Darwin's Grandpa

so I started to write my paper about the history of evolutionary theory, but then i got distracted...anyway while researching i came across this poem that i wanted to share with the class. it's by Darwin's grandfather:

Organic life beneath the shoreless waves
Was born and nurs'd in ocean's pearly caves;
First forms minute, unseen by spheric glass,
Move on the mud, or pierce the watery mass;
These, as successive generations bloom,
New powers acquire and larger limbs assume;
Whence countless groups of vegetation spring,
And breathing realms of fin and feet and wing.

Erasmus Darwin. The Temple of Nature. 1802.
