Reptiles require external heat to thermoregulate. If a reptile's temperature gets too low, it will need to find a source of heat to raise its body temperature. In the wild, most reptiles do this by basking in the sun. In captivity, heat lights, heating pad, and other heat sources are provided to allow them to thermoregulate.
The study of distribution of living organism is kow as demography, while studying their fosils is known as paleantology.
The answer to this question is "to put the two groups into the different environment" as a scientist separates a population of fruit flies into two groups and this would increase the rate of speciation in this population. This is the best solution that the scientist could do to increase the rate and get a more reliable result and observations.

Climate is best described as B. THE LONG-TERM AVERAGE OF WEATHER VARIATIONS IN A SPECIFIC AREA.
The long term average being 30 years. These weather variations are affected by the temperature, precipitation, and wind.
Climate determinants include latitude, altitude, proximity to mountains and oceans, proportion of land to water, thermohaline circulation of the ocean, ocean currents, density and type of vegetation present in an area, as well as the areas' water retention and rainfall.
