Biology 301M - Ecology, Evolution, and Society - Fall 2018

Designed for non-science majors. Introduction to environmental adaptations, diversity of organisms, population growth and limitations, evolution, origin of life, species interactions, community organization and ecosystem function, and human impact on the environment. Three lecture hours and one discussion hour a week for one semester. May not be counted toward a degree in biology.

BIO 301M is part of UT's Core Curriculum, and accordingly,
this course meets standards and objectives of the Texas Higher Education Coordinating Board for Natural Science and Technology. These include the following four areas: Spaceship Earth

·  Critical Thinking Skills: creative thinking, innovation,
inquiry, and analysis, evaluation and synthesis of information.

·  Communication Skills: effective development, interpretation and
expression of ideas through written, oral and visual communication.

·  Empirical and Quantitative Skills: manipulation and analysis of
numerical data or observable facts resulting in informed conclusions.

·  Teamwork: ability to consider different points of view and to
work effectively with others to support a shared purpose or goal.

Each of us quite naturally perceives ourself to be at the center of things, but no one would deny that other events ultimately have their influence, too. Likewise, many people unconsciously place humanity at the exact center of the universe. In this view, the utility of anything is measured by how it can be used by humans. For many, everything has its dollar value. Such anthropocentrism is understandable, but narrow and misguided.


It is a worthwhile exercise to imagine that something else, such as an ant, a lizard, an oak tree, or an HIV virus, is really the focus of the cosmos. From such a perspective, the almighty dollar quickly loses its primacy. Survival (Survival Kit) and reproduction assume a lot more significance. What good are lizards? Indeed, what good are you?!

Philosophy:

We will attempt to teach you the basic ecology and evolution that everyone should know to become better informed citizens of this, our one and only planet, Spaceship Earth -- we will also do our utmost to encourage you to think. Here are links to some of the things we'll cover in discussion sections: You are expected to read all 24 of these. The first eight will be covered on the first exam, the second eight on the second exam and the remaining eight will be covered on the third exam. All 24 will be included on the final exam. Please read "Scientific Methods" as soon as you can, as we will cover this in early discussions and lectures.

Grading and Grades:


Hour Exams:

Thursday, 27th September
Thursday, 1st November
Thursday, 6th December



Final Exam: Saturday, December 15, 7-10 pm



Download Sample First Exam

Download Sample Second Exam

Download Sample Third Exam



Best 2 of the above 3 hour exams will count 20% each (40% total), your performance on problems and attendance and assignments in discussion sections will count for an additional 20%. The comprehensive final exam makes up the other 40% of your letter grade.

These four exams and your performance in discussion sections are your only opportunities to earn your letter grade. UT's "new" plus/minus grading system will be employed.

No "extra" points are available. Your lowest hour exam will be dropped, so you can miss ONE exam (for which you'll be scored a zero).

You will be expected to "know" everything the instructors say in lecture and discussion sections, including pauses and nuances, as well as everything assigned in reading assignments. Exams will be in multiple choice format. Each hour exam will cover about one-third of the class. Everyone must take at least two of the three hour exams plus the comprehensive 3 hour final exam. No "Make Up" exams will be given.

Final Grades are final, carved in stone, and non-negotiable (please don't even bother to question them!). They are a measure of your own phenotype, and not our reponsibility. We expect you to accept your own performance as an integral part of yourself.
