From a more general evolutionary standpoint, these results are consistent with the notion that neutral mutations provide essential material for subsequent evolutionary innovation [ 28- 31].
The newly established gene expression pattern at the irreversible stage may provide essential material basis for a new set of interactions of molecules, which support the stable malignant phenotypes of the transformed cells.

Matthew Lawson, Head of Library and Learner Development at the university, said the scheme will provide "essential learning materials to support studies".
Experiments in fission reactors are able to provide essential data on materials radiation properties; tritium release, inventory and permeation; and thermomechanical behavior of the blanket breeder/multiplier.
UNICEF and partners also provide essential teaching and learning materials, as well as the training of teachers and staff.
Furthermore, assistance is needed to ensure adequate water and sanitation facilities and provide essential teaching and learning materials for children and teachers.
