Perplexed by a practice that seemed to worsen an already grave health condition, Le powski reviewed the medical literature and found a report indicating t hat refeeding p rograms in East Africa famine relief camps were correlated with outb reaks of malaria. Based on this finding, Lepowski suggested that starving children d uring bouts of ma laria is an adaptive practice to protect them from the malaria par asite. What is m eant by the term “adaptation” in this context? What are the strengt hs and limitation s of this adaptive explanation? Are there reasonable alternatives to an adaptive exp lanation?

LITERATURE AND LANGUAGE
According to the context, adaptation is defined as a phenotypic variant with the highest reproductive success in a given environment, among a set of variants that is well specified Adaptation can be defined as features that enable an organism to survive and reproduce better in the environment it lives. Adaptation is the good fit of organisms in the environment they live. With different causes, it can occur at three levels of the hierarchy (Gould, 1979).Adaptation according to physiologists can also be termed as the phenotypic plasticity which allows organisms to mould their form during ontogeny, to prevailing circumstances. While human adaptations to high attitude are classified in this category, resistance to sick ling heterozygote to malaria, are considered genetic and Darwinian.
Strengths and limitations of the adaptive process include; it only refers mostly to the features and not to the genotypes of the specific loci. This is owed to the fact that a variety of genotypes can produce any given phenotype. Furthermore, it is only defining the explicit alternatives because the exact phenotype under question determines the flexibility of the choice of the set of alternatives. The above adaptation does not require the demonstration of a mechanism of evolutionary change or a specific historical process (Gould, 1979).
Alternatives for the adaptation explanation include fitness, set of phenotypes and environmental context.
Fitness is mostly measured through the success of reproduction. This can either be done over a reproductive episode or over a long period of time. As you are doing this, put into consideration the effects of a certain trait to an individual’s genetic relatives. Other than progeny, grand progeny can also be counted (Gould, 1979). In answering different questions of reproductive success, measurement can be done using both short and long term. For effective short term measures of reproductive success, a good relation with the long time measures must be positively maintained. A genotype with greater fitness is one that increases in frequency in the next generation when compared to other genotypes in the same population all factors being equal. Most of the time, it is much easier to isolate the effects of variations brought about by phenotypes on different fitn...
