The phrase "an old event" is correct and usable in written English.
You can use it to refer to an occurrence or happening that took place a long time ago.
Example: "The museum is hosting a special exhibit that focuses on an old event from our town's history."
Alternatives: "a past event" or "a historical event".
The second version (with "match=none" and "aspect=@aspectfiles") is helpful when you need to fix an old event list which was processed with a bad aspect solution, and you have somehow obtained (or hacked together) a new aspect solution file.
Phylogenetic analyses (Fig. 1 and Figure S1) show that MT4 resulted from an old event of duplication and the high degree of sequence conservation between human and mouse orthologues strongly points to a role which seems to have been functionally important in mammalian evolution.
During remote autobiographical retrieval, hippocampal activity could be related to the construction of a new memory for an old event, or to the retrieval of the original memory or its more recent reconstructions.
The significantly negative HKA P value obtained for the total sample set together with the low subspecies differentiation indicated by FST and the low frequencies of NSyn variants is suggestive of a signature of an old event of purifying selection in WFDC6 and EPPIN in P. troglodytes.
It's the cub of an older event, The Yacht Week, brainchild of a bunch of young, London-based Swedish friends, which in its 11 seasons has grown meteorically, now setting sail 39 times a year.
Taken together, these results suggest that introgression of archaic lineages occurred at two different times and places: an older event in East Asia involving migrants from the first Out-of-Africa migration and a more recent event in the Middle East before dispersal of migrants from the second Out-of-Africa migration into the Caucasus, Europe, and south Asia.
They suggested that an older event around 1050 1259 AD and the younger event around 1259 1433 AD (Rajendran et al. 2015).
First, contiguous range expansion was predicted for cladogram A in the highest nesting level (5-1, 5-2), which represents an older event in the evolutionary history of P. nigromaculata.
The method we adopted allowed us to exclude that the relative low amount of divergence can be attributed to an older event of splitting followed by moderate gene flow.
Because it has been established that a variant type of acetylcholinesterase provides resistance to organophosphates in lice [ 20], it is possible that the high values of FST among sampling sites and the weak signal the of selective sweep reported on LG14 are due to an older event of selection for lice resistant to organophosphates.
In conclusion, the scientists hypothesize that the S-opsin loss is likely a phylogenetically old event, occurring early in marine mammal evolution.
