Master the Turducken! mhlo.co Mahalo biology expert Mary Poffenroth explains the classification system of species and the taxonomic hierarchy. The Taxonomic Hierarchy ——————————————————————— In biological taxonomy, all life kinds can be classified inside a hierarchal program that orders them from the broadest, most inclusive categories to the narrowest, most unique. The most extensively used typical categories are domain, kingdom, phylum, class, order, loved ones, genus and species.www.biology-on the internet.org This taxonomic system was at first pioneered by Carl Linnaeus in the 18th century. Linnaeus employed Latin terms to arrange species according to observable similarities and variations in their physical morphology. With current innovations in molecular biology, the conventional classification technique has been produced more precise by the chance of going past superficial similarities and mapping similarities and variations amongst species at the genetic degree. Following this hierarchy, the highest degree, domain, distinguishes among bacteria and organisms with a true cell nucleus. The next level down, kingdom, distinguishes plants from animals. Below the kingdom degree, at the degree of phylum, we can differentiate amongst vertebrates and creatures with no backbone. Among the vertebrates, you can differentiate mammals from birds, fish and reptiles at the class level. Among mammals, you can differentiate among ones that eat meat …

@Theconservativemama i thought that’s that you tube was for… We own this site mama!
@hallnoats4ever what is the point of your disgusting comment? Can’t you find some other venue to vent your frustrations? I feel sorry for you!
Great Explanations!
i like your videos simple to understand:)
the way i remember the classifications is;
kids playing chasey on freeway get squahsed:)
hi…. i wanna be a member. let me join in this page. i’ll take some video to support biology learning of my student. will you let me? thanks before
mahaolo really is useful
My biology teacher said “dumb kids play chess on freeway get slaughtered” haha
Thank you!

Many viruses, if you could consider them life, use RNA rather than DNA. But then again, one of the requirements we subjectively call something that is alive is that they have DNA. So if it doesn’t have DNA, than it’s by definition, not alive. But again, this is subjective, so feel free to call it what you want to until a more objective scientific consensus is made.

Dear Professor Poffenroth:
All organisms have DNA. How this happened? A common person like me would think that nature tried many possibilities or solutions, not only DNA based. Whatever the case was, DNA organisms became a very good solution and exploded in many variations that evolved to present species, but at least some other forms would have survived or even evolved. What then? Only DNA based organisms appeared ever, or other forms existed, but were eaten by “us” ?
hmmm. iv have only lernt 6 words to do with classifacation but domain sorta gets me my sciens techer did not tell up adout domain? odd but i like biology its fun
my acronym: don’t kiss prince charming only for good stories ;3

“Virus classification is the process of naming viruses and placing them into a taxonomic system. Similar to the classification systems used for cellular organisms, virus classification is the subject of ongoing debate and proposals. This is mainly due to the pseudo-living nature of viruses, which are not yet definitively classified as living or non-living. As such, they do not fit neatly into the established biological classification system in place for cellular organisms.”
where the viruses fit? I mean what domain: bacteria, archea, eukarya ?
Thanks for this! It’s great for my lesson plan!
GREAT VIDEO!
