evolution and the nature of its genetic material. In particular, whether the progenote [4] -i.e. a primeval biological ancestor with a still rudimentary genotype-phenotype relationship and a RNA genome made of numerous minichomosomes – evolved into a LUCA still endowed with a RNA genome, or...
One of the fundamental questions in insect evolution is the origin of their wings and primary function of ancestral wing precursors. Recent phylogenomic and comparative morphological studies broadly support a terrestrial ancestor of pterygotes, but an aq
The problem of finding the Lowest Common Ancestor (LCA) of a pair of nodes in a rooted tree has been studied more carefully in the second part of the 20th century and now is fairly basic in algorithmic graph theory. This problem is interesting not only for the tricky algorithms ...
Explain, using examples, why is this so. What is typically used to organize homologous traits into groups that evolved from a single ancestor? A. synteny B. cladistics C. molecular systematics D. comparative anatomy In what model organism was genetic linkage first studied? Who created t...
By simple mathematics, it follows that modern humans share a common ancestor some 300 generations back in time. If one assumes a typical generation time of about 20 years, this places the date of the common ancestor at around 6,000 years before present. But how could this be?!
However, because of their co-evolution from a com- mon metazoan ancestor, the core GRNs of different animal groups often utilize the same regulatory genes. As a result, distinct yet parallel sets of CNEs have become irreversibly associated with the same genes that coor...
Although bees are separated from humans by about 600 million years with a common ancestor that had only a rudimentary nervous system, they still share over 60% of our Genome. Any commonly observed learning principles between bees and humans may be consequently either basal, or may have evolved ...
