AKIPRESS.COM - A volcanic eruption on the Galapagos Islands has raised fears the ecosystem that inspired Charles Darwin's theory of evolution may be under threat, reports BBC.

On Monday, the Wolf volcano on Isabela Island erupted for the first time in 33 years, spewing fire, smoke and lava.

Experts say the eruption poses no risk to people living on the island.

The island holds the world's only population of pink iguanas but authorities say that they are not in immediate danger.

The Galapagos National park said that the lava was flowing in a south-westerly direction.

The iguanas, "which share the habitat with yellow iguanas and giant Chelonoidis becki tortoises, are situated on the north-west flank, which raises hopes that they will not be affected," it said in a statement.

The volcano lies on the northern tip of Isabela Island, the archipelago's largest.

It is 115km (70 miles) from Puerto Villamil, the only population centre on the island.
