In most cases, gravitational and non-gravitational torques cause asteroid spin axis orientations to vary widely over short (⩽1 My) timescales.
If there were a characteristic recovery timescale of order 62 My, and random events lowering biodiversity, this could easily produce a periodicity such as observed.
"With my metatarsal I knew exactly what kind of time scale I'd be out for but with my heel there isn't a timescale, there isn't really a cure.
We applied all together six weeks ago and I received mine within three weeks and my son's in the same timescale.
Direct studies of interspecific hybrids of African cichlids (Stelkens et al. 2010) show that postzygotic isolation typically arises over a timescale of ∼ 4 − 18 MY, which corresponds to ∼ 1 − 6 million generations, assuming a generation time of 3 years (Nagl et al. 1998), which suggests the mechanism we present is roughly consistent with empirical data.
The importance of gene duplication is indicated by its frequency: for eukaryotes, it has been estimated that fully 50% of genes are expected to duplicate at least once in timescales of the order of 35 350 My (Lynch and Conery 2000).
I am receiving personalisation funds ergo my fine motor skills (which help with paperwork, amongst other things) are severely compromised ergo I have great difficulty in doing things which to anyone else without my limitations could manage within the council's timescale.
I have asked Nationwide if it would be possible to contact me first and only block my account if there is no confirmation, within an agreed timescale, but all I get is the mindlessly repeated mantra that "security is our number one priority".
During these periods, the birth rates of mammalian LTR element families averaged 276 (85), again on a timescale of 1% LTR sequence divergence (equivalent to ∼0.3 1.0 My for the taxa involved) (table 1).
