8. What is taxonomy? Explain its importance.

Ans: Taxonomy is the science of classifying, naming, and describing organisms. The term is derived from two Greek words: taxis (arrangement) and nomos (law), meaning the law of arrangement. Taxonomy is important because it helps in organizing the vast diversity of life on Earth into categories, making it easier for scientists to study, understand, and communicate about organisms. It also helps to establish evolutionary relationships among different species.

9. What is Linnaeus’ contribution to taxonomy?

Ans: Carolus Linnaeus is known as the “father of modern taxonomy” for his introduction of the binomial nomenclature system, which gives each species a two-part scientific name consisting of its genus and species. His book Systema Naturae (1735) established a hierarchical classification system, grouping organisms into categories such as kingdom, phylum, class, order, family, genus, and species. His work laid the foundation for the classification system still in use today.

10. What are the main features that distinguish mammals from other animals?

Ans: Mammals are distinguished by several key features:

(i) Presence of hair or fur on the body.

(ii) Mammary glands that produce milk to nourish the young.

(iii) Sweat glands for temperature regulation.

(iv) Warm-blooded (endothermic), maintaining a constant body temperature.

(v) A four-chambered heart with completely separated oxygenated and deoxygenated blood.

(vi) Viviparous (giving birth to live young), except for monotremes.

(vii) A single pair of bones in the lower jaw.

(viii) Non-nucleated red blood cells (in humans, circular).

11. Explain the features of the Hylobatidae family (gibbons).

(ii) They are arboreal, spending most of their time in trees.

(iii) Gibbons do not have a tail.

(v) Their body is covered in fine, woolly hair, with varying colors such as white, gray, or black.

(vi) Gibbons live in small family groups, with a monogamous social structure.

Ans: Primates have several key characteristics:

(i) Prehensile hands and feet: Adapted for grasping tree branches.

(ii) Flat nails on hands and feet, as opposed to claws.

(iii) Large brain size relative to body size, allowing for complex behavior.

(iv) Bipedalism or partial bipedalism in some species, such as humans.

(v) Stereoscopic vision: Forward-facing eyes for depth perception.

(vi) Opposable thumbs in most species, aiding in grasping and manipulation of objects.

(vii) Highly developed social behavior: Complex communication, group living, and parenting.
