Sign In 1. Credit for the concept of epigenesis goes to which of the following ?
Answer Explanation
The concept of epigenesis is often attributed to Aristotle, an ancient Greek philosopher and scientist. Aristotle proposed the idea of epigenesis in contrast to the theory of preformation, which was prevalent at the time. Epigenesis suggests that the development of an organism is a gradual process involving the progressive formation of new structures, while preformation proposed that all the necessary parts of an organism were preexisting in miniature form. Aristotle’s ideas on epigenesis laid the groundwork for our modern understanding of embryology and development. Image Source After Lysippos, Public domain, via Wikimedia Commons
2. Our genome sequence is more than 98% similar to that of which of the following ?
Answer Explanation
Our genome sequence is more than 98% similar to that of chimpanzees (Pan troglodytes). This high degree of genetic similarity between humans and chimpanzees is often cited as evidence for our shared evolutionary history. It highlights the fact that humans and chimpanzees share a common ancestor and have diverged relatively recently in evolutionary terms. Despite this genetic similarity, the remaining differences in our genomes have led to the distinct physical and behavioral characteristics that separate us from chimpanzees.
