Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
The correct answer is - 1,180 km.
North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Than divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
