In this paper, we extend the ecological scaffolding model of evolutionary transitions in individuality by proposing a mechanism of endogenization that brings us a step closer to understanding the emergence of genuine collective-level individuals.

Finally, I show how their framework can be deployed in the context of evolutionary transition in individuality to assess when a transition has occurred.

Second, all the measures they propose are correlational. I propose instead a causal one.

First, I argue that some of the measures they propose are more adequate than others.

New paper on the concept of individuality in EJPS. In this paper, I start from the information-theoretic measures of individuality proposed by Krakauer et al. and do three things:.

We provide an example based on our recent work on scaffolding endogenization ([), showing how shifting from an internalist to an externalist perspective changes the focus from altruism to collective-level stability in different environments.

Evolutionary transitions in individuality (ETIs), such as the emergence of multicellularity, are events in the history of life during which entities at one level of organisation (particles) form...

Internalist and externalist explanations should not be seen as opposing, but rather as complementary. Each provides a unique perspective on the world and is better suited to answer certain questions.

According to this framework, what kickstarts an ETI are environmental factors providing sufficient conditions for the three conditions to be met. An example of this process is hydrothermal vents that might have provided the template for cell walls.

A different mode of explanation is offered by the ecological scaffolding framework, as discussed in several papers (see for example [ and [).
