In the first part of your essay provide a brief account of the major findings outlined in the article and its potential broader impact. This must not be a simple restatement of the abstract of the paper. Instead, you should present key points from the paper in your own words for a wider and non-specialist but scientifically literate audience and then set it in the broader context of its potential impact. Use a writing style that engages the reader and dont assume background knowledge greater than that of a second-year undergraduate in psychology or biology. Do not copy or paraphrase from the paper.

In the second part of your essay you should analyze the ethical issues raised by the use of animal subjects in this paper from at least two contrasting philosophical perspectives on ethics. You should reference relevant sources and consider how public attitudes to this type of research might change over the next decade.
