General Course Information
Course Code HLTH SC 3500 Course Evolution and Human Health Coordinating Unit School of Medical Sciences Term Semester 2 Level Undergraduate Location/s North Terrace Campus Units 3 Contact Up to 4 hours per week Assumed Knowledge 6 units of level I Biology, 6 units level II Biomedical or Medical Sciences, Or first year of MBBS program Course Description Evolution impacts on human health in a number of ways and will continue to do so in the future. Evolutionary Medicine is a discipline at the cross section of medical and social sciences. It will introduce a student to the evolutionary origin of human health and disease and their interactions with a rich diversity of cultures through effects of diet, sexual behaviours and spiritual practices on human biological characteristics. Students will learn how forces of evolution (mutations, natural selection, gene flow, inbreeding, drift and assortative mating) operate in human populations and how they are modified by cultural and social practices. We live in a fast changing world which has numerous consequences for health and future biological structure of humans. Application of developing technologies, especially biotechnology and information technology will have a major impact on future human society and brain evolution. Students will learn how to integrate biological and social aspects of modern society into predictions of possible future course of human development.

Required ResourcesThere are no set texts or set readings for this course. At each session lecturers may suggest a paper or a reference that students might choose to read. The course, however, places an emphasis on the ability to search for relevant materials oneself, according to the focus the student wishes to take. That is, this course involves self-directed learning.
If a paper is required for discussion, a lecturer will provide that paper to students in advance of the session in which it is required.
Recommended ResourcesStudents must be familiar with the Barr Smith Library and must be able to use the electronic databases to search for literature.
Online LearningLecture notes will be posted on MyUni, when a lecturer provides these: however, it is not always the case that a guest lecturer will do so.
The MyUni email facility will be used if a message needs to be relayed to the class in between sessions. Students must ensure that they read their university address emails regularly.
Learning & Teaching Activities
Learning & Teaching ModesThis course requires student-directed learning. That is, students must take responsibility in shaping the focus of their work, and in formulating arguments within that work. Lectures and seminars, both with interactive discussion are principal learning and teaching modes. Since the course attempts to integrate knowledge of a number of disciplines, active student participation in lectures and seminars is required. Lectures will integrate knowledge already possessed by students with new approaches to its interpretation as well as to supplement knowledge where it is found to be missing. Seminars will be fully interactive discussions focussing on specific topics, but allowing branching out into topics identified as important during discussions.
Each student will prepare an oral presentation to start a seminar discussion and each student will write an essay on the topic chosen jointly by a student and a course coordinator so that student interests are provided for while the topic fits into the broader scope of course knowledge.
Thus, students who prefer didactic teaching and a regurgitation of facts will possibly find this course unsuitable. Students who do not enjoy writing essays and who prefer an exam should not take this course.
This course has a strong focus on formative feedback. This means that you are actively encouraged to bring pieces of work, including drafts, to the seminars for feedback and direction before submission for summative assessment (i.e. the marking which results in a grade). Students who do not wish to take responsibility for bringing drafts to seminars for feedback before the final submission, may not enjoy this course and may not do well in the summative tasks.
This course is interdisciplinary and the class includes students from different areas and also comprises materials delivered by lecturers from different disciplines. Wherever possible students will be encouraged to work with students from a different degree programme than their own.
This course encourages students to think, debate and challenge taken-for-granted ideas about health care. Students who do not enjoy class participation and who do not like to play with ideas and express them with others, may not find this course suitable.
We treat students as adult learners and active participants in the course. Therefore, they are expected to take responsibility for their work and for what happens in discussions. Students’ views will be heard and where preferences for change are expressed, these will be considered and discussed by the group. The assessment cannot change, but other details around the course can be accommodated and will be where possible. Where things cannot be changed, a respectful explanation will be given.
This course requires reflective learning. That is, students are required to think about how they are developing and how their ideas are changing – or not – as they hear, think, read, the course-related materials. They are required to then articulate an aspect of this reflection, in a written piece.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.The face-to-face contact with the group is only four hours per week. However, students are expected to spend about at least another four hours per week on researching for their written tasks that comprise the assessment. In the past, some students have reported spending more than this amount of time on research and reading and writing. However, four hours would be the minimum time required.

Small Group Discovery ExperienceThere are weekly 2-hour long seminars during which students make 15 mins presentations on topics related to this week’s lectures and then structured discussion follows by dividing the class into three small groups each with a task of addressing a specific question resulting from presentations.
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment Task Assessment Type Weighting Learning Outcome(s) being addressed Oral presentation Summative and formative 10% 1, 5, 10 Mid-semester test Summative and formative 20% 1-4, 8 Essay Summative and formative 30% 1-10 Final examination Summative 30% 1-10
Assessment Related RequirementsStudents must achieve a minimum of 50% (pass) for each of the tasks containing a summative component. Any supplementary assessments will take a form of viva voce examinations.
Assessment DetailEach student will give one presentation. Oral presentations will be given during seminars. Each presentation will last 15 minutes with at least 5 minutes discussion. Understanding of the material presented and ability to interpret and discuss a specific issue in the context of evolutionary medicine interpretations will be assessed. Students will receive individual feedback from the tutor. Discussion will be structured by assigning students to groups that will either argue for or against the topic of the seminar. Students participating in discussion will be noted. Presentations will be assessed by tutors. Student active participation in seminars will be assessed by taking attendance (50%) and giving marks for quality of the contribution to discussion (50%).
Mid-tem test (1 hour) will comprise short answer questions aimed at testing the knowledge and an essay question testing comprehension and ability to critically discuss relevant topics. An individual feedback will be provided to each student.
Essay will test student’s understanding of a chosen broader area of knowledge included in the course and student’s ability to reason independently and to find relevant information.
Formative feedback will be provided during tutorials for all tasks prior to submission for the summative grade. Please note that seeking formative feedback is the student’s responsibility. As an adult learner, the student must take responsibility for attending tutorials and asking specific questions about their work.
The final written examination will test both knowledge of necessary facts and techniques, and the ability to interpret human variation, its causes and applications.
SubmissionAll essays must be written in a form of a manuscript of a scientific journal article and submitted by a specified deadline at the end of the semester. Late submissions of essays will be penalised. However, please note that the course coordinator welcomes discussion about problems with the submission of work, and extensions can be provided where there are health or personal issues that mean this is necessary. Late work with no explanation prior to late submission will be penalised.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
