  1. Bringing back the dinosaurs By David Wong

  2. Jurassic Park • Michael Crichton imagined finding a prehistoric blood sucking insect preserved in amber. • By drilling into the insect and removing genetic material and cloning it they produced dinosaurs.

  3. Famous paleontologist Jack Horner said “if you got something out of that insect and cloned it you would have a roomful of mosquitoes”.

  4. Go to the Dinosaur • The only way to obtain dinosaur DNA is to find it in a dinosaur and extract it from the soft tissue. • Mary Schweitzer found interesting structures in T-rex bones that resembled red blood cells.

  5. They turned out to be heme which is what hemoglobin is made of. • But by studying the soft tissue they learned a lot about dinosaurs

  6. The main thing they learned was that dinosaur DNA decayed either long ago or almost immediately after the bone was opened up. • So cloning a dinosaur is not yet possible and probably never will be

  7. Jack Horner said that if you can’t clone a dinosaur build a dinosaur. • Birds are technically living dinosaurs and are classified as avian dinosaurs (witch are modern birds) • Since the chicken is a dinosaur we can fix the chicken to make it more like a non-avian dinosaur (witch are all the extinct dinosaurs)

  8. Biological modification tools • Selection: through selective breeding you can alter a species appearance over the course of several generations. • Selection accounts for the many breeds of dogs

  9. Transgenesis • The process of transplanting genes from one organism to another • Like these glowing rats have a jellyfish gene that allows a chemical reaction that causes them to glow

  10. Atavism Activation • The modification of an organism by bringing out existing ancestral genes that are no longer expressed and suppressing modern genes that are expressed. • Dr Hans Larsson (McGill university) is looking for a way to turn off the gene that causes the embryonic chickens fingers to fuse in to wings.

  11. As well as the wing, the teeth, and the tail of the chicken can also be recovered • By turning off the gene that suppresses the tail growth and stimulating the gene that forms teeth

  12. In conclusion • It is unlikely that we could clone a dinosaur from a mosquito or even from a dinosaurs tissues • Genetically modifying a chicken is probably the only way we could make a dinosaur • Atavism activation is the most efficient way to make a dinosaur-like creature
