It is therefore possible that many of the genes giving uncertain phylogenies are consistent with vertical inheritance, but the phylogenetic signal is too weak to give a clear-cut tree.
We know that when you clear cut all the trees and vegetation, then get rid of the top soil and bury the natural course of the streams there is nothing there to hold or guide the water.
The mixed prokaryotic eukaryotic branching pattern of the remaining 49 (6.9%) trees did not enable a clear cut rooting and classification of the trees into one of the above categories (fig. 1 d ).
Food supplies were requisitioned, yet food production was crippled; women, as always, bore the brunt of sowing and harvesting, but, in the absence of men to cut trees and clear new land, farm plots were worked to exhaustion.
To minimise data duplication, they suggested that, where no clear cut choice for a single tree presents itself for a given independent character set (e.g. a particular gene), MRP 'mini-supertrees' of all non-independent source trees based on that character set should be created.
Tree planting in plantations, while lumber companies continue to clear cut existing forestland, is problematic.
Hence, changes in the images before and after trees have been cut are not as obvious as when an area has been clear cut.
Our results are clear cut.
Their position is clear cut.
