this day and carries dangerous connotations about value ascription to certain societies, cultures and people. The measure of "development" is just as complex as evolution and hardly linear, nor relatable in terms of less and more.

Ultimately the names we give things are artificial but the scientific names should give an idea to evolutionary relationships. Many scientific names may be outdated but we should be updating the system and not just trying to scrap it.

Just sounds like your 15. Lol

Life is comprised of varying shades of grey, and we humans like to select one area and say "this section is white, and this other section is black". It's always going to be hard to fully understand the natural world in all of its complexity, and I don't think we ever fully will, but I think, considering how far our understanding has come, we are doing a pretty good job. Not saying we shouldn't work on our cladistics more, but all things considered, it's a darn good way of making sense of the organisms around us.

So, as a programmer the notion of shoehorning a new paradigm into a system coded for the old paradigm is pretty familiar. And from experience - Burn it down, stomp on the ashes. The overhead of trying to hobble along with the old ALWAYS is higher than the transition cost. Make the new system modular and data independent rather than tied to your paradigm. Give species/subspecies a node. That node can have pointers to groups based on physical characteristics, niches, habitats, and genetic ancestry, but the species stands alone so you have the name no matter what is learned later about those relationships. By treating subspecies as an equivalent node you can define them independently and move them as needed as you learn more. So demoting a species to subspecies is just informational rather than changing the node. And you can even link phylogeny to a subspecies if you happen to figure out that kind of linkage or spin off new groups like subsubsubsubspecies if you need to. And by making the groups mere linkages, you can view the listing dynamically by whatever criteria you need. You can generate a tree of life that is exclusive to Australia, or one that focuses on the physical characteristics that are what matters for biological needs or visual identification, all while also allowing for geneticists to move things around to sort out their species ancestry without toppling everything else. That also means you can work with what you have. A gene sample without physical characteristics gets a node and is only linked as well as it can be. Footprints of an extinct animal get their own node and whatever linkages you can establish. And the bug collector can submit physical characteristics without genetic linkages. You will have things orphaned in whatever grouping they don't have data for, but we have that already with piles of things not in the system at all yet. And as you discover more you can modify links, merge nodes, etc. as needed. We live in the digital age. This doesn't need to have the overhead of specialists that have to decide the whole tree for every species. Just create a node for review and let the experts of each field link their parts and allow the system to hold onto what information we do have about species we don't yet have time to link up. Odds are pretty good someone will even create a narrow AI to set proposed linkages for you to save time. Given what a mess cladistics has become, this is going to have to happen eventually, and it's cheaper the sooner you do it. And in this case it would keep a lot from being lost and squash the mindset of system over reality.

"Taxonomy lacks staff and funding to classify all the new species we find" "Global warming is causing species to go extinct" Sounds like this problem is solving itself :P
