Question

House sparrows in the northern part of North America are larger than those found in the southern regions. Which mechanism of microevolution is more likely to be responsible for this?

Answer 1

House sparrows in the northern part of North America are larger than those found in the southern regions. This is most likely to be the NATURAL SELECTION mechanism of microevolution.

Natural Selection is a process that occurs over a period of time wherein a certain organism’s traits make them more likely to survive.
