ANS 282 - Intro to Taxonomy and Comparitive Anatomy

What is binomial nomenclature?

A unique name for each species based on morphology and anatomy

What is the first word of binomial nomenclature?

The scientific name of the genus

What is the second word of binomial nomenclature?

The scientific name of the species

Why is taxonomy important?

It helps connect organisms to each other which helps with study and research and makes it easier for scientists who speak different language

Who first came up with classifications?

Aristotle

Who is considered the “father of modern taxonomy”?

Carolus Linnaeus

What is taxonomy based off of?

Morphology and biology

Levels of taxonomy?

Domain, kingdom, phylum, class, order, family, genus, species

What are the main classes of animals that we will look at in ANS 282?

Mammalia, reptilia, aves, osteichthyes

What is the respiratory of aves like?

It is one of the most complicated respiratory system because the bones are also involved in respiration so aves have continuous oxygen supply

How does respiration in osteichthyes work?

They pump water over their gills to obtain oxygen

How do mammalia and aves thermoregulate?

They’re homeothermic (they maintain body temperature at a constant level)

How do reptilia and osteichthyes?

They’re poikilotherms (they thermoregulate by water or air temperture)

How do mammalia reproduce?

They’re viviparous (give birth to live fetus and have mammary glands)

How do aves reproduce?

They’re oviparous (young hatch from eggs)

How do reptilia and osteichthyes?

Most are oviparous (young hatch from eggs) but some are viviparous (live birth) or ovovivparous (incubated in an egg than hatch inside the mother and born alive)

What do mammalia, reptilia and aves skeletons have in common?

They are all (or all descended from) tetrapods (4-limbed vertebrates)
