BIOL3005: Evolutionary Biology

Semester 1, 2023 [Normal day] - Remote

Evolution is the biological process that has generated the biodiversity on this planet. It explains the common ancestry of all life on earth, why all organisms use the same genetic code, and why major life forms are constrained to a relatively small number of basic body plans such as four limbs in tetrapods. Thus, the principles of evolution and population genetics underpin all biology, including ecology, medicine, and agriculture. In this unit, you will explore the mechanisms that generate evolutionary change across geological and contemporary scales. You will learn how to use DNA sequences to reconstruct the relationships among organisms and to estimate evolutionary timescales. Evolution is an ongoing process, so you will use genetic techniques to discover whether populations are divided into subpopulations. This unit will examine a variety of organisms, including Australian invertebrates, vertebrates, and plants. By completing this unit, you will develop skills in evolutionary thinking, phylogenetic analysis, population genetics, and genomics. You will learn about fundamental aspects of evolution such as adaptation, sexual selection, symbiosis, and the origins of life. You will gain general skills in computer literacy, data management, and data analysis.

Assessment summary

  • Practical short reports and quizzes: Most of the assessment items will be short exercises provided during practical classes.
  • Scientific report: The results of the “bitter tasting ability” practical classes are to be written up as a scientific report, in the form of a journal article. Guidance on formatting and writing this report will be provided in Week 4.
  • Debate talks: Details will be provided in Week 8.
  • Theory examination: The theory examination will comprise a range of short answer and mini essay questions from any area of the lecture or practical programme. Options will be included so that it will not be necessary to answer all questions in the paper. Time allotted for each question is approximately proportional to the number of lectures presented. This assessment is compulsory and failure to attend, attempt, or submit will result in the award of an AF grade. If a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam). The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator

Detailed information for each assessment can be found on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name

Mark range

Description

High distinction

85 - 100

At HD level, a student demonstrates a flair for the subject as well as a detailed and comprehensive understanding of the unit material. A ‘High Distinction’ reflects exceptional achievement and is awarded to a student who demonstrates the ability to apply their subject knowledge and understanding to produce original solutions for novel or highly complex problems and/or comprehensive critical discussions of theoretical concepts.

Distinction

75 - 84

At DI level, a student demonstrates an aptitude for the subject and a well-developed understanding of the unit material. A ‘Distinction’ reflects excellent achievement and is awarded to a student who demonstrates an ability to apply their subject knowledge and understanding of the subject to produce good solutions for challenging problems and/or a reasonably well-developed critical analysis of theoretical concepts.

Credit

65 - 74

At CR level, a student demonstrates a good command and knowledge of the unit material. A ‘Credit’ reflects solid achievement and is awarded to a student who has a broad general understanding of the unit material and can solve routine problems and/or identify and superficially discuss theoretical concepts.

Pass

50 - 64

At PS level, a student demonstrates proficiency in the unit material. A ‘Pass’ reflects satisfactory achievement and is awarded to a student who has threshold knowledge.

Fail

0 - 49

When you don’t meet the learning outcomes of the unit to a satisfactory standard.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

Due to the exceptional circumstances caused by the COVID-19 pandemic, attendance requirements for this unit of study have been amended. Lectures will be delivered online. Students should make every effort to attend and participate in the scheduled practical classes. Penalties will not be applied if circumstances prevent attendance.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.
