Question

Tortoises with long necks were found to be abundant in regions that had vegetation on a higher level. A few years later, drought hit the region and the vegetation dried up over time grasses were observed in the region. Shortly thereafter, an increase in short necked tortoises was observed in the region what does this change in the species of tortoises suggest?

A. Changes in the environment give rise to evolution of species
B. Tortoises all around the world are now short necked
C. Taurus is found only in this region are short necked
D. Only changes and food availability affect the evolution of species

Answer 2

The correct answer is A. Changes in the environment give rise to evolution of species

Step-by-step explanation:

In biology, the word evolution refers to the process in which animal and plant species change over generations, especially as a result of natural selection in which characteristics that help individuals to survive and reproduce prevail over neutral characteristics or characteristics that do not support survival. This occurs in the case presented as a change in the environment that modifies the level at which vegetation is placed leads to the evolution or changes in the length of tortoise that have long necks if the vegetation is in a higher level but later this trait is lost as the vegetation dried, which means this case suggest changes in the environment lead to changes in the characteristics of species or that changes in the environment give rise to evolution of species .
