Sentence examples for been conserved for over from inspiring English sources
The four silk genes have been conserved for over 150 million years in all investigated bee, ant and hornet species, implying a distinct functional role for each protein.
In the present study the goal was to determine whether all of the four related coiled coil silk proteins, which have been conserved for over 150 million years, are essential to silk material function.
It is therefore likely that the four paralogous coiled coil silk genes have been conserved for over 150 million years in social Hymenopteran lineages due to their protein products playing a critical role in the process of natural silk fabrication, rather than in conferring properties to the end product.

These suggest that the need to modulate both syntrophin stoichiometry and the presence of the ancestral dystrophin C-terminus are vertebrate-wide, necessitating mechanisms that have been conserved for over 500 million years.
If our conclusion that the rodent and primate CD94L molecules derived from a common ancestor is correct, and the antigen presenting function of these molecule has been conserved for over 50 million years, then we predict that their PBR residues would show signs of negative selective pressure.
