Of course, we love it, it makes us joyful or transports us into tears, rapture and dance, but it bears no obvious, tangible evolutionary advantage.
The resolution of the condition that is hypothesized to stimulate the hiccup should offer a tangible evolutionary advantage.
To answer such claims, some tangible fossil evidence of fundamental evolutionary change from deep within the history of life on this planet is described in the next section.
Recently, Smith (e.g., Smith 2011a 2011b) situated these behaviours within an evolutionary framework that views tangible management practices as aspects of niche construction.
Assays of individual functions and whole-organism fitness are clearly quite different, but it is the latter, poorly measured property that ultimately determines both evolutionary success and the tangible dimensions of the niche.
However, inconsistencies between SINE-based results and other molecular data may occur and are tangible evidence of complex speciation events, revealing dynamic evolutionary histories.
Even with the use of RGCs, resolving the relationship between the supergroups remains an enormously difficult task, so perhaps, the most tangible outcome of this analysis is the rejection of certain evolutionary hypotheses.
This idea is known as group selection, and it's an explanation that most evolutionary biologists now dismiss, because the advantages of generosity are much less tangible than the benefits of selfishness.
The study by Karban and Shiojiri (2009) demonstrated a tangible benefit for plants interacting with kin versus non-kin plants, indicating a clear evolutionary trade-off in plant kin selection.
From a mystical perspective, it becomes apparent that what you are awakening to in such moments is the tangible, felt, human experience of the energy and intelligence that created the universe, that catalyzed the evolutionary process and that is driving it right now.
Traditionally, those are the areas where evolutionary biology's greatest weaknesses have been when it comes to providing a fully tangible account of life's history.
