 .p021 [ [https://en.wikipedia.org/wiki/J._B._S._Haldane | J.B.S. Haldane ]] You can drop a mouse down a thousand-yard mine shaft and, on arriving at the bottom, it gets a slight shock and walks away. A rat would probably be killed, though it can fall safely from the eleventh story of a building, a man is broken, a horse splashes.
 .p023 sprinting up stairs 7x to 14x more energy expensive than sitting reading
 .p023 insect flight 100 beats per second, 50 to 150x more energy expensive than rest
 .p024 oxygen radicals accompany energy delivery
 .p025 juvenile [[https://en.wikipedia.org/wiki/Mayfly | mayfly ]] nymphs molt in streams for years, minutes to days as a reproductive adult
 .p026 [[ https://en.wikipedia.org/wiki/Cicada | Cicada ]] nymphs as much as 17 years feeding on root sap underground, synchronized mass emergence for weeks
 .p027 no insect species with documented adults living longer than 1 year in the wild
 .p028 [[ https://en.wikipedia.org/wiki/Monarch_butterfly | Monarch Butterfly ]] many generations per year, flying to southern Mexico in autumn, north in spring. The southern phase lasts as long as 8 months, migration and summer phases weeks
 .p029 insect flight wings fragile, covered by hard [[ https://en.wikipedia.org/wiki/Elytron | elytron/elytra ]] when not flying

 .'''p031 ch03 Pterosaurs: The First Flying Vertebrates'''

 .p042 ''wild'' [[ https://en.wikipedia.org/wiki/House_sparrow | house sparrows ]] live at least 19 years, 3 years in captivity
 .p043 [[ https://en.wikipedia.org/wiki/Archaeopteryx | Archaeopteryx ]] not a bird, no keeled breastbone. Probably extra boost for hops, like "flying" squirell
 .p044 true bird evolved before 66 mya, a few survived Chicxulub impact
 .p045 Fig 4.1 an 81yo [[ https://en.wikipedia.org/wiki/Pink_cockatoo | Major Mitchell's cockatoo ]], the world's longest lived bird at Chicago's Brookfield zoo
 .p049 [[ https://en.wikipedia.org/wiki/Albatross | Albatrosses ]] mate for life, 1 egg most years
 .p050 Albatross named "Wisdom" more than 70 years old
 .p051 current mate "Akeakamai", Hawaiian for "lover of wisdom"
 .p051 LQ (life quotient) of 5.2, 5.2 times longer than average same-size zoo mammal
 .p052 [[ https://en.wikipedia.org/wiki/Manx_shearwater | Manx Shearwater ]] at least 55 years, LQ of 6, migrates annually from North Atlantic to Brazil or Argentina
 .p053 Turkey breast meat (flight muscle) adapted for energy bursts, "drumsticks" dark with myoglobin for running endurance

 .p055 twice fly 600 miles nonstop migrating across Caribbean, live more than 9 years
 .p055 [[ https://en.wikipedia.org/wiki/Broad-tailed_hummingbird | broad-tailed hummingbird ]] at least 12 years
 .p056 birds make fewer free radicals than mammals, can withstand more free radical damage
 .p057 Medical researchers study short-lived animals, author desires much longer studies
  . so we can live longer, so researchers have time for longer studies :-)

 . '''How many atoms in human body?'''
  . Total Earth biomass 550 GT carbon 5.5 x 1e2 x 1e9 x 1e6 (tonnes per gram) = 5.5e17 grams
  . carbon is 12 amu and 12% of the atoms in human body
  . Avogadro's number 6e23, hence one gram of human carbon is 5e22 atoms
  . Associated with (100/12)*5e22 ≈ 4e21 total atoms per gram of human carbon
  . Fermi estimate: Total Earth biomass 5.5e17 * 4e21 atoms = 2e39 biomass atoms ''if humans representative''
  . There are 1e22 to 1e24 stars in the universe
  . Thousands of asteroids and trillions of comets and icy bodies orbit the Sun
  . Perhaps 3e12 comets per star times 1e24 stars is 6e36 icy bodies in the universe, not counting unbound bodies
  . that's a LOT of physics
  . Both biology and physics are complicated ... or simple, if one is a simpleton

I. LONGEVITY IN THE AIR

  • p019 ch02 The Origin of Flight

  • p020 2.5 meter Arthropleura millipede 300 mya

  • p021 [ [https://en.wikipedia.org/wiki/J._B._S._Haldane | J.B.S. Haldane ]] You can drop a mouse down a thousand-yard mine shaft and, on arriving at the bottom, it gets a slight shock and walks away. A rat would probably be killed, though it can fall safely from the eleventh story of a building, a man is broken, a horse splashes.

