Answer:
Wheat was first domesticated in Mesopotamia because of a favorable climate and a great diversity of wild grains that led to crossbreeding of seeds.
Explanation:
Mesopotamia ( Western Asia )was the first place of domestication of wheat. The favourable climate of intense sunshine of old Western Asia-kuwait, Iraq,...) favours photosynthesis which ensure food production,
Besides the population of this region with wide grains, on hilly land, ensured cross pollination of these wide seeds grains with wheat varieties leading to hybridization, and selection by natural selection for domestication and eventual evolution.
Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
The concept of continuity relates to historical developments and processes because historians can link the happenings in the past to recent occurrences.
- The concept of continuity simply explains the continuation of a cycle and it shows the connection that exists between historical events.
- Changes take place at different times which are then linked forward and backward in time. Continuity refers to the continuance of themes.
- The concept of continuity is vital as historians are able to link what has occurred earlier to the recent things that are happening. For example, Islam had an influence on African culture and its development.
In conclusion, continuity is important to historians.
