Snapping shrimp used to be able to swim from the Atlantic Ocean to the Pacific Ocean by traveling between North and South America
Answers
Answer:
b. allopatric speciation
Explanation:
Snapping shrimp used to be able to swim from the Atlantic Ocean to the Pacific Ocean by traveling between North and South America. However, when the Isthmus of Panama appeared (a land bridge that connects the Americas), the shrimp could no longer travel between the oceans and evolved into different species. This is an example of:
a. Sympatric speciation.
b. Allopatric speciation.
c. Punctuated speciation.
d. Genetic drift.
Geographical Barrier:
The barrier that physically segregates and isolates the species population of an area to breed together (interbreeding) is called the geographical barrier. Examples of geographical barriers are mountain building, rivers, and canyons.
Answer and Explanation: 1
The geographic speciation that separates two groups of biological organisms or divided due to geological events like physical barriers or waterways is called allopatric speciation. The peripatric and vicariance models are classified as two different types of subdivisions of allopatric speciation. The glaciers, water bodies, islands, and mountains are categorized as various geographical changes occurring in allopatric speciation.
Therefore, the correct option is b (Allopatric speciation) .
The divergence causing the species population of spanning shrimp to get separated due to the rise of geological events, such as the Isthmus of Panama, is an example of allopatric speciation.
