Concept explainers
To explain: The results of the experiment that was conducted by Bartel and Szostak.
Introduction: Most of the scientists favor RNA to be the very first macromolecule to be found in the protobionts. Comparative studies have shown DNA and proteins to be less versatile in comparison to RNA. During the origin of life on Earth, it is believed to be RNA dominant world. RNA world is believed to exist during the beginning of life on the earth. It is a hypothetical period where both, the information required for maintaining life and the catalytic activities inside a cell were present on RNA itself.
To explain: The influence of the study conducted by Bartel and Szostak on understanding of the evolution of life on Earth.

- Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding? Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly.
