Biological evolution simply put is descent with modification. This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life.

Biological evolution is not simply a matter of change over time. Lots of things change over time: trees lose their leaves, mountain ranges rise and erode, but they aren’t examples of biological evolution because they don’t involve descent through genetic inheritance.
The central idea of biological evolution is that all life on Earth shares a common ancestor, just as you and your cousins share a common grandmother.
Through the process of descent with modification, the common ancestor of life on Earth gave rise to the fantastic diversity that we see…

Read the new volume of Archeological Papers of the American Anthropological Association on “inalienable wealth” in AnthroSource!
“Inalienable possessions,” as conceptualized by Annette Weiner (1985, 1992), are objects imbued with meaning and value based on the social identity of the original and subsequent owners. They maintain attachment to their owner- even when passed to other individuals- although this attachment may not always be physical. These objects also contain embedded histories and knowledge and legitimate identity and authority. According to Weiner (1985):
The primary value of inalienability, however, is expressed through the power these objects have to define who one is in an historical sense. The object acts as a vehicle for bringing past time into the present, so that the histories of ancestors, titles, or mythological events become an intimate part of a person’s present identity. To lose this claim to the past is to lose part of who…

Este es un magnífico ejemplo de arquitectura que se va a perder para siempre. Se tratan de rediles de alta montaña en la zona de Eraul (Navarra), que actualmente se encuentran en ruina avanzada.
In the last few weeks this blog has been a little bit quieter than usual and now the reason for this can be seen on the net: blogging archaeology is out!
Thanks to Dougs and Chris´ invitation I wrote an article called “Why archaeological blogging matters: personal experiences from Central Europe and South America” for their online publication “Blogging Archaeology”, based on an earlier draft on “What are the goals of archaeological blogging?“. The book has been presented officially on Saturday at the session “Archaeological Blogging” at the SAA in Austin, Texas. It consists of different contributions, from rather scholarly papers to personal experiences, but what unites us is the belief that blogging archaeology, in all its different versions, is relevant to our discipline, the public and to all of us who wish to promote archaeology to an ever wider audience, using the web and social media.
I am very…
