He wonders if there are buried microbial communities much older than 11 million years, and whether any of them hide other markers of complex ecology, such as viruses.
The invention of projectile weapons was long believed to be one of the major markers of complex and advanced behavior that set Homo sapiens apart from earlier hominids.
Additionally, whether the identified biomarkers are useful as accurate, quantitative markers of complex human diseases is still unknown.

Medication overuse seems to be either a marker of a complex chronic headache requiring increased support from the health services or causally associated with a worsening of the headache.
Therefore, we hypothesize PRL rather as a marker of the complex multi-level alterations involved in the onset and progression of T2DM.
Data from paragangliomas and pheochromocytomas suggested that negative staining for SDHB was a marker of mitochondrial complex II dysfunction, and this was regardless of which protein was disrupted.
This suggests that the frequently used measure of economic position (GDP per capita) may not be the best marker of the complex characteristics which affect infant mortality.
We quantified H2S, which is produced by the anaerobic decomposition of fecal waste, as a marker of this complex mixture that is related to hog odor intensity (Wing et al. 2008b; Schiffman et al. 2005).
Our findings should not be interpreted as meaning that NO2 is a causal factor; it is more likely a marker of the complex mixture that is derived from combustion (Goldberg 2007).
