Darwin’s Theory of Evolution
- There is variation in every population
- Organism compete for limited resoureces
- Organisms produce more offsprings than can survive
- Organisms pass genetic traits on to their offsprings
- Those organisms with the most beneficial traits are more likely to survive and reproduce (Natural Selection)
Darwin imagined it might be possible that all life is descended from an original species from ancient times. Probably all organic beings which have ever lived on this earth have descended from some one primordial life form. From so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved. (The Origin of Species)

A Dream (William Blake)
Once a dream did weave a shade
O'er my Angel-guarded bed,
That an Emmet lost its way
Where on grass methought I lay.
Troubled, 'wilder'd, and forlorn,
Dark, benighted, travel-worn,
Over many a tangled spray,
All heart-broken I heard her say:
``O, my children! do they cry?
Do they hear their father sigh?
Now they look abroad to see:
Now return and weep for me.''
Pitying, I drop'd a tear;
But I saw a glow-worm near,
Who replied: ``What wailing wight
Calls the watchman of the night?
``I am set to light the ground,
While the beetle goes his round:
Follow now the beetle's hum;
Little wanderer, hie thee home.''
