Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Two related species of salamanders were found living on opposite sides of a mountain. One species lives in along a shady forest stream on the leaf covered-ground and is brown with dark green spots. The other species live along the bright, sandy banks of a larger river is light tan in color. What is most likely cause of the diffrences between these two speces of salamander?
A
Different habtats
B
Mating seasons
C
Predatation
D
Competiton
Explanation: 

Detailed explanation-1: -Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.

Detailed explanation-2: -Given that two unrelated species that share similar niches on different continents are formed, convergent evolution occurs as two different and unrelated organisms independently evolved the same traits.

Detailed explanation-3: -The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Detailed explanation-4: -survival of the fittest, term made famous in the fifth edition (published in 1869) of On the Origin of Species by British naturalist Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing.
