Mr. Hoelzer:
The Modern Evolutionary Synthesis AKA neo-Darwinism combines Darwin's
theory of the evolution of the species by natural selection with
Mendelian inheritance. Don't you consider that an example of natural
selection transmitting information to gene pools, of natural selection
being linked to inheritance?
The brief article states, "Evolution consists primarily of changes in
the frequencies of alleles between one generation and another as a
result of genetic drift, gene flow and natural selection." I'm astounded
we apparently take opposing views on this matter.

Modern evolutionary synthesis
The modern evolutionary synthesis (often referred to simply as the
modern synthesis)
brings together Charles Darwin's theory of the evolution of species by
natural selection with Gregor Mendel's theory of genetics as the basis
for biological inheritance.The modern evolutionary synthesis (often
referred to simply as the modern synthesis) brings together Charles
Darwin's theory of the evolution of species by natural selection with
Gregor Mendel's theory of genetics as the basis for biological
inheritance. Major figures in the development of the modern synthesis
include Theodosius Dobzhansky, Julian Huxley, Ernst Mayr, and George
Gaylord Simpson.
According to the modern synthesis, genetic variation in populations
arises by chance through mutation (mistakes in DNA replication) and
recombination (crossing over of homologous chromosomes during meiosis).
Evolution consists primarily of changes in the frequencies of alleles
between one generation and another as a result of genetic drift, gene
flow and natural selection. Speciation occurs gradually when populations
are reproductively isolated by geographic barriers.
