For the two ancestral nodes reconstructed, a weighted sampling of 10,000 sequences from the posterior distribution resulted in ancestral sequences that were either identical (parrot/passerine ancestor, 100% identical), or highly similar to (passerine ancestor, 83% or 8343 sequences out of 10,000 identical) the most likely ancestral reconstruction.
Here I describe that, prior to founding the eight F populations described above, the identical EM ancestor had actually been evolved in the same methanol minimal medium (populations 'E1-E8') behavedaved quite differently due an unexpected density-dependence for growth.
In order for this to be the case, they must express different sets of genes, so that they produce different proteins despite their identical embryological ancestors.
One species appears to have "suddenly" produced two daughter lineages, one anatomically identical to the ancestor, the other anatomically distinct.
As well as the absence of mutations, errors followed by reversals could result in a descendant genetically identical to their ancestor.
(b) A punctuated pattern in which one lineage appears to have quickly produced two daughter species, one with a form identical to the ancestor and one with a distinct form.
These general conditions were identical to the ancestor LHM population, however because of the complexity of the ML protocol, changes were made in the handling of adults, such that males were crossed (in both C and ML treatments) to virgin females and allowed to interact for 18 h prior to female oviposition.
The sequences of the isolates from the 50°C treatments were identical to the ancestor Anc sequence.
In addition to that, the analysis of all the curricula and textbooks also showed that the way the organisms are presented has the following characteristics: Organisms of every species are presented as absolutely identical to their ancestors.
