Famous quotes containing the words fossil and/or record:
“The earth is not a mere fragment of dead history, stratum upon stratum like the leaves of a book, to be studied by geologists and antiquaries chiefly, but living poetry like the leaves of a tree, which precede flowers and fruit,—not a fossil earth, but a living earth; compared with whose great central life all animal and vegetable life is merely parasitic.”
—Henry David Thoreau (1817–1862)
“We have what I would call educational genocide. I’m concerned about learning totally, but I’m immersed in the disastrous record of how many black kids are going into science. They are very few and far between. I’ve said that when I see more black students in the laboratories than I see on the football field, I’ll be happy.”
—Jewel Plummer Cobb (b. 1924)
