Assumptions about communicating with aliens and evolution of mobile animals

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - A new study is causing scientists to re-think the events that led to the end of a Snowball Earth ice age some 600 million years ago. See article.
g Life - New research shows that mobile animals may have evolved much earlier than previously thought. See article.
g Message - Communicating with Aliens, Part I: The SETI debates have included cautionary arguments about the possibility that aliens might be hostile. But this perspective, most easily dealt with by military attitudes, tends to be set aside in favor of an assumption that aliens would necessarily be intelligent and motivated to communicate in a way that fits comfortably into Western assumptions — to the point of commercializing the dispatch of personal messages into deep space at a charge of $14.95 each. Unfortunately the assumptions associated with this process do not seem to have been explored. Reliance on number theory as a basis for developing communication could easily be interpreted as a convenient projection by a psycho-socially unchallenged scientific milieu — which has its own internal communication problems between disciplines for which no common language has yet been developed. The nature of the challenge can perhaps best be scoped out by exploring the difficulties of communicating with the "aliens" that are frequently encountered in the daily life of a global society.
