What can demography and life history contribute to our understanding of human populations
in both the present and in the past? Many researchers have noted that our species Homo
sapiens appears to have undergone a series of demographic transitions in the past. In your
opinion, what are these transitions and how have these effected mortality patterns in human
populations
Demography is that study of populations of human beings and their changes. It includes the
study of the, structure, size the means the population has been structured .Life history is that
time in which all totally different generations of a species succeeding each
other through means of multiplication live or the means by which living and fossil organisms
evolved.
Humans are known as the very productive" species” world has ever seen. Like weeds, human
populations are quick growing. They additionally move quickly, they need settled habitats from
pole to pole. Overall, the human population has had a pattern of exponential growth
Early Population Growth
Homo sapiens emerged about 0.2m years back in Africa. Early humans lived in tiny populations
of mobile hunters and fruit eaters. They moved out of Africa about 0.4m years past. They
shortly enraptured throughout Europe, parts of Asia, and through Australia. By 10,000 yrs time,
they had reached the us. Through this long period, birth and mortality rates were fairly high. As
a result, population declined. people invented agriculture some 10,000 yrs ago. This provided
a bigger, more sustained food offer . It additionally allowed them stay in villages and cities for

the first time. The death rate inflated owing to diseases related with domesticated animals and
congested living environments. The birth rate increased because there was a lot of food and
settled life gave them other merits. The resultant effect was continued slow population growth.
Demographic Transition
Major changes within the human population initial began throughout the 1700s in Europe and
North America. 1st mortality rates dropped, accompanied later by birth rates.
Death Rates Fall
Scientific and technological advances led to lower death rates in eighteenth century Europe and
North America: New knowledge base of the causing a feeling of unrest led to improved
water provides, sewers, and private hygiene. Better farming techniques and
machines increased the food offer. The Industrial and technological Revolution of the
1800s channeled to new sources of energy, like coal and electricity. This
enhanced the potency of the new agricultural machines. It additionally led to
train transport, that improved the distribution of food offer. For all these reasons, death rates
fell, particularly in youngsters. This allowed more youngsters to survive to
adulthood, therefore birth rates increased. because the gap between fertility and mortality
rates increased, the human growth grew quicker.
Birth Rates Fall
It wasn’t long before birth rates began to fall additionally in Europe and North
America. individuals started having fewer youngsters because massive families
