We Are Vulnerable to Extinction

  1. 1. Prelude – “Das Rad”A chat amongst stones can take a while...
  2. 2. We are vulnerable to extinction Think Critically Discover Discuss ctgarry
  3. 3. Scope Check
  4. 4. Scope Irrelevant • When was the earth hatched? “a long time ago”
  5. 5. Scope Not Interested • When will it all go poof? “not for a while”
  6. 6. Scope Yawn • Evolution “That which adapts survives”
  7. 7. Scope Things to make you go “Brrrr” • Divine punishment “dinosaurs weren’t allowed on the ark”
  8. 8. Scope Providence • The favored species “He made the Earth for us”
  9. 9. Scope Which Earth?
  10. 10. Toolsto use in discussion of extinction
  11. 11. Tools Scientific Method • Disposing Pre-conceived notions and filters in favor of… “facts?”
  12. 12. Tools Terms and Analysis • Describing Time Spans – Human History versus Facebook History • Making Inferences – Things at the bottom are older • Classifications – Things that are similar can be grouped together
  13. 13. It’s hard out here for a chimp
  14. 14. Tools: Inferences Sparkly Words Geologic Features • Layering • Group layers into 11 “periods” – No dinosaurs in last 2 periods • Chemical Decay Rates
  15. 15. Tools: Time spans Sparkly Words Describing Geologic Time spans• Looking at early “records” of Earth, we label increasingly refined segments• SuperEon > Eon (4) > Era (10) > Period (22) – Epoch (7 in the last two periods)
  16. 16. Tools: Classifications Sparkly Words Taxonomic Classifications • Species – All humans alive today are one species because they constitute a group of individuals that could breed with themselves but not with any other group.
  17. 17. Tools: Classifications Sparkly Words Taxonomic Classifications PRIMATE Old World Monkey Hominid Hab • It can go like this then: Sapi ilis ens Au Homo • Species • Groups of Similar Species = GENUS • Groups of Groups of Similar Species = FAMILY • Groups of Groups of Groups of Similar Species = ORDER • etc
  18. 18. Tools: Classifications Sparkly Words Taxonomic Classifications • One sign of life versus another – How does it relate? What’s similar? – What’s different? Phylum Spinal cords Chordate Class Live birth; nurse Mammal Order Looks “monkey-like” Primate Family Looks “great ape” Hominid Genus Looks “human” Homo Species Humans Sapiens
  19. 19. Tools Sparkly Words Fossils • No bones…only stones • Locations – Siberia – BC – Australia – Texas – Utah – Scotland – Etc What do they have in common?
  20. 20. Tools Sparkly Words Extinction Level Event (ELE) “major mass extinctions far exceeding background extinction rate”
  21. 21. Terminology, Classification, Inferences are tools used in discussion of extinction andcan be reused to think critically, discover and discuss our vulnerability to it
  22. 22. Tools Which is it? • WE are vulnerable to extinction – NO! • We are vulnerable to extinction – NO! • We are vulnerable to extinction – YES!
  23. 23. Frame it up
  24. 24. Frame Earth as a Project First 88 % of earth’s history • Requirements Hell – molten requirements swirled • Alpha – continental mockups formed • Dogfood – the earliest friendly users were introduced – atmosphere provided, etc Ends: microscopic hard-shelled users arrive
  25. 25. Frame Earth as a Project • Requirements • Alpha • Dogfood • Early Adopters • Power Users RC1: Early Adopters Fish, • Noobs Arthropods Amphibians Reptiles
  26. 26. Frame Earth as a Project • Requirements RC1: Early Adopters crashed a lot • O-S extinction event: • Alpha • • 27% of all families 57% of all genera • Dogfood • D-C extinction event: • Top spots were all traded throughout the • Early Adopters last half: Fish, arthropods (things with shells), amphibians and reptiles • Power Users • 19% of all families • 50% of all genera • Noobs • 70% of all species
  27. 27. Frame Earth as a Project • Requirements • Alpha • Dogfood • Early adopters • Power Users • Noobs RC2: Power Users archosaurs dominate RC3: Power Users Redux dinosaurs rule
  28. 28. Frame Earth as a Project • Requirements • RC 2 “Great Dying” • Alpha • Out: Mammal-like reptiles • 57% of all families; 83% of all genera • Dogfood • In: Archosaurs, Therapsids Large Amphibians • Early adopters • Power Users • RC 3 “Dawn of Jurassic” • Out: Archosaurs; Therapsids; Amphibians • Noobs • 23% of all families; 48% of all genera • In: Dinosaurs
  29. 29. Frame Earth as a Project Most recent 1.5 % of earth’s history: • Requirements RC4 becomes v1.0 • Alpha Tropical period heading for cooling • Dogfood Small users prosper, fauna diversify • Early adopters v1.1: Mammals and birds revised • Power Users Introduction of “Hominids” • Noobs v1.2: Introduction of “Homo” (Humans)
  30. 30. Frame Earth as a Project • Requirements • RC4 Mass Extinctions • Alpha – Dinosaurs out – Mammals in • Dogfood • 17% of all families • Early adopters • 50% of all genera • 75% of species • Power Users • Noobs

  36. 36. The Story So Far
  37. 37. ELE The Story So Far • Species go extinct …which is advantageous for other species
  38. 38. ELE The Story So Far • Extinction takes a while …or does it?
  39. 39. ELE The Story So Far • Mass Extinctions are not 100% across species • Mark the transitions from span to span • Data incomplete …is that supposed to make me feel better? if “me” = “humans” maybe not….
  40. 40. ELE The Story So Far • We care about extinctions because we are only one species …We may just go in a background extinction
  41. 41. ELE The Story So Far • Extinctions don’t destroy the environment …the Earth persisted through all ELE we can detect
  42. 42. Let’s Get Down to It
  43. 43. ELE Questions • Do you personally know how much and in what way we depend on other species? …direct use of a dozen varieties of plants and one or two meats …but what does it take to support those?
  44. 44. ELE Questions • How many species here? …Human Biome Project shows 10,000 +
  45. 45. ELE
  46. 46. ELE Questions • How much control do you think we (as a species) have over: • favored terrain • atmosphere • food supply • our own bodies? …40% of humans poop outside not even a bucket…
  47. 47. ELE Questions • Will we adapt fast enough to react to a sudden event? • What does “sudden” even mean? 0.00000004 % …will it matter?
  48. 48. ELE Adaptation The Ron White Factor • “There was a guy down in Florida who said that, at the age of 53 years old, he was in good enough physical condition to withstand the wind, rain and hail of a force-3 hurricane. • “Now, let me explain somethin’ to ya: it isnt that the wind is blowin’, its what the wind is blowin’. • “If you get hit by a Volvo, it doesnt matter how many sit-ups you did that morning.”

What then must we do? Tolstoy asked the same question. He wrote a book with that title. He got so upset about the poverty in Moscow that he went one night into the poorest section and just gave away all his money. You could do that now. Five American dollars would be a fortune to one of these people.GUY: Wouldnt do any good, just be a drop in the ocean.BILLY: Ahh, thats the same conclusion Tolstoy came to. I disagree.GUY: Oh, whats your solution?BILLY: Well, I support the view that you just dont think about the major issues. You do whatever you can about the misery thats in front of you. Add your light to the sum of light. You think thats naive, dont you?GUY: Yep.BILLY: Its alright, most journalists do.GUY: We cant afford to get involved.
