Desert landforms developed synchronously in the southern and northern UBD after the paleolake regressed.
According to the first panel of Figure 2, false locations and correct locations developed synchronously in the early stage (from 0 to 300 minutes) of the competition, but diverged eventually.
If fore- and hindlimbs developed synchronously, there would be 10 'simultaneous' event-pair scores (one for every pair of serially homologous events, each scoring 1) and 45 scores each of 'before' (scoring 0) and 'after' (scoring 2).
However, two independent unilateral primary tumors can develop synchronously and contralateral tumor spread can occur.
Supported by the concept of "field carcinogenesis" [ 2], cancer may develop synchronously or metachronously in the UADT.
Zygotes develop synchronously during the first division cycle, completed about 24 h after fertilization (AF) with an invariant, asymmetric cell division [ 4].
Indeed, a high similarity of allelic imbalances has been seen in simultaneously developing breast cancers in monozygotic twins, and allelotypes of CBCs developing synchronously were found to be more alike than metachronous CBCs [ 7, 15].
In contrast to some other animal models, in which the arthritic response develops gradually and unpredictably, in this model the flare response develops synchronously, allowing precise analysis of pathophysiological mechanisms [ 4, 5].
As all flowers of an individual plant do not develop synchronously, it is very likely that insects transfer pollen from late flowers to stigmata of early flowers of the same plant (i.e., geitonogamy).
Moreover, we find that the first seven pairs of dorsoventral muscles develop synchronously in Wirenia, similar to juvenile polyplacophorans [ 7], which supports the conclusions based on the seven-shelled Kulindroplax.
Based on these findings we conclude that synchronous unilateral tumors often are genetically similar, indicating that they develop from a single clonal origin, but multiple individual primary carcinomas might also develop synchronously in the same breast, confirming earlier studies [ 8, 16, 19, 36].
