Which way is evolution headed? For a long time, scientists have resisted
stating that evolution follows an “ascending” path. This is the reason why
authors such as Richard Dawkins or Stephen J. Gould, so confronted in other
matters, agree in comparing evolution to an erratic and random path.
The biologist Ambrosio García Leal makes a
critical contribution to this crucial mystery with the notion of the “bomb of
complexity”, which promotes phenotypic plasticity – or the capacity to modify physiology,
anatomy or behavior according to environmental
requirements – and explains why organisms seem to distance themselves more and
more from minimum complexity and how they manage to successfully face unpredictable
environments. He also introduces a new concept of Darwinist individuality, compatible
with the integration of individuals in cooperative associations that are
susceptible to being favored by natural selection.
Sex and the capacity to learn play a fundamental role in becoming independent
from environmental uncertainty.
Ambrosio García Leal (Barbate, 1958) is a biologist. He has a doctorate degree in the
Philosophy of Science from the UAB and has done research in the fields of
ecology, biothermodynamics and the theory of complex adaptive
systems. In recent years, his interests have derived towards the philosophy of
biology and the evolution of sex in Darwinist theory. He has worked closely for
years with the Metatemas collection in Tusquets Editores and has collaborated as a scientific consultant at
CosmoCaixa. He has written the books La conjura de los
machos (A Confederacy of Males)
and El sexo de las lagartijas (The Sex of Lizards), both published by
Tusquets Editores.
