Item description

If you’re looking for good quality worksheets on Natural Selection and Evolution that will save you heaps of time AND provide excellent practice/revision for your students, this resource is just what you need. Suitable for years 10 – 12, Natural Selection and Evolution can be used for classwork, homework, revision and even tests.

Natural Selection and Evolution consists of ten handy printable black-and-white Student Worksheets (PLUS Answer Sheets) that will enhance your students’ understanding of this fundamental topic in biology.

Natural Selection and Evolution covers the following:

  • natural and artificial selection

  • importance of variation in a population

  • speciation

  • evidence for evolution: fossil record, DNA-DNA hybridisation, comparing DNA/amino acid sequences, transitional fossils, comparing embryos, homologous structures, vestigial structures, biogeographic distributions

  • determining relatedness between species

  • changes in populations: gene flow, genetic drift and the bottleneck effect

  • phylogenetic trees

  • the molecular clock concept

Along with printable worksheets, a digital (PowerPoint) version of this resource is included here at no extra cost, giving teachers a choice as to which they prefer to use – taking into account the different learning styles of their students.

Natural Selection and Evolution is not just about answering questions. Your students will enjoy the ‘active’ nature of the tasks here, including:

  • analysing diagrams

  • completing ‘fill-in-the-gaps’ passages

  • analysing and recording secondary data

  • drawing phylogenetic trees

  • completing a fun word find

  • using simple PowerPoint tools to add text, insert and format shapes and ‘drag and drop’ moveable objects (digital version)

Natural Selection and Evolution includes an Answer Key (PDF) with images in full colour that look great on the big screen and can be used to facilitate good class discussion. Answers provided are also highly detailed, so there is no need to research or fact-check here; it’s all been done for you!

I hope you and your students find this product useful and that you enjoy using it as much as I enjoyed creating it!
