Origin Of Species - Chapter 5 : Laws Of Variation

If you’ve never read “On the Origin of Species,” you should at least listen to this video series whilst going about your other activities! It gives a very solid and interesting foundation to evolution, and even if you understand the basic tenets of the theory, hearing the words of the most important progenitor of the field gives so much insight!

Infinite Cave in Vietnam

The amazing photo featured above was taken in a huge cavern complex within the bowels of central Vietnam – in Phong Nha-Ke Bang National Park. During the spring of 2009, a team of spelunkers began exploring a mountain river cave in Vietnam and discovered a passage carved by a subterranean river millions of years ago.

Like a castle on a knoll, a limestone formation shines beneath a skylight in Hang Son Doong Cave. A monsoon storm had just filled the pool in the foreground, signaling that exploring season was ending. Referred to as the “infinite cave” this underground labyrinth is more than 2.5 mi long (4.0 km).
