Deforestation in Brazil's Amazon rainforest in 2023 halved from the previous year to its lowest level since 2018, government data showed on Friday, a major win for President Luiz Inacio Lula da Silva in his first year in office.

Lula has staked his international reputation on reducing deforestation in the South American country, with pledges to end illegal clearing by 2030. Under his predecessor Jair Bolsonaro, destruction accelerated in the world's largest rainforest.

According to preliminary satellite data from space research agency INPE, 5,153 square kilometers (1,989.6 square miles) of the Amazon were cleared in 2023, a 49.9% drop from 2022.

That is still an area more than six times the size of New York City, underscoring the challenges faced by Lula to fulfill his promise, but the lowest since 2018, the year before Bolsonaro took office.

In December alone, INPE data showed, deforestation dropped 23% year-on-year to 176.8 square kilometers.

Brazil's Environment Ministry said the positive figures came on the back of "decisive" inspection efforts by environment watchdog Ibama, stressing that the number of notices of infraction issued by the agency rose 106% in the period.

"This is the first step towards achieving the goal of zero deforestation by 2030," the ministry said in a statement on social media.

Scientists have discovered the oldest-known fossil of a giant tadpole that wriggled around over 160 million years ago.

The new fossil, found in Argentina, surpasses the previous ancient record holder by about 20 million years.

Imprinted in a slab of sandstone are parts of the tadpole's skull and backbone, along with impressions of its eyes and nerves.

“It's not only the oldest tadpole known, but also the most exquisitely preserved,” said study author Mariana Chuliver, a biologist at Buenos Aires’ Maimonides University.

Researchers know frogs were hopping around as far back as 217 million years ago. But exactly how and when they evolved to begin as tadpoles remains unclear.

This new discovery adds some clarity to that timeline. At about a half foot (16 centimeters) long, the tadpole is a younger version of an extinct giant frog.

“It's starting to help narrow the timeframe in which a frog becomes a frog,” said Ben Kligman, a paleontologist at the Smithsonian National Museum of Natural History who was not involved with the research.

The results were published Wednesday in the journal Nature.

The fossil is strikingly similar to the tadpoles of today — even containing remnants of a gill scaffold system that modern-day tadpoles use to sift food particles from water.

That means the amphibians' survival strategy has stayed tried and true for millions of years, helping them outlast several mass extinctions, Kligman said.
