Chapter 1 • What is Zoology? • Zoology is the study of animals. It has many sub disciplines and is a very broad field. • Think of how many animals there are out there.
Sub disciplines • Anatomy- Study of structure and parts • Cytology- Study of structure and function of cells. • Ecology-Study of interactions of organism with its environment. • Embryology- Study of development of an organism • Genetics- Study of transmission of traits from parents to offspring. • Histology- Study of tissues • Molecular biology- Study of subcellular details.
Continued • Parasitology- Study of animals that live in or on organisms. • Physiology- Study of the function of animals and their parts • Systematics- Study of classification of, and evolutionary interrelationships among animal groups.
Evolutionary Process • Organic evolution? • It is the change in the genetic makeup of populations of organisms over time. • It is the source of animal diversity. • What is diversity? How does diversity in animal groups relate to human diversity?
Animal classification and evolutionary relationships • Evolution explains why animals appear and why they have a certain function. • It also explains family relationships in animal groups. • Groups of individuals are more closely related if they share more genetic material or DNA.
When some of these bees escaped quarantine in 1957, they began breeding with local Brazilian honey bees, quickly multiplying and extended their range throughout South and Central America at a rate greater than 200 miles per year. In the past decade, AHB began invading North America.
Africanized bees acquired the name killer bees because they will viciously attack people and animals who unwittingly stray into their territory, often resulting in serious injury or death. • It is not necessary to disturb the hive itself to initiate an AHB attack. In fact, Africanized bees have been know to respond viciously to mundane occurrences, including noises or even vibrations from vehicles, equipment and pedestrians.
Though their venom is no more potent than native honey bees, Africanized bees attack in far greater numbers and pursue perceived enemies for greater distances. Once disturbed, colonies may remain agitated for 24 hours, attacking people and animals within a range of a quarter mile from the hive.
On July 15, 1993, 82-year-old Lino Lopez became the first person to die in the U.S. from Africanized honey bee stings. He was stung more than 40 times while trying to remove a colony from a wall in an abandoned building on his ranch near Harlingen, Texas.
Arizona's first human fatality from Africanized Bees occurred in October, 1993 when 88-year-old Apache Junction woman disturbed a large Africanized honey bee colony in an abandoned building on her property and was stung numerous times.
Swarm more often than European honey bees • Do not have stronger venom than the European honey bee • Each bee can only sting one time – females die after stinging • Eat nectar and pollen and make honey • Are not native to the U.S.; they came from Africa
Hybrid species • A wolphin is a rare hybrid formed from a cross between a bottlenose dolphin and a false killer whale. There are currently only two in captivity at the Sea Life Park in Hawaii. A wolphin’s size, colour and shape are intermediate between the parent species. The first captive wolphin was Kekaimalu, which shows mixed heritage even in its teeth: bottlenose dolphins have 88, false killer whales have 44 and Kekaimalu has 66!
