To put it another way, a delicate homeothermy could have been maintained alongside a weak endothermy (internal energy expenditure).
Furthermore, maintenance of homeothermy during this transition period strongly supports the well being of lambs, however, failing of this may lead to increase mortality rate (Dwyer, 2008).
Other questions might come up that are harder to answer, such as when homeothermy and ZW sex determination evolved in the ancestry of birds.
The afternoon is characterized by higher solar radiation when sheep require the employment of more intensively mechanisms for heat dissipation to maintain homeothermy (BAETA; SOUSA, 2010).
1993); (2) homeothermy (stable body temperature) and increased metabolic efficiency (Heinrich 1977; Avery 1979); (3) homeothermy followed by decreasing body size (McNab 1978); (4) postural changes that enhance exercise performance (Heath 1968, cf.
Perhaps higher concentration of melatonin is required to combat the stressful condition in order to maintain the homeothermy.
Given the long time period apparently involved in the evolution of endothermy, it is unlikely that homeothermy was a significant selective factor in this process.
