In 1798, a stuffed platypus specimen was delivered tothe British Museum. Reports that it laid eggs createdmuch confusion. To modern biologists, a platypus isclearly a mammal. It has fur and the females producemilk. Young animals have typical mammalian teeth thatare replaced by hardened pads of the “bill” as the animalmatures. Why do you think modern biologists can moreeasily accept that a mammal can have some reptileliketraits than scientists who were considering this animal inthe late 1700s?

Sexual reproduction enhances variability among offspring. The random alteration of DNA from parent to offspring, called mutations, also produces variable characteristics in offspring. Some mutations can be helpful, while others can be harmful and hinder survival. In this experiment, students mimicked random mutations. The mutations affected the organisms eyesight and appendages. Data was collected by the students to determine if the mutations were helpful or harmful when…
1) Of all of the robust australopithecines, I am the most primitive, dated to 2.5 mya. I have an enormous sagittal crest on the top of my head, a back of the skull that looks like A. afarensis, and am quite prognathic. My discovery seemed to justify my removal from the genus Australopithecus, and the creation of an new genus with two other species sharing similar anatomy..................... 2.
