91605 Processes of Evolution - Home Use

This Digital Resource has less sophisticated functionality as it was one of the first we developed and is priced to reflect this.

This resource covers the things you need to know and be able to do for the NCEA Level 3 Achievement Standard 91605 (Biology 3.5) Demonstrate understanding of evolutionary processes leading to speciation.

What you'll learn

In this resource you'll find answers to questions like:

• What is a gene pool and what is allele frequency?
• What is gene flow?
• What is genetic drift, founder effect and bottleneck effect?
• What is inbreeding and what is‚ outbreeding?
• What is natural selection, including disruptive selection, stabilising selection, directional selection and sexual selection?
• What is a phylogenetic tree and what is the role of molecular biology?
• What are genetic mutations, including gene mutations, chromosomal mutations and ploidy - and what are their roles in evolution?
• What is speciation and how do reproductive isolating mechanisms function?
• What is allopatric speciation and what is sympatric speciation?
• What is instant speciation/polyploidy?
• What can we determine from fossil evidence?
• What evidence of evolution‚ can we attain from genetic analysis?
• What evidence of evolution can we attain from biogeographical factors?
• What is gradualism and punctuated equilibrium; how do these rates of evolution differ?
• What is divergent evolution and adaptive radiation?
• What is convergent evolution?
• What are the differences in comparative anatomy between homologous and analogous structures?
• What is co-evolution and what species can we observe to have co-evolved?