  • p023 sprinting up stairs 7x to 14x more energy expensive than sitting reading
  • p023 insect flight 100 beats per second, 50 to 150x more energy expensive than rest
  • p024 oxygen radicals accompany energy delivery
  • p025 juvenile mayfly nymphs molt in streams for years, minutes to days as a reproductive adult

  • p026 Cicada nymphs as much as 17 years feeding on root sap underground, synchronized mass emergence for weeks

  • p027 no insect species with documented adults living longer than 1 year in the wild
  • p028 Monarch Butterfly many generations per year, flying to southern Mexico in autumn, north in spring. The southern phase lasts as long as 8 months, migration and summer phases weeks

  • p029 insect flight wings fragile, covered by hard elytron/elytra when not flying

  • p031 ch03 Pterosaurs: The First Flying Vertebrates

  • p039 Pterodaustro Guinazui pterodactyl hundreds of fine teeth, probably filter-fed like a baleen whale

  • p041 ch04 Birds: The Longest-Lived Dinosaurs

  • p041 bar-tailed godwit flies nonstop from Alaska to New Zealand in nine days and nights

  • p042 wild house sparrows live at least 19 years, 3 years in captivity

  • p043 Archaeopteryx not a bird, no keeled breastbone. Probably extra boost for hops, like "flying" squirell

  • p044 true bird evolved before 66 mya, a few survived Chicxulub impact
  • p045 Fig 4.1 an 81yo Major Mitchell's cockatoo, the world's longest lived bird at Chicago's Brookfield zoo

  • p049 Albatrosses mate for life, 1 egg most years

  • p050 Albatross named "Wisdom" more than 70 years old
  • p051 current mate "Akeakamai", Hawaiian for "lover of wisdom"
  • p051 LQ (life quotient) of 5.2, 5.2 times longer than average same-size zoo mammal
  • p052 Manx Shearwater at least 55 years, LQ of 6, migrates annually from North Atlantic to Brazil or Argentina

  • p053 Turkey breast meat (flight muscle) adapted for energy bursts, "drumsticks" dark with myoglobin for running endurance
  • p054 ruby-throated hummingbird 40℃ 104℉ endothermic, 80 wingbeats per second

  • p055 twice fly 600 miles nonstop migrating across Caribbean, live more than 9 years
  • p055 broad-tailed hummingbird at least 12 years

  • p056 birds make fewer free radicals than mammals, can withstand more free radical damage
  • p057 Medical researchers study short-lived animals, author desires much longer studies
    • so we can live longer, so researchers have time for longer studies :-)

II. LONGEVITY ON THE EARTH


  • How many atoms in human body?

    • Total Earth biomass 550 GT carbon 5.5 x 1e2 x 1e9 x 1e6 (tonnes per gram) = 5.5e17 grams
    • carbon is 12 amu and 12% of the atoms in human body
    • Avogadro's number 6e23, hence one gram of human carbon is 5e22 atoms
    • Associated with (100/12)*5e22 ≈ 4e21 total atoms per gram of human carbon
    • Fermi estimate: Total Earth biomass 5.5e17 * 4e21 atoms = 2e39 biomass atoms if humans representative

    • There are 1e22 to 1e24 stars in the universe
    • Thousands of asteroids and trillions of comets and icy bodies orbit the Sun
    • Perhaps 3e12 comets per star times 1e24 stars is 6e36 icy bodies in the universe, not counting unbound bodies
    • that's a LOT of physics
    • Both biology and physics are complicated ... or simple, if one is a simpleton
