Nomenclatura Binominal
الملخص
TLDRThe video discusses binomial nomenclature, which is the standardized system for naming species in biology. It outlines the historical background of the classification system, introducing notable figures such as Aristotle and Carl Linnaeus. The key rules involve using Latin for the names, which are composed of two parts: the genus and species. Each name must be italicized or underlined, with the genus capitalized and the species in lowercase. Examples such as 'Panthera onca' for the jaguar and 'Homo sapiens' for humans illustrate these rules. The video also briefly covers trinomial nomenclature, where a subspecies is identified, and mentions the importance of naming priority in scientific descriptions.

The speaker shares the classification of humans, outlining the taxonomy from kingdom (Animalia) through phylum (Chordata), class (Mammalia), order (Primates), family (Hominidae), genus (Homo), to species (Homo sapiens). The discussion includes examples of trinomial nomenclature for subspecies like 'Rhea americana' and illustrates how to format scientific names, mentioning the importance of author's names in naming conventions, while also noting the priority in naming based on who described the species first.

The genus name should be capitalized and italicized, while the species name should be in lowercase and also italicized.
Can binomial nomenclature change over time?
No, Latin as a 'dead' language remains unchanged, ensuring consistency.
What happens if multiple discoveries occur for the same species?
Priority is given to the first validly published name.
What does the suffix vary between animal and plant families?
Animal families typically end with '-idae', while plant families often end with '-aceae'.
Is there a trinomial nomenclature system?
Yes, it can include a subspecies or variety name as a third component.
Who was Carlos Chagas?
Carlos Chagas was a Brazilian physician who discovered the 'Trypanosoma cruzi' parasite.
