Zoology Flashcards
What is zoology?
Zoology is the science that studies animals, derived from the Greek terms 'zoon' (animal) and 'logos' (speech).
When did zoology begin to develop scientifically?
Zoology has slowly developed over the centuries since prehistory, with the first scientific reflections passed down from Aristotle.
What were some early methods used in zoology?
Early methods included observation of morphological characteristics (shape, color, size) and classification based on anatomical criteria like invertebrates and vertebrates.
What evidence suggests early humans observed animals closely?
Prehistoric rock paintings and sculptures from the Late Paleocene depict animals with details indicating a good understanding of their environment, such as bison molting or mammoth tail skin folds.
How did genetics and cladistics impact zoology?
The development of biology, including genetics and cladistics, offered new techniques and perspectives, though traditional naturalist disciplines initially seemed outdated.
What event helped restore credibility to zoological studies in contemporary times?
The awarding of the Nobel Prize in Physiology or Medicine in 1973 to ethologists Karl von Frisch, Konrad Lorenz, and Nikolaas Tinbergen brought renewed attention and credibility to zoological studies.
What are some specialized fields of zoology based on animal groups?
Specialized fields include entomology (insects), herpetology (reptiles and amphibians), ichthyology (fish), mammalogy (mammals), ophiology (snakes), ornithology (birds), malacology (mollusks), arachnology (arachnids), and carcinology (crustaceans).
What is entomology?
Entomology is the study of insects.
What is herpetology?
Herpetology is the study of reptiles and amphibians.
What is ichthyology?
Ichthyology is the study of fish.
What is mammalogy?
Mammalogy is the study of mammals.
What is ophiology?
Ophiology is the study of snakes.
What is ornithology?
Ornithology is the study of birds.
What is malacology?
Malacology is the study of mollusks.
What is arachnology?
Arachnology is the study of arachnids.
What is carcinology?
Carcinology is the study of crustaceans.
What are some technical specialties within zoology?
Technical specialties include comparative anatomy, animal physiology, genetics and developmental mechanisms, ethology, ecology, evolutionary biology, and systematics.
What does comparative anatomy study?
Comparative anatomy is the study of animal structure.
What does animal physiology encompass?
Animal physiology is a field that includes disciplines such as anatomy and embryology.
What is ethology?
Ethology is the study of animal behavior.
What does ecology study within zoology?
Ecology includes behavioral ecology and evolutionary ecology, among others.
What is evolutionary biology concerned with?
Evolutionary biology studies evolution, population genetics, heredity, reproduction, natural selection, genetic diversity, and ecological constraints.
What are the goals of systematics, cladistics, phylogenetics, and taxonomy?
These fields classify species and groups of living or extinct species, and study the relationships between them.
What is paleontology's role in zoology?
Paleontology helps understand past zoology, including aspects like paleoclimatology.
What are the key characteristics of animals regarding diversity and environment?
Animals exhibit infinite diversity and polymorphism and inhabit all environments, including those with extreme conditions.
Why is a hierarchical classification necessary for animals?
The diversity of animals requires a hierarchical classification system.
What are examples of characteristics used to group animals?
Examples include jointed feet for arthropods and the presence of a shell for mollusks.
What are the basic elements of the biological classification hierarchy?
The basic elements are Kingdom, Phylum, Class, Order, Family, Genus, and Species. Subdivisions like superorder, order, and suborder can also be used.
