Units of interaction, evolution, and replication: organic and behavioral parallels.
Skills live on through neural copies, not just good teaching plans.
01Research in Context
What this study did
Lalli et al. (1995) wrote a theory paper. They asked: what carries behavior forward across people and time?
They compared biology to behavior. Genes copy themselves. The team said the nervous system copies behavior the same way.
What they found
The authors claim the brain is the unit that keeps and copies behavior. Like DNA keeps eye color, neural paths keep how we act.
They call this behavioral lineage. Skills pass from one person to the next through neural imprinting.
How this fits with other research
Hake (1982) came first. That paper told researchers to study human social and verbal behavior, not just rats. Lalli et al. (1995) answered by showing how those human behaviors could survive across generations.
Jensen et al. (2013) extended the idea. They used math from information theory to measure the link between behavior and outcome. This gives numbers to the copying process Lalli et al. (1995) only described.
Lindsley (1996) seems to clash. He said fluency is just fast response chains, no neural copy needed. The papers differ in level: R looks at single-session speed, S et al. look at lifetime transfer. Both can be true.
Why it matters
When you teach a skill, think about the neural copy. Ask: will this learner’s brain hold the response and pass it on? Use clear models, peer tutoring, and repeated practice to strengthen the neural lineage. If the skill survives only in your session, the copy failed.

03Original abstract
Organic and behavioral evolution both involve variation, selection, and replication with retention; but the individuals involved in these processes differ in the two kinds of evolution. In this paper, biological units of evolution, selection, and retention are compared with analogous units at the behavioral level. In organic evolution, natural selection operates on variations among organisms within a species, with the result of preserving in future generations of organisms those heritable characteristics that contributed to the organism's survival and reproduction. Species evolve as characteristics of the population change as a result of past selection. Continuity in a lineage in the biosphere is maintained by replication of genes with retention of organismic characteristics across successive generations of organisms. In behavioral evolution, reinforcement operates on variations among responses within an operant, with the result of preserving in future responses those characteristics that resulted in reinforcement. Continuity in a behavioral lineage, within the repertoire of a given organism, appears to involve retention and replication, but the unit of retention and replication is unknown. We suggest that the locus of retention and replication is the nervous system of the behaving organism.
