BIOL 520 INTRODUCTION

  MICROEVOLUTION For this week’s module blog post I picked evidence of evolution as microevolution. The textbook definition of Microevolution is, “Microevolution is defined as changes in the frequency of a gene in a population. These are subtle changes that can occur in very short periods of time and may not be visible to a casual observer ” . Microevolution is the change in allele frequencies that occurs over time within a population happens due to four different processes: mutation, selection, gene flow, and genetic drift.                                                                                 http://www.mgcub.ac.in/pdf/material/20200418150944292dfa7f63.pdf Antibiotic, fungicide resistance has become a leading problem i...

             ·          In your own words, how would you explain what evolution is?      The existence of evolution is associated with all realms of our life. Human civilization has evolved from the ancient era to today’s modern world. Once human was totally dependent on nature for food for survival. For better possibilities of survival over time, humans adopted new methods of growing food. Now humans do not rely only on nature for food rather through technology it is possible to produce meat in the lab today. I found an article A team led by Shoji Takeuchi at the University of Tokyo in Japan has found a new way to grow cow muscle cells in culture . To me, the biological definition of evolution is a noticeable alteration of characteristics over time due to the mutation of genes through the environment for the survival of a population. The alteration of the gene is inheritable to the ...
