angle of incoming sunlight
Explanation:
The single feature that primarily determines the variation in climate in different parts of the world is the angle of incoming sunlight. 
- Climate is simply an extended study of weather over a long period of time. 
- The elements of weather like temperature, pressure, rainfall all conditions climate. 
- The angle of incoming sunlight is by far the most important factor that determines climatic patterns on the earth. 
- Around the equator, the sun is overhead and these regions are usually hot driving a wide range of weather phenomenon. 
- The polar and temperate regions receive diffused sunlight because the sun is at an angle there.

Answer:
The emergence of new species from surviving ancestral species and both species continue to interact during a transition period is known as Sympatric Speciation.
Explanation:
Hybrid Zone is the  area where two species continue to interact. Hybrid offspring are produced by two different species.
1) hybrid offspring
2) zones
3) reinforces 
4) zones 
5) Slow down
6) gradual speciation model 
7) punctuated equilibrium
