Thinking about super-dominant populations of native species – Examples from Brazil

Thinking about bacterial populations as multicellular organisms.

It has been a decade since multicellularity was proposed as a general bacterial trait. Intercellular communication and multicellular coordination are now known to be widespread among prokaryotes and to affect multiple phenotypes. Many different classes of signaling molecules have been identified in both Gram-positive and Gram-negative species. Bacteria have sophisticated signal transduction net...

Thinking about populations and races in time.

Biologists and philosophers have offered differing concepts of biological race. That is, they have offered different candidates for what a biological correlate of race might be; for example, races might be subspecies, clades, lineages, ecotypes, or genetic clusters. One thing that is striking about each of these proposals is that they all depend on a concept of population. Indeed, some authors ...

Thinking slow about thinking fast

In his book, Thinking, Fast and Slow, Daniel Kahneman attributes experientially-learned real-world coping skills to an " associative machine " acting on declarative memories of facts and events. While this attribution is probably correct for the unfamiliar types of situations that are the subject of his famous experiments conducted with Amos Tversky, we argue that experientially-learned real-wo...

We propose as a working hypothesis a Separability Hypothesis which posits that we can factor off an architecture for cognition from a more general architecture for mind, thus avoiding a number of philosophical objections that have been raised about the "Strong AI" hypothesis. We the...
