  1. BSC 103: BIOLOGY AND SOCIETY • FRANK MOORE • OBJECTIVES • LOGISTICS

  2. BIOLOGY AND SOCIETYOBJECTIVES • Biology is all around us! • Impacts our personal and professional lives in many ways. • How so?

  3. BIOLOGY ALL AROUND US

  4. McMoRan’s Davy Jones Gas in the Gulf? Discovery, believed to contain at least 1 trillion cubic feet, may reignite exploration interest Press Register, Mobile, AL Sunday, January 17, 2010

  5. McMoRan’s Davy Jones Gas in the Gulf? • “… another whole layer of dead dinosaurs under there.” • Renewable and nonrewable resources Press Register, Mobile, AL Sunday, January 17, 2010

  6. INTRODUCTION TO BIOLOGICAL SCIENCESOBJECTIVES • Our society is immersed in a scientific revolution, largely biological in nature. • Witness breakthroughs in genetics, cellular biology, and neuroscience as well as advances in understanding the environment around us. • Public understanding of the biological sciences and biotechnology is critical to responsible decision-making in our society, both public and private. • Achievement of that understanding takes on a sense of urgency in the face of widespread scientific illiteracy.

  7. BIOLOGY AND SOCIETYOBJECTIVES • Understand how science is done • Judge the reliability of scientific knowledge • Ensure the ethical use of scientific knowledge • Examples • Y Chromosome evolution • Spread of West Nile Virus

  8. Are Men More Evolved Than Women?www.huffingtonpost.com/2010/01/13 • Chimpanzee and human Y chromosomes are remarkably divergent in structure and gene content. Jennifer Hughes et al. 2010. Nature. In Press. • Meaning/implication of headline? The human X (left) and Y chromosomes, magnified about 10,000 times

  9. Men more evolved ? • Chromosome? • Y-Chromosome? • Human genome? Sequenced over decade. What is function of genes?

  10. Men more evolved? Chromosome 7: CFTR Gene [ Cystic Fibrosis Trans-membrane Conductance Regulator Gene]

  11. Men more evolved?Y-Chromosome • How many pairs of human chromosomes? • Why Y-chromosome sex-determining? • Relationship between X and Y chromosome? • Why compare genetic code of chimpanzee and human?

  12. BIOLOGY AND SOCIETYOBJECTIVES • Understand how science is done • Judge the reliability of scientific knowledge • Ensure the ethical use of scientific knowledge • Examples • Y Chromosome evolution • Spread of West Nile Virus

  13. West Nile Virus • Arbovirus: Arthropod-borne virus • Arthropods: Blood-sucking insects (e.g. mosquitoes, ticks)

  14. Spread of West Nile Virus

  15. Migratory Birds and West Nile Virus Migratory birds suspected as important means of dispersing virus to new regions • What kind of statement? • How does science treat this statement? • What is meant be evidence? Data?

  16. “Banded in Japan, killed in the Delta”Clarion LedgerSunday January 20, 2008 Region between the Mississippi and Yazoo rivers is the Yazoo Basin [Delta], one of the most fertile areas in the world. Northern Pintail (Anas acuta) http://www.ducks.ca/resource/general/naturenotes/pintail.html http://soundwaves.usgs.gov/2002/11/fieldwork.html

  17. Migratory Birds and West Nile Virus Migratory birds suspected As means of dispersing virus to new regions: • Birds are the amplifying • host of West Nile virus. • Birds captured during migratory period have WNV antibodies. • Virus has been isolation from birds during the migratory period

  18. Migratory Birds and West Nile Virus If migratory birds are important dispersal agents, then … • Migrating birds must be infectious (i.e., level of viremia sufficient to infect mosquito). • Infectious migrants must display migratory activity.

  19. BIOLOGY AND SOCIETYOBJECTIVES • Understand how science is done • Judge the reliability of scientific knowledge • Ensure the ethical use of scientific knowledge • Examples??
