Genes are inherited, but how about the environment? Children inherit many things from their parents, not only genes. New scientific results show that what a parent leaves to its children is important generally in evolution---and has implications for human survival in the future.
Scientists at the New England Complex Systems Institute (NECSI) recently determined that current models of evolution are inadequate since they do not accurately account for how organisms interact with their environment. Published in the journal Complexity, the study introduces a new evolutionary concept to describe this interaction: environmental inheritance. (From Press Release)
Abstract
We review recent research which reveals: (1) how spatially distributed populations avoid
overexploiting resources due to the local extinction of over-exploitative variants, and (2)
how the
conventional understanding of evolutionary processes is violated by
spatial
populations so that basic concepts, including fitness
assignment to individual organisms,
are not applicable, and even kin
and group selection are unable to describe the
mechanism by which
exploitative behavior is bounded. To understand these evolutionary
processes a broader view is needed of the properties of multiscale
spatiotemporal patterns
in organism-environment interactions. We
discuss measures that quantify the effects of
these interactions on
the evolution of a population, including multi-generational fitness
and the heritability of the environment.
