Q & A

What is the main purpose of the tutorial presented by Mikey Buos?

The main purpose of the tutorial is to demystify and clarify how scientific naming, specifically taxonomy and binomial nomenclature, works and why it is used to identify animals such as ants.

Who is credited with establishing the first binomial nomenclature for living things?

Carolus Linnaeus, a Swedish botanist, physician, and zoologist, is credited with establishing the first binomial nomenclature through his publication 'Systema Naturae' in 1735.

What are the major taxonomic levels mentioned in the tutorial?

The major taxonomic levels mentioned are Kingdom, Phylum, Class, Order, Family, Genus, and Species.

How do humans and ants differ in their classification within the Kingdom Animalia?

Humans and ants both belong to the Kingdom Animalia, but they diverge at the Phylum level: humans belong to Chordata (animals with backbones), while ants belong to Arthropoda.

What is the scientific name of a human according to the script?

The scientific name of a human is Homo sapiens.

What is the scientific name of the fire ant mentioned in the tutorial?

The scientific name of the fire ant mentioned is Solenopsis invicta.

What is the significance of the capitalization in scientific names?

The first letter of the genus is always capitalized, while the first letter of the species is always lowercase. This helps distinguish between the genus and species parts of the binomial nomenclature.

Why should scientific names be italicized whenever possible?

Scientific names should be italicized to indicate that they are scientific terms and to differentiate them from common names.

What does the abbreviation 'sp.' stand for and how is it used in classification?

'sp.' stands for 'species' and is used when the actual specific scientific species name cannot or needs not be specified, indicating an unspecified species of a genus.

What is the meaning of the abbreviation 'ssp.' and how is it used?

'ssp.' stands for 'subspecies' and is used to indicate an unspecified subspecies.

Why is the abbreviation 'cf.' used in classification, and what does it imply?

'cf.' is an abbreviation of the Latin word 'confer', meaning 'compare'. It is used to refer a specimen to a known species even though it may not be of that species, indicating that the identification is not confirmed.

What is the main advantage of using scientific names over common names for organisms?

The main advantage of using scientific names is that they provide a standardized nomenclature that avoids confusion and is universally understood, regardless of language or location.

📚 Introduction to Taxonomy and Binomial Nomenclature

This paragraph introduces the tutorial by Mikey Buos, who is also known as ANS, from Canada. The focus is on taxonomy, the science of classification in biology, and binomial nomenclature, the scientific two-part naming system for organisms. The tutorial aims to clarify the process of scientific naming, particularly for ants and other animals. It begins with the historical context of taxonomy, established by Carl Linnaeus in 1735 with his publication 'Systema Naturae'. The main taxonomic levels are outlined, from Kingdom to Species, with a brief mention of subdivisions and superdivisions. The paragraph also explains the classification of humans and ants, highlighting the differences in their taxonomic paths, and introduces the concept of genus and species names in identifying organisms. The scientific names for humans (Homo sapiens) and a specific ant species (Solenopsis invicta) are provided as examples.

🔍 The Importance of Scientific Nomenclature

The second paragraph delves into the significance of using scientific names in the identification of species. It contrasts the potential confusion arising from common names, which can vary by language and even within the same language, with the universality and precision of scientific nomenclature. The paragraph explains that scientific names, often derived from Latin or Greek, are descriptive and can be indicative of the discoverer or the place of discovery. It also covers the conventions of capitalization and italicization in scientific names, as well as the use of abbreviations such as 'sp.' for unspecified species and 'cf.' for species that are similar to a known species but not confirmed. The paragraph concludes by emphasizing the importance of a standardized nomenclature to avoid confusion and ensure clear communication about species across different languages and regions.

Keywords

💡Taxonomy

Taxonomy is the science of classification used in biology to categorize organisms into different groups based on shared characteristics. It is central to the video's theme as it provides the framework for understanding how organisms are named and grouped. In the script, taxonomy is introduced as the practice established by Carolus Linnaeus, highlighting its historical significance and connection to the development of binomial nomenclature.

💡Binomial Nomenclature

Binomial nomenclature refers to the system of naming species of living organisms by giving each a two-part name, consisting of the genus name and the specific epithet. This concept is fundamental to the video as it explains the universal naming convention used for identifying organisms, such as ants and humans, with examples like 'Homo sapiens' and 'Solenopsis invicta'.

💡Carolus Linnaeus

Carolus Linnaeus, also known as Carl Linnaeus, was a Swedish botanist, physician, and zoologist who is the father of modern taxonomy. His work 'Systema Naturae' in 1735 laid the foundation for the binomial nomenclature system, which is a key point in the script that connects to the video's educational purpose of demystifying scientific naming.

💡Kingdom

In biological classification, 'Kingdom' is the highest taxonomic rank, and it is one of the seven major levels mentioned in the script. It is used to classify organisms into broad groups, such as 'Animalia' for both humans and ants, which illustrates the script's point about the shared classification of different organisms.

💡Phylum

Phylum, also known as 'Fila' in the script, is the next major taxonomic rank below kingdom and is used to classify organisms based on more specific characteristics. Humans are classified under 'Chordata' (animals with backbones), while ants belong to 'Arthropoda', showing how phylum helps to differentiate between different groups within the same kingdom.

