Redwood trees still grow tall and strong, but not all of the species is represented. Individual trees that may have possessed characteristics key to the species' survival have been cut down.
That's why researchers worked for years to sequence the genomes of the Coast Redwood and the Giant Sequoia. It's a big job... a Coast Redwood has nine times as many base pairs of DNA as a human. Emily Burns of Save the Redwoods League visits with news of the successful sequencing of the genomes. David Neale at UC-Davis also joins us, with the scientific facts and figures.
