WGU C737: Evolution

What C737 Evolution Is and Why It Matters

WGU C737, Evolution, is a biology content course that sits inside the university's science teaching programs, most often the Bachelor of Science in Science Education (Secondary Biology) and related endorsement tracks. It is built for future and current science teachers who need a deep, working command of how life on Earth changes over time so they can turn around and teach it with confidence. Rather than a light survey, the course asks you to understand the actual mechanisms of evolution and the evidence that supports them, from the fossil record to molecular data.

Direct answer: To pass C737, master the core mechanisms of evolution (natural selection, genetic drift, gene flow, mutation) and the categories of evidence that support common descent, then practice applying them to unfamiliar scenarios. Use the WGU course materials and pre-assessment as your map, drill the vocabulary until it is automatic, and keep testing yourself on interpretation of data and diagrams until your practice results are consistently strong.

You will typically take this course while pursuing licensure or an endorsement to teach secondary biology, and it matters for two reasons. First, evolution is the organizing theory of all biology, so a shaky grasp here weakens everything else you teach. Second, evolution is a topic many classroom teachers feel underprepared to present clearly and accurately, so the depth you build in C737 pays off directly in front of students. Note that WGU periodically updates its course codes and titles; if your program lists this content as "Evolutionary Biology" or under a different code, the subject matter and study approach described here still apply.

Topics the Evolution Assessment Emphasizes

Based on WGU's public description of its evolution coursework, expect the assessment to concentrate on a coherent set of core areas. Verify the exact objectives against your course of study page, but plan your studying around these themes:

• Mechanisms of evolutionary change — natural selection, genetic drift, gene flow (migration), and mutation, and how each shifts allele frequencies in a population.
• Evidence for evolution — the fossil record, comparative anatomy (homologous and analogous structures), embryology, biogeography, and molecular and genetic data.
• Population and molecular genetics — allele and genotype frequencies, the conditions of genetic equilibrium, and how molecular comparisons reveal relationships.
• Speciation and phylogenetics — how new species arise, reproductive isolation, and reading phylogenetic trees and cladograms.
• Macroevolution and the history of life — patterns of diversification over deep time and the historical and contemporary factors shaping biodiversity.
• Biodiversity and its conservation — why variation matters and how evolutionary thinking informs conservation.

How Hard C737 Is and How Long to Plan For

Difficulty in this course depends heavily on your biology background. If you have recently completed genetics and general biology, the concepts will feel like an organized extension of what you already know. If your science coursework is further behind you, budget more time for the vocabulary and the genetics that underpins population change. Many students report that content-heavy biology courses like this one reward steady, concept-by-concept study more than last-minute cramming, largely because the assessment asks you to apply ideas rather than just recall definitions.

A realistic plan for most working adults is a few focused weeks of consistent effort rather than a single marathon push. Set a target of studying most days for a manageable block, and let the WGU pre-assessment tell you when you are ready. The honest signal for scheduling the exam is simple: your practice performance is consistently strong across every topic area, not just the ones you enjoy. For a broader look at how WGU structures its exams, see WGU's own overview of scheduling and assessments.

A Study Plan Built for Evolution

The most effective preparation for a concept-and-application course uses three proven techniques deliberately: active recall, spaced repetition, and practice testing. Here is how to apply each to this specific material.

• Start with a diagnostic. Read the course objectives, then take the pre-assessment early. Do not treat a low first score as failure; treat it as a heat map showing exactly which mechanisms or evidence categories need attention.
• Build recall around mechanisms, not lists. For each mechanism (selection, drift, gene flow, mutation), close your notes and explain in your own words what it does to allele frequencies and when it dominates. If you cannot explain it out loud, you do not yet know it.
• Space your reviews. Revisit the hardest topics after one day, then a few days, then a week. Spacing beats re-reading the same chapter repeatedly, and it fits the WGU pace of studying around work.
• Practice interpretation, not just terms. Evolution questions often show a phylogenetic tree, a data table, or a scenario and ask what it implies. Deliberately practice reading cladograms and predicting outcomes rather than only memorizing definitions.
• Use quality visuals. Reputable, free resources such as HHMI BioInteractive and UC Berkeley's Understanding Evolution site are strong for the harder concepts. Treat any student-made flashcard sets as a supplement to verify, never as a substitute for the WGU materials.
• Retake the pre-assessment. When you can pass it comfortably and explain why each answer is right, you are ready to schedule.

Because this course lives in the School of Education, the study habits you build here transfer to your other teaching courses. If you are also working through assessment design, the same disciplined approach pays off in D184 Standards-Based Assessment, and the data-interpretation habits you build reading phylogenies carry into any course that asks you to reason from tables and graphs.

Mistakes That Trip Students Up in This Course

• Memorizing definitions without mechanisms. Knowing that "genetic drift is random change" is not enough; the assessment wants you to predict when drift matters (small populations) versus selection.
• Confusing evidence categories. Homologous versus analogous structures, and comparative anatomy versus molecular evidence, get mixed up under time pressure. Sort them cleanly before exam day.
• Misreading phylogenetic trees. Students often assume the tip order implies "more evolved." Practice reading trees by shared ancestry, not left-to-right ranking.
• Skipping the underlying genetics. If allele frequencies and equilibrium conditions are fuzzy, population-level questions become guesswork. Shore this up early.
• Waiting for a perfect score before starting. Some learners over-study familiar topics and avoid weak ones. Let the pre-assessment force you toward your gaps.

Your C737 Exam Readiness Checklist

• Can you explain each mechanism of evolution and predict its effect on allele frequencies?
• Can you distinguish homologous from analogous structures with your own examples?
• Can you list the major categories of evidence for evolution and what each demonstrates?
• Can you read a phylogenetic tree or cladogram and state which species share the most recent common ancestor?
• Can you describe how a new species forms and what reproductive isolation means?
• Can you connect allele-frequency changes to the conditions that disturb genetic equilibrium?
• Can you explain why biodiversity matters and how evolutionary thinking informs conservation?
• Can you consistently pass the WGU pre-assessment across every topic area, not just your strong ones?

C737 Evolution FAQ

Is WGU C737 an OA or a PA?

C737 is a content-knowledge biology course, and courses of this type at WGU are typically completed through an objective assessment (a proctored, exam-style test with question formats such as multiple choice and scenario items). Always confirm the assessment type on your official course of study page, since WGU updates courses over time.

How many competency units is C737 worth?

The competency-unit value is set in WGU's official catalog and program guide, and it can change between catalog editions. Check your program guide or course of study page for the current figure rather than relying on secondhand numbers.

Is C737 hard?

Difficulty is very individual. Students with recent genetics and general biology tend to find it manageable, while those returning to science after a gap should plan extra time for vocabulary and population genetics. Many students report that steady, concept-focused study works better here than cramming.

How long does C737 take to finish?

Because WGU is self-paced, timing depends on your background and weekly study hours. A few weeks of consistent effort is a reasonable target for most learners; use the pre-assessment to decide when you are truly ready rather than a fixed calendar date.

What is the best way to study for the evolution exam?

Lead with the WGU course materials and pre-assessment, then reinforce weak areas using reputable free resources like HHMI BioInteractive and Understanding Evolution. Emphasize active recall of mechanisms and repeated practice interpreting trees and data.
