And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Swallows learn to open an automatic door to get access to their preferred nesting site.
"When the University of Victoria in Canada opened a new campus bike centre in the parkade located under the University Centre last November, motion-activated doors were installed to discourage swallows from nesting in the new facility. But when the swallows returned to their familiar nest sites a few weeks ago, they were undeterred by this peculiar impediment: they quickly learned how to open the doors by flying in front of the infrared motion detector, as you see in this video."

Well, technically they ARE evolved dinosaurs.
ReplyDeleteThis is evidence of advanced development. Next the swallows will master the internet and start blogging.
