Which variable is likely to undergo the largest change
The ermine (Mustela erminea), also known as the stoat or short-tailed weasel, is a mustelid native to Eurasia and North America. It is classified as Least Concern on the IUCN Red List due to its broad circumpolar distribution. 1st
The stoat was introduced to New Zealand in the late 1800s to combat rabbits, but it has wreaked havoc on native bird populations. It was named one of the top 100 “worst invaders” in the world. [three]
Mustela palerminea, a common carnivore in central and eastern Europe during the Middle Pleistocene who spread to North America during the late Blancan or early Irvingtonian, was the stoat’s direct ancestor.
[eight] The stoat is the product of a 5–7 million-year-old phase in which northern forests were replaced by open grassland, resulting in an explosion of small, burrowing rodents. The stoat’s ancestors were larger than the current type, and as they exploited the new food supply, they shrank in size. The stoat appeared in Eurasia shortly after its North American counterpart, the long-tailed weasel, did 2 million years ago. The stoat thrived during the Ice Age because of its small size and long body, which allowed it to hunt in burrows and work under snow. The stoat and the long-tailed weasel were separated until the Bering land bridge was uncovered by dropping sea levels 500,000 years ago. [nine]

Which statement about variation is true
P. lotor is a medium-sized carnivore that has the widest distribution of the Procyonidae family.
Which type of selection tends to increase genetic variation?
Because of its opportunism and adaptability, it can eat anything and has a broad ecological niche with few natural predators.
The evolutionary effects of genetic drift are greatest when
Furthermore, P. lotor possesses physical and physiological characteristics that allow it to colonize a diverse range of ecosystems and climates.
It has continued to extend its native North American range northward, passing through southern Canadian provinces as well as arid areas of the southwestern United States.
Which is a true statement concerning genetic variation
When the conditions are right, colonization can happen quickly after an introduction.
Which of the following statements about genetic variation is true
The species has been introduced to several islands off the coasts of Canada and Alaska, as well as the Caribbean, and in some cases is considered invasive. Following introductions in Western Europe and Japan, it is widening its range as an alien species. Further deliberate foreign introductions are unlikely; however, the species could be inadvertently introduced (it is popular in the pet trade) or by range expansion.
