9. Common thread?
Humans FORCED them
to EXTINCTION
WWF global ESTIMATES that at
LEAST 10,000 species go
EXTINCT every year
10. Probable Reason for
Extinction
• Paul Martin, an
American
anthropologist, pointed
out that MEGAFAUNAL
EXTINCTIONS were due
to the introduction of
HUNTING and
DOMESTICATION
TECHNIQUES by our
early ancestors
• OVERKILL Hypothesis
11. De-extinction
process by which humans
GENETICALLY ENGINEER
embryos of extant species to
hopefully bring back extinct
relatives
18. Results
Bucardo Gastric-Brooding Frog
Only one female Spanish
Ibex got pregnant
Life span of revived
bucardo was 7 minutes;
Died because of lung
defects
Embryo’s average life span
is 10 days
Genetically IDENTICAL to the extinct species
26. Are we playing God?
“Did we play God when we
drove these species to
extinction?”
“It was ENTIRELY human
efforts that made them
extinct.”
27. Are we playing God?
“Humans have made a HUGE
hole in nature…We could
consider bringing them back
to a world that MISSES them.”
“What I think is important is that, if it's
clear that we exterminated these
species, then I think we not only have a
MORAL OBLIGATION to see what we
can do about it, but I think we've got a
MORAL IMPERATIVE to try to do
something, if we can.”
28. What are we going to do with the
revived species?
