Show answer

Answer: (A) Andaman Islands

Answer: (a) Andaman Islands

Scientists at the Botanical Survey of India discovered this new banana species in the tropical rain forests of Little Andaman Islands.

It is about 11 metres tall (usual bananas are 3-4 metres) with unique orange-coloured fruit pulp.

Why Andaman?

These islands are a biodiversity hotspot with dense, largely unexplored tropical rain forests where new species are regularly discovered.

Why not others?

  • (b) Anaimalai Forests (Western Ghats)
  • (c) Maikala Hills (central India)
  • (d) NE tropical forests

This particular species was found in Andaman.

Why this was asked

The Andaman and Nicobar Islands are a biodiversity hotspot where new species are regularly discovered due to their isolated location and unexplored tropical rainforests.

This specific banana species discovery by the Botanical Survey of India was likely a current affairs topic around 2015-16, making it relevant for that year's exam.

UPSC is testing knowledge of India's biodiversity hotspots and which regions are most likely to yield new species discoveries.

Andaman & Nicobar Islands: Biodiversity Hotspot & Endemic Species

Must know

Andaman & Nicobar Islands are a biodiversity hotspot with high endemism

Little Andaman specifically discovered the 11-meter tall banana with orange pulp

Good to know

Islands have largely unexplored tropical rainforests ideal for new species discovery

Botanical Survey of India (BSI) conducts species discovery research here

Why Andaman for Discovery

The Andaman & Nicobar Islands are a biodiversity hotspot with dense, largely unexplored tropical rainforests. Geographic isolation has created unique evolutionary conditions perfect for endemic species development.

• High endemism: Many species found nowhere else on Earth
• Unexplored forests: Remote areas still yield new discoveries
• Island biogeography: Isolation drives unique evolution

Exam traps

Don't confuse: Andaman discovery vs Northeast rainforests - this specific banana was found in Little Andaman

Island advantage: Geographic isolation = higher endemism than mainland forests

BSI role: Botanical Survey of India discovers plant species, not Zoological Survey

Banana Species & Diversity

Environment banana plant orange-coloured fruit 11 metres

Banana Species Diversity: Wild vs Cultivated Varieties

Must know

Wild bananas can reach 11 meters vs 3-4 meters for cultivated varieties

Fruit pulp colors vary: yellow, orange, red, purple in wild species

Good to know

Musa genus has ~70 species, mostly wild and inedible

India is part of Southeast Asian origin center for bananas

Wild vs Cultivated

Most people know only cultivated bananas (3-4 meters, yellow fruit), but wild Musa species show remarkable diversity in height, fruit color, and seed content. The Andaman discovery represents this hidden wild diversity.

India's Banana Heritage

Northeast India is part of the Southeast Asian gene center for bananas

Kerala leads commercial cultivation with Robusta and Nendran varieties

Tamil Nadu, Maharashtra are other major producing states

Wild species preservation critical for genetic diversity of commercial crops

Exam traps

Height confusion: Wild bananas (11m) ≠ commercial bananas (3-4m)

Seed presence: Wild bananas have large seeds, cultivated ones are seedless

Edibility assumption: Wild species often inedible despite being 'bananas'
