Do you think it is important that all species be prevented from going extinct? Explain your reasoning. Also, there is a process called “de extinction” where scientist use DNA from an extinct species and genetically “recreate” that species. Do you think this is a good idea? Explain you reasoning.
Scientists are studying two populations of the same species of sea turtle. One population is quite small, with only 18 individuals, and the other is much larger, with 147 individuals. If a genetic factor such as a mutation were introduced to both populations at the same time, what could scientists predict about the impact?
What is Speciation?
A) Movement of a population from one area to another
B) Becoming part of an adopted species
C) Creation of a new species
