Soft Inheritance Differences Between Human and Chimp Genomes

Human and chimpanzee genomes are highly similar. Protein coding genes in the two species are usually practically identical. This led to some rather silly conclusions by evolutionists trying to make sense of the evidence that showed their gene-centric view made no sense.

In fact, there are substantial molecular differences between humans and chimps, the differences just aren’t typically in the gene sequences. For instance, there are big differences in the regulation of those genes. And many of those differences are types of soft inheritance, involving not DNA differences but chemical markers influencing gene expression. As one report explains:

They found that the distinct gene expression patterns of the three species can be explained by corresponding changes in genetic and epigenetic regulatory mechanisms that determine when and how a gene's DNA code is transcribed to a messenger RNA (mRNA) molecule.

Dr. Gilad also determined that the epigenetics process known as histone modification also differs in the three species. The presence of histone marks during gene transcription indicates that the process is being prevented or modified.

The human and chimp genomes reveal substantial differences in their gene expression patterns. Those differences are due not only to differences in the DNA regulatory sequences but also to differences in the epigenetic markers.

So soft inheritance falsifies evolution’s expectation that acquired changes are not inherited, and soft inheritance’s origin is not explained by evolution, and now evolution must explain how it constructed different soft inheritance strategies in the human and chimp genomes.
