Before accepting his present position at Utah State University, Randy Lewis had started his research in synthetic biology in Wyoming, where he was once interviewed on the nature and purpose of his activities in the domain of spider goats:
I'm convinced that spider goats might be considered as a spectacular symbol of the vast array of developments that await us in the domain of genetic engineering. An observer might ask: What is the supposed right of scientists such as Randy Lewis to fiddle with the archaic natural biology of an innocent animal such as a goat, and transform its offspring into monsters whose milk is full of spider webs? That kind of question, to my mind, is misguided, if not stupid. There are many excellent reasons behind the goal of learning how to manufacture artificial spider webs. Spider goats would appear to be a plausible approach to meeting this challenge. These weird creatures of modern science, capable of producing in their milk the substance of spider webs, do not appear to suffer in any way whatsoever as a consequence of this research. So, why might we imagine any kind of evil in this domain?
