A Theory that Explains Everything

The Urge to Speciate

 

Why is there…?

•      War

•      Terrorism

•      Crime

•      Dictatorships

•      Poverty

•      Racism

•      Sexism

•      Ethnic Discrimination

Urge to Speciate

•      We’ve been one species for too long.

•      A new species will allow our offspring to survive in the environments of the future.

•      Evidence for the trend to speciate is obvious!

We speak different languages

We speak the same language differently

•     “A lorry of nappies overtook your saloon.”

•      petit-dιjeuner vs. dιjeuner;

•      dιjeuner vs. dξner;

•      dξner vs. souper; souper.

•     Ice cream bar = ice cream pop = iced lolly

We speak different languages in the same country

•      Canada: English, French

•      Belgium: French, Dutch, German

•      Switzerland: German, French, Italian, Romanche (and Yodel?)

•      Pakistan: Urdu, Punjabi, Pashto, others.

•      China: Mandarin, Cantonese

•      Spain: Castilian, Catalan, Galician, Euskera (Basque), and others.

We label bodies of water differently

•     Sea of Japan – East Sea

•     English Channel – La Manche

•     Persian Gulf – Arabian Gulf

•     Gulf of Mexico – Gulf of Texas (proposed by red states?)

We have different religions

Different nations

We eat differently

We are different races

We have different “isms?”

Would you change?

Would a UU likely consider marriage with:

•          A member of the Christian right?

•          A conservative Republican?

•          An Islamic fundamentalist?

•          A male/female chauvinist?

•          A person who would not learn English?

•          A homeless or poverty stricken person?

•          An uneducated person or a “redneck”?

•          A person who will always wear non-western native clothing?

•          A person who prefers: (% of world population)

–        Sleeping on mats (50+)

–        Using a squat toilet (90)

•          And live in a dictatorship, theocracy, nudist colony, or Texas

We’re different!  Why?

Definitions & Basic Concepts

•      Species

•      Population

•      Evolution

•      Role of Competition

•      Changing Environments

•      Isolation

Species is the Basic Unit

Similar and able to reproduce fertile offspring.

Population

A group of the same species living in the same area.

Evolution operates at the population level.

Evolution

•      Controversy results from a gross misunderstanding of the theory

 

 

 

•      One species does not morph into another

•      Natural Selection (Charles Darwin,1859)

                                Young of any species must survive long enough to produce     young of their own and pass on the good-survival genes to subsequent generations.

Competition

•      Urge to compete for available resources

•      Sometimes intense and even violent

•      Urge is inherited– gene driven

Responsive Reading

•   Please read the italics in yellow and alternate with my reading of the non-italics in white.

Humans Are Animals

•      Humans are animals, not plants. 

–  Plants can create food from water, carbon dioxide, and sunlight.  Animals must consume other plants and animals. 

•      We are not plants (e.g., trees, algae, or ferns).

–  Although we are animals (as are elephants, shrimp, and monkeys), we cannot interbreed with other non-human animal species. 

•      We are a separate species.

Humans are Mammals

•      Humans are mammals, not reptiles. 

–   Reptiles hatch from external eggs and must immediately search for food after emerging from the eggshell.  Instead, mammals produce live young and suckle their young. 

•      We are not reptiles, as are alligators, lizards, and snakes. 

–   Although we share similar characteristics with other mammals like dogs, skunks, and baboons, we are not any of these either. 

–   Although we are mammals, we cannot interbreed and produce fertile offspring with other non-human mammals. 

•      We are a separate species.

Humans Are Primates

•      Humans are primates, not ungulates (hoofs). 

–   Ungulates have hoofs and are mostly plant eaters. Primates have grasping hands and feet and eat both plants and animals. 

•      We are not ungulates, as are pigs, cows, and sheep. 

–   Although we share similar characteristics with other primates like lemurs, monkeys, and apes, we are not any of these either. 

–   Although we are primates, we cannot interbreed and produce fertile offspring with other non-human primates. 

•      We are a separate species.

 

In summary, our species consists of humanoid, primate mammalian animals

Environments Vary and Shift

•      Borders change 

•      The Earth is dynamic.

Environmental Changes

•      Bad

–  Habitats destroyed. 

–  Species become extinct.

•      Good 

–  New species survive and flourish. 

–  Change can bring needed water, mineral-rich soils, milder climates

Human Isolation

•      Most humans tend to live in or return to the area of their families.

–   Race, ethnicity, language, national identity, and religion help to maintain this isolation. 

•      Development of races may have been a precursor to early attempts at speciation.

•      But working against isolation is…

Globalization

•      Migrate to distant lands:

–   Job, overseas assignments

–   Retirement, better climate

–   better standard of living

–   more freedom

–   lower taxes.

•      Globalization, diversity, and tolerance have increased worldwide

•      If there were….

Complete Isolation

•      E.g., emigration to distant planets or moons on distant solar systems

•      Gene pool not shared with others on Earth

•      Nearest stars (may have habitable planets). 

–    Proxima Centauri (V645 Cen) 4.2 l.y. (100,000,000,000,000 miles)

–    Rigal Kentaurus (Alpha Cen A and B) 4.3 l.y.

–    Barnard’s Star Wolf 356 (CN Leo) 7.7 l.y.

–    Barnard’s Staff Wolf (BD+36 2147) 8.2 l.y.

•      Isolated enough that evolution can proceed without influences from other human populations on Earth.

Getting there?

•      At 35,000 mph (~ Voyager 1 and 2 space probes)

–  Minimum travel time Proxima Centauri is 350,000 years (~10,000 generations)

–  If the nearest is not habitable, go 300,000 years longer to the next system.

–  May travel in cryogenic hibernation, or

•      Time-warp (approaching the speed of light)—cutting travel time to 10 years.

Speciation

•             Evolution +

•             Changing environments +

•             Isolation =

 

1. Evolution

•      At first, species is well adapted and multiplies

•      Diversity produces some offspring that would do better in different environments

–  They are less abundant or become extinct.

2. Environmental Change

•      The Earth is dynamic- changes occur in:

–  Solar radiation, ocean currents, climate, soil, food and water sources, predator/prey relationships.

•      Change may give diverse individuals a better chance for survival, others become extinct.

3. Isolation

•      Diverse parts of populations are divided from mainstream parts by:

–  Geographic barriers: valleys, sea rise, ice and ice free areas, loss of land bridges, mountains

–  Environmental deterrents: restriction of habitat, introduction of predators along migration routes, sparse populations

–  Cultural differences: finding and attracting mates; nations, languages, religions, isms.

Speciation

•      New species is produced

•      Cannot interbreed and produce fertile offspring with original species

•      Intra-species competition abates

Speciation Aborted

•      No new species is produced

•      Continuous interbreeding

•      Intra-species competition intensifies- war, crime, terrorism, etc.

So…

•      We can’t speciate

 

•      But…we can tame the competitive gene.

 

 

 

•      How?

 

Taming

•     (Evolution + Diversity) + Isolation

Taming (evolution + diversity)

•      = genetic engineering

 

•      Find gene and fix (too far?).

•      Who make the decisions?

Taming (Isolation)

•             Fighting isolation

–           Communication.

–           International TV

–           Overseas vacations.

–           Student exchanges.

–           Language education.

–           Exotic foods

–           Intermarriage

–           International agreements/free trade based on social democracy.

–           World health and family planning.

–           Objectivity in politics

–           Civic pride, vote, write to elected officials.

–           Join open clubs, be friendly, and smile.
