<em>The process of evolution occurs only in populations and not in individuals... Five forces can cause genetic variation and evolution in a population: mutations, natural selection, genetic drift, genetic hitchhiking, and gene flow.</em>
Look up Dawrin's theory of evolution. Basically, fossil records show how life forms change over time through evolution.
Answer:
10 meters/second.
Explanation:
Unladen swallow consists of two species are <em>Hirundo domicella </em>and the <em>Hirundo spilodera</em>.
The average speed of unladen swallow comes out to be 10 meters/second. The maximum speed can go upto 13-14 meters/second. The speed of unladen swallow can be calculated by the formula given by Graham K. Taylor. According to graham the speed of unladen swallow is 3 times of the product of frequency and amplitude. ( v= 3fA, v is velocity, f is frequency and A is amplitude).
