"Shell middens" accumulation
"Shell middens" accumulation on the connection between the Encajonado River and the Beagle Channel. -
Biston Betularia
The butterfly Biston Betularia has provided a real example of evolution over 200 years. This specie presents a clear form and a dark form. British Naturalists have been able to prove how natural selection favoured those different forms depending on the increase or the decrease of pollution. -
Native from the Tierra del Fuego
A watercolor of a native from the Tierra del Fuego, from around the time that Charles Darwin was on his Voyage of the Beagle (1830s). Scanned from Richard Darwin Keynes, The Beagle record: selections from the original pictorial records and written accounts of the voyage of H.M.S. Beagle (Cambridge ; New York: Cambridge University Press, 1979). -

Archaeological artifact made on bird bone
Archaeological artifact made with bird bone. According to ethnographical sources, it would have been used for the manufacturing of basketry. (Lanashuaia I site). -

Typical postcard from early XXth century
Typical postcard from early XXth century showing indigenous people, in this case with a Yamana woman doing a basket. -
Iguana
Marine iguana from Bahía Tortuga (Galapagos Islands). Marine iguanas expel the accumulated salt in their organism through a sort of sneezing, followed by a saline spray that, depending on the direction in which the wind blows, may accumulate on their heads, forming a spectacular salt crust. -
"San Cristobal" Island (Galápagos)
The arrival of Darwin at the Galápagos Islands was not very glamorous. Far from the exuberance of tropical forests, Darwin came upon a group of islands hit by strong solar radiation and populated by seemingly dead vegetation, as he for example described in his depiction of leafless trees and shrubs. -
Darwin disembarks in the Galápagos
Darwin reached the Galapagos Islands on September 17th 1835, specifically the island of San Cristobal, aboard the HMS Beagle. Scientists today travel by air from Quito (the capital of Ecuador). -

The southernmost "caga tió" in the world
It is Christmas and we have already prepared what is probably the southernmost "caga tió" in the world -
Minke whale
A minke whale image (Balaenoptera Acutorostrata). There are evidences that whales beached and where a meeting point for yamana families that exploited the remanis. -
Finch (Galápagos Islands)
Darwin did not show as much interest in finches (photo) as he did in San Cristóbal mockingbirds. The males are black and the females have a rather gray plumage. They can be found in all of the Galápagos islands. -
Finches from Galápagos Islands
As he visited different places of the Galápagos Islands, Darwin captured pinches, thinking that they were different varieties of one species, and put them all into one sack: the sack of the Galápagos finches. -
Opuntias, a giant cactuses from the Galápagos Islands
The opuntias are a giant cactuses that look like trees. Their trunk is covered with very dangerous spines. What is the reason for that? The giant tortoises and the land iguanas living in the drier areas of the Galápagos, feed, among other things, on opuntias. Therefore, the way for the opuntia to reach maturity is to survive the repeated attacks of reptiles. Solution: defending itself with a dense battery of spines. -
The trunk of opuntias (Giant cactuses)
The opuntia is a giant cactus. Their trunk is not made of solid wood, as that of a pine or an oak, but a very light mesh that, like the beams of a skyscraper, sets up a lattice structure capable of sustaining heavy weigh over a high top. -
Turtle (Galápagos Islands)
The giant tortoises living in the Galápagos Islands can reach 250 kilos of weigh and live over 150 years. -

Sea lion in the water
a young sea lion defies our researcher, Jordi Serrallonga, to play chase and do flips underwater. The game continues like this until the lion, tired of not having found an opponent worthy of his abilities, leaves with great velocity. -
Sea lion
Sea lions' enjoy playing chase, flipping and blowing bubbles underwater. They are great imitators, and so are we. This proves that we are not alone on this planet. We are not the chosen species but one more species in the midst of all biodiversity. -
Sierra Negra volcano (Galápagos Islands)
Sierra Negra volcano on Isabela Island (Galápagos); the vegetation inside the caldera has disappeared completely under a layer of lava. -

The home-laboratory of Darwin: Down House.
The home-laboratory of Charles Robert Darwin, Down House. Here is where he wrote his great work, The Origin of Species (1859), and also made many of his experiments and studies on plants and animals. -
Detail of the excavation (Tierra del Fuego)
Excavation detail, you can see two ribs and some lithic remains.

Wind effects (Tierra del Fuego)
A Nothofagus with the particular form developed by the wind, what they call a "flag tree".

The curse of Archaeology
The curse of Archaeology never fails: 4 days and we start packing everything. During the final stretch of the excavation, everything appears!. In the image you can see an accumulation of material. Each nail corresponds to an artifact that we must remove; take its position with the total station, introduce it inside a plastic bag with a number, that from now it will be its identification (that will allow us to know from which layer the artifact comes, in which square meter, etc.).

At the site (Tierra del Fuego)
Colleagues at the site. Wodden planks are used so we dont have to work literally on the site. This makes us juggling!
-
Shells at Tierra del Fuego
Shells recovered so they can be analyzed; that way we can determine the specie, the dimensions (if they eat small or big individuals), etc.
