Round 2. White blocks a Clarke takedown attempt and lands a looping counterpunch. Clarke clinches and White hammers him with a series of heavy punches from close range. It's rare you see such power generated from that position. White then drops Clarke with a knee to the body. White lets Clarke stand back up. White follows with huge punches to a now bloodied Clarke. Clarke is forced to simply back up. White drops Clarke with a punch and has Clarke stand up. Clarke grabs a single leg but eats further punches and elbows in the attempt. White drops Clarke again late and finally the fight is called off.
The functionality of an external battery pack comes at a cost. In short, you have to remember to charge it and bring the right cables. Unlike a battery case for your phone, which you most likely charge every evening next to your bed, an external battery pack just sits in your bag, patiently waiting for you to remember it exists. Usually that happens when it’s on its last legs, right before it becomes a hunk of useless lithium-ion cells. There’s no worse feeling than pulling out your battery pack during a desperate situation only to find it dead as a doornail.
In practice, there are two bodies of evolutionary theory that exist in parallel, traditional population genetics operating in the genotype space and the biometric theory used in plant and animal breeding , operating in phenotype space. The missing part is the mapping between the genotype and phenotype space. This leads to a "sleight of hand" (as Lewontin terms it) whereby variables in the equations of one domain, are considered parameters or constants , where, in a full-treatment they would be transformed themselves by the evolutionary process and are in reality functions of the state variables in the other domain. The "sleight of hand" is assuming that we know this mapping. Proceeding as if we do understand it is enough to analyze many cases of interest. For example, if the phenotype is almost one-to-one with genotype ( sickle-cell disease ) or the time-scale is sufficiently short, the "constants" can be treated as such; however, there are many situations where it is inaccurate.
