Community tennis courts still exist as a legacy of the mid-20th century boom in the sport, but few new ones are being built and the extant ones are seldom booked up.
Ibn al-Imâm (Avempace 1968, 177 178) produced the first list of Avempace's writings, followed by Ibn Abû Uṣaybi‛a (1886, 2001), and the extant ones are found in the manuscripts Escorial, Derenbourg 612, Oxford, Pococke 206, Berlin, Ahlwardt, 5060 (now Krakow), and Tashkent 2385.
ADMINISTERING such a prodigious inventory — tending to requests from impending friends, let alone communicating with extant ones — is strenuous.
Covered bridges were also built over the Petitcodiac River, the final extant one being "Hasty", built in 1929.
Though sexual reproduction and genetic recombinations are a source of combinative variation in populations, they do not produce new alleles but only new combinations of the extant ones, which are, moreover, doomed to be destroyed in the next generation.
Frequently however, the goal is to understand the energy expenditure of extinct creatures or extant ones that are not amenable to laboratory experiments.
If these arguments only excluded the root from all extant archaea one is left wondering why all archaea that are not clearly derived went extinct.
But I was NOT discussing the first organisms, whose nature cannot be rigorously deduced by cladistic comparisons of extant organisms, but the last common ancestor of all extant ones (cenancestor), which was much more complex and at least somewhat more recent, and whose general nature can in principle be determined by a combination of cladistic and transition analyses of extant lineages.
The results, published Wednesday in PLOS One, are based on newly discovered fossils and comparisons to extant relatives.
Nonetheless, if you need to upgrade your present car, are about to have your first child or are booting the extant ones off to college and need to replace the current machine because it's ill-matched to your new lifestyle or you want a new toy now's the time.
Here, for the first time, we demonstrate that conifer nupts can be PCR amplified using our approach and that ancestral plastomic characteristics retained in nupts can be compared with extant ones, providing valuable information for understanding plastome evolution in conifers.
