Bacteria is not as complex as human and other animal lives, which means they need less energy and DNA to evolve in these ways.
The baby is considered as extremely preterm infant.
The babies that are born alive before the completion of a period of 37 weeks of pregnancy are the preterm babies. There are three categories into which preterm born babies are distinguished: moderate to late preterm for 32-37 weeks, very preterm for 28-32 weeks and extremely preterm for less than 28 weeks.
Premature births are one of the major causes of death of children under the age of 5 years. The babies that survive may have problems and may be visual or hearing impaired, may have learning disabilities etc.
