Mammoths pictured here are an extinct relative of the current elephants that are known today. Mammoth DNA has been discovered frozen in time with little breakdown of the DNA sequence. Recently scientists have been able to use gene sequencing to piece together fragments of extinct mammoth DNA and elephant DNA. Their work will be used to create a complete sequence of DNA that could be used in the cloning of a mammoth. In order to complete this task, researchers would need to insert the DNA into an embryo and place that embryo inside an Asian elephant in order to grow and develop. What would be an ethical concern associated with using an endangered Asian elephant to grow the embryo containing the cloned mammoth DNA?

a)

Cloning is a technology that is too new to be used in action without further research on the topic.

b)

The introduction of a new mammoth species would increase biodiversity for the already declining elephant population.

c)

Using gene sequencing to alter the DNA of an extinct organism could produce a new species of elephant completely different from the mammoth.

d)

Since the Asian elephant is already at risk for extinction, using this elephant to grow a mammoth instead of its own species could further lead to the decrease in the Asian elephant population.
