Exam-ready in minutes. ✨ Your Term 2 Revision Program for Grade 12 Life Sciences — Paper 2. We lock down Evolution and Human Evolution, with data skills and investigation questions to boost marks 🧠🦴📈🔥 ▶️ Grade 12 Life Sciences Playlist:    • Matric Life Science - Exam Revision (Grade...   What we will cover 🌱 Natural selection: variation 🧬, selection pressure ⚖️, survival and reproduction 👶, allele frequency change 🔄; selection types — directional ➡️, stabilising 🧷, disruptive 🔀 🧬 Speciation: isolation mechanisms — geographic 🗺️, reproductive 💞, behavioural 🗣️, temporal ⏰; gradualism 🐢 vs punctuated equilibrium ⚡; African examples 🦓 🦴 Human evolution: fossils and formation 🪨, anatomical trends (bipedal adaptations 🚶, cranial capacity 🧠), culture and tools 🧰; key African sites — Taung, Sterkfontein, Swartkrans, Rising Star, Laetoli, Olduvai, Hadar 🌍 ⏱️ Dating methods: relative (stratigraphy 📚, index fossils 🐚) and absolute (Carbon-14 ⬇️ recent, Potassium-Argon or Argon-Argon ⬆️ older volcanic) 🧪 Scientific investigations & data: hypotheses ❓, variables 🔧, controls 🧪, reliability 🔁, validity ✅, graphs and tables 📊, conclusions with numbers 🔢 Weekly focus Natural Selection ✅ Notes and past questions; draw and interpret selection graphs 📈; apply to real scenarios (antibiotic resistance 🧫, camouflage 🐸). Speciation ✅ Isolation types, allopatric vs sympatric 🌄🧪; practise short explanations using memo keywords 📝; compare gradualism vs punctuated equilibrium ⚖️. Human Evolution ✅ Fossil evidence and dating ⏳; anatomical comparisons Australopithecus → Homo 🧍; site fact-cards with dates and traits 🗂️; source-based questions 🔍. Mixed Paper 2 practice ✅ Two full past papers under time ⏱️; mark with memo 🧾; error log 🧠; retest weak topics 🔁. Exam technique Describe then explain: name structure or process 🧩, give two facts ✌️, link to function or evidence 🔗. Use numbers: dates 📆, cranial capacities 🧠, percentage changes %. Graphs: title with variables 🏷️, axes and units 📐, consistent scale 📏, accurate plotting ✔️. Investigations: testable hypothesis 🧪, IV/DV/controls 🧷; reliability = repeats/sample size 🔁; validity = control variables 🎯. Avoid pitfalls: humans did not evolve from chimps 🚫🐒; C-14 not for million-year fossils ⛔; adaptation ≠ acclimatisation. How to use this program Watch the lesson ▶️, pause at each question ⏸️, answer first ✍️, then mark using our checklist ✅ to maximise your score.
