PPT-Module 15 How Evolution Creates Biodiversity

After reading this module you should be able to Identify the processes that cause genetic diversity E xplain how evolution can occur through artificial selection E xplain how evolution can occur through natural selection. The complexity and rich diversity of life found in forests provides many vital services to human beings Nonetheless humans are destroying forest biodiversity at an alarming rate The conversion of forests to agricultural land overgrazing unsustainabl Agricultural biodiversity includes ecosystems animals plants and microorganisms related to food and agriculture Today most species of crops and domesticated livestock are the result of thousands of years of human intervention such as selective breed The Processes and. Outcomes of Evolution. What process do you think produce the biodiversity of life on Earth? . Microevolution. is evolution on a small scale, and it results in changes in the proportion of genes in a population.. Do Now. Turn in Chapter 3 Homework. Turn in Ocean Acidification Lab.

Chapter Overview Questions. How do scientists account for the development of life on earth?. What is biological evolution by natural selection, and how can it account for the current diversity of organisms on the earth?. History of Evolution. The evolution of life is linked to the physical and chemical evolution of the earth.. Life on earth evolved in two phases over the past 4.7 -4.8 billion years.
