Science as a Human Endeavour: Biology in Context
What you must understand
This strand asks you to see biology as a human activity shaped by evidence, collaboration, ethics and society. Know the distinction between science as a body of knowledge and science as a way of knowing. Be able to discuss how a biological idea developed over time through accumulating evidence and peer critique, how new technologies (sequencing, imaging, gene editing) open questions as well as answer them, and how decisions about health, agriculture and conservation involve values alongside data.
Traps that appear in questions
- Confusing a hypothesis with a theory. A theory is a well-supported explanatory framework, not a guess.
- Describing a discovery as the work of one person when the question asks about collaboration or the influence of prior evidence.
- Ignoring social or ethical dimensions when a stem asks how a finding influenced society.
- Overstating certainty: scientific claims are provisional and bounded by available evidence.
- Treating an application as automatically beneficial without weighing risks, access or unintended consequences.
Worked example and rule of thumb
When asked to evaluate a claim, use a three-step frame: (1) What is the evidence and how strong is it? (2) What are the limitations or uncertainties? (3) What social, ethical or economic factors affect how it is used? For instance, a genetic screening program may be scientifically sound yet raise questions about privacy, consent and equitable access. Rule of thumb: separate the evidence question from the values question before writing a judgement.
