What is the “genetic toolkit” and how does it constrain evolution? A complete answer will discuss both the incremental changes of form from evolution occurring as well as the lack of extremely large changes in development from an evolutionary perspective.
Genetic toolkit is a small gene subset located within the genome of the organism and these genes helps in controlling the products of the embryonic development within the organism. The genes that are present in the genetic toolkit help in the evolution, developmental biology and play a critical role in understanding of the molecule genetics. These genes are mostly highly conserved genes and they even help in planning the body plan, determining the pattern of the body and help with a wide range of signaling pathways.
The toolkit genes help in evolution as well as put a constraint to the evolution. The common toolkit gene are responsible for evolving the life and help in the phenotypic evolution and diversity. The use of gene toolkit states that evolution uses the same ingredients for developing in an organism and it helps in expressing the genes at different times or different combination depending upon the requirement. The small number of genes can lead to a number of diverse types of phenotypes and the conserved gene within the genomic toolkit can bring about large number of gene rearrangement and hence it can lead to a number of evolved attributes.