💡Genus

Genus is a taxonomic rank used to group species that are closely related and share a common ancestor. In the script, the genus is part of the binomial nomenclature, with the first letter always capitalized, such as 'Homo' for humans and 'Solenopsis' for fire ants, indicating its role in the specific identification of species.

💡Species

Species is the most specific taxonomic rank and refers to a group of organisms that can interbreed to produce fertile offspring. The script emphasizes that both the singular and plural form of 'species' is the same, and it is part of the binomial name, as seen with 'Homo sapiens' and 'Solenopsis invicta'.

💡Latin or Greek

Latin and Greek are the classical languages from which many scientific names are derived. The script explains that species names are often based on these languages, providing examples like 'Chromatogaster', which is descriptive and originates from Greek words, showing the etymological significance in scientific naming.

💡Italicization

In the script, it is mentioned that scientific names should be italicized whenever possible, which is a typographical convention to distinguish scientific names from common names and to indicate their special status in biological classification.

💡Abbreviations

Abbreviations such as 'sp.' for species, 'ssp' for subspecies, and 'cf.' for 'confer' are used in the script to indicate unspecified or uncertain taxonomic designations. These abbreviations are important for the video's message about the precision and flexibility of scientific naming in cases of uncertainty.

💡Common Names

Common names are the everyday names used for organisms, which can vary by language and region. The script contrasts common names with scientific names, explaining that the latter provides a universal and unambiguous way to identify species, avoiding confusion that can arise with common names like 'red ants' or 'potato bug'.

Transcripts

hello guys Mikey buos here AKA ANS

Canada bringing you another random but

helpful tutorial this tutorial is about

taxonomy and binomial nomenclature uh

you know the scientific naming of ants

and just basically is uh created to

demystify and clarify exactly how

scientific naming works and uh why we

use scientific names uh to identify ants

and other animals so watch this next

video taxonomy is the practice and

science of classification in biology it

was first established by a Swedish

botanist physician and zoologist named

carolus lenus through a publication

entitled Systema natur in

1735 he was the first to establish a

binomial nomenclature for living things

meaning the scientific two-part names we

now use universally the order of the

major taxonomic levels are Kingdom philm

class order family genus and species

there are also subdivisions and super

divisions however these are the main

Seven Levels involved in the

classification of living things

let's follow the classification of both

humans and ants humans and ants both

belong to the kingdom Animalia but

diverge at their Fila with humans

belonging to Cordata the cordat or

animals with backbones and ants

belonging to arthop the

arthropods proceeding down each level of

classification the nomenclature becomes

more and more specific the final two

levels genus and species create the

organisms scientific name when

identifying or naming a species we see

the genus and species name the

scientific name of a human is homo

sapiens and the scientific name of these

fire ANS is solenopsis

Invicta by the way both the singular and

plural form of the word species is

species there is one species there are

two

species scientific names are often

derived from Latin or Greek and these

names especially species names are often

named after the person who discovered

them or after the place of Discovery or

native location for instance say I were

to discover a new species of braam merx

in my yard I would call it braam merx

buosi or braam merx Toronto

nianis in most cases the Greek or Latin

origins of taxon names are in some way

descriptive for example the genus

chromatog gaster are known for their

uniquely shaped gasters and it just so

happens that the genus name

crematogaster comes from the Greek

kastos meaning hanging and gaster

meaning

belly so also worth noting is that the

first letter of the genus is always

capitalized and the first letter of the

species is always

lowercase also whenever possible the

scientific name should be

italicized other things to not are the

following

abbreviations the SP abbreviation is

used when the actual specific scientific

species name cannot or needs not be

specified for example camponotus SP

means an unspecified species of the

genus

camponotus if you find a camponotus ant

and aren't sure of its exact species and

want to refer to it as something you can

refer to it as camponotus SP

the abbreviation SP is the plural form

and indicates several species so

camponotus SP means two or more species

of the genus

camponotus remember these abbreviations

are not italicized and are always

lowercase

susp or its plural form

sup are abbreviations used to indicate

an unspecified subspecies

a synonymous abbreviation is SSP and

sspp the abbreviation CF is of the Latin

meaning confer or compare to this is

used to refer a specimen to a known

species even though it may not be of

that species it is most often used when

an identification is not confirmed so

for example if you have an ant that

you're pretty sure belongs to the genus

camponotus and are all Almost sure its

species is noorus but not 100% sure you

can refer to it as camponotus CF novor

kenis at least that way it lets everyone

know that it's what you believe the

species is but it hasn't been

confirmed so why do we need to give

scientific names anyway can't we just

give them an official common name well

the problem with that is different

organisms are called different things in

different languages at least with a

standardized nomenclature the name lasus

Niger identifies the single same ant

species whether mentioned in Italy

Brazil us Zimbabwe Thailand or

Transylvania everyone universally

understands with no confusion what

species is being talked about when

saying lacious Niger as opposed to

common black ant

deoir for mik

or orig negro for

instance also even within the same

language there can be confusion with

common names the common name potato bug

for instance can refer to several

animals at least with a scientific name

to identify them there is no confusion

as to which species you're talking about

another example is the name red ants

which can refer to several reddish

colored ant species including some

belonging to the Genera Mera and

solenopsis so there you have it guys

hope you enjoyed this tutorial hope you

found it very helpful and uh now you

know so please take care and uh do

spread the ant love this is ants Canada
