Understanding Extinct Animals and Their Native Habitats

This question asks us to match a list of extinct animals with their native regions. Understanding the natural habitats of these animals helps us learn about biodiversity and the impact of extinction.

Let's analyze each animal and its corresponding native region:

• Dodo: The Dodo (Raphus cucullatus) was a flightless bird native to the island of Mauritius. Mauritius is located in the Indian Ocean, east of Madagascar.
• Quagga: The Quagga (Equus quagga quagga) was a subspecies of the plains zebra, native to South Africa. It is now extinct. South Africa is part of the continent of Africa.
• Thylacine: The Thylacine (Thylacinus cynocephalus), also known as the Tasmanian Tiger, was a large carnivorous marsupial native to Australia, Tasmania, and New Guinea. It is widely believed to be extinct.
• Stellar’s Sea Cow: The Stellar’s Sea Cow (Hydrodamalis gigas) was a large, herbivorous marine mammal. It was found in the nearshore areas of the Bering Sea between Alaska and Russia. Specifically, it was native to the Commander Islands, which are part of Russia.

Based on this information, we can create the following matches:

• (A) Dodo matches with (III) Mauritius
• (B) Quagga matches with (IV) Africa (specifically South Africa)
• (C) Thylacine matches with (II) Australia (including Tasmania)
• (D) Stellar’s Sea Cow matches with (I) Russia (Commander Islands)

This gives us the matching pattern: (A)-(III), (B)-(IV), (C)-(II), (D)-(I).

Matching Extinct Animals to Regions

Here is a table summarizing the correct matches:

Comparing this with the given options, the pattern (A)-(III), (B)-(IV), (C)-(II), (D)-(I) corresponds to one of the choices.

Additional Information: Causes of Extinction

The extinction of species like the Dodo, Quagga, Thylacine, and Stellar’s Sea Cow highlights the impact of human activities on biodiversity. Key factors contributing to their extinction include:

• Habitat Loss: Destruction of natural habitats due to human settlement, agriculture, and development.
• Overhunting/Overexploitation: Direct hunting by humans for food, resources, or due to perceived threats (as in the case of the Thylacine). The Stellar's Sea Cow was heavily hunted for its meat, fat, and hide.
• Introduced Species: Arrival of non-native species (like rats, pigs, dogs) brought by humans, which preyed on native animals or competed for resources. This significantly impacted the Dodo and other island species.
• Disease: Introduction of new diseases by humans or introduced animals.
• Climate Change: Long-term shifts in temperature and weather patterns can alter habitats and affect species survival.

Studying these extinct animals and their native regions helps us understand ecological history and the importance of conservation efforts today to prevent further species loss.
