Bigger Beaks Through Climate Change | SciShow News

The video discusses how certain bird species and other animals are adapting to climate change by altering their physical features, a phenomenon explained by Allen's Rule. Researchers have observed changes in the size of heat-radiating appendages in various species, correlating with rising temperatures. The video also highlights the conservation efforts for the Kakapo, a flightless parrot in New Zealand, which has shown unexpected genetic resilience despite a population bottleneck. These findings offer hope for the species' future survival.

What is Allen's rule in the context of animal adaptation?

• Animals in colder climates have larger appendages.

• Animals in warmer climates have smaller appendages.

• Warm-blooded animals evolve larger appendages in warmer areas.

• Cold-blooded animals evolve smaller appendages in colder areas.

Which bird species in Australia has shown an increase in bill size due to rising temperatures?

• Sparrow

• Dark-eyed Junco

• Australian Parrot

• Kakapo

What is a significant challenge faced by the Kakapo population despite genetic advantages?

• Increased competition with other species

• Lack of food resources

• Low egg hatching success

• High predation rates

What phenomenon might explain the lower number of harmful mutations in the Kakapo population?

• Genetic drift

• Natural hybridization

• Artificial selection

• Increased genetic diversity

How has the Kakapo population changed since 1995?

• It has become extinct.

• It has increased to about 200 individuals.

• It has decreased significantly.

• It has remained stable.
