Fossil leaves from Nagaland reveal how Antarctica shaped Indian monsoons
Updated : 5 months, 1 week ago IST
A new study has established a connection between the formation of Antarctica around 34 million years ago and the early evolution of the Indian monsoon system that allowed lush forests to flourish across the subcontinent, said a statement from the Ministry of Science & Technology.

Climate Change: Lessons from latest global warming
Updated : 3 years ago IST
The Paleocene-Eocene Thermal Maximum (PETM), which resembles current and future warming, occurred 56 million years ago and was one of the largest and fastest global warming events in Earth's history. Global temperatures increased by 5-8°C during this phase.

Updated : 3 years, 1 month ago IST
Around 100 million years ago, a group of land-dwelling turtles took to the oceans, eventually evolving into the sea turtles that we know today. However, the genetic foundations that have enabled them to thrive in oceans throughout the world have remained largely unknown.

Scientists study 155 new genes to see how humans continue to evolve
Updated : 2 years, 4 months ago IST
Nearly 7 million years ago, modern humans diverged from our chimpanzee ancestors, yet we have since continued to evolve. Within the human lineage, 155 novel genes that spontaneously developed from little fragments of our DNA have been discovered. A handful of these "microgenes" are projected

Study finds how humans continue to evolve with new genes
Updated : 3 years, 2 months ago IST
Even though we diverged from our chimpanzee ancestors about 7 million years ago, we are still evolving today. The human lineage has 155 novel genes that spontaneously developed from little fragments of our DNA. Some of these novel "microgenes" are thought to be linked to diseases that are un

Changes in Earth's orbit may have triggered ancient warming event
Updated : 3 years, 2 months ago IST
Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago that is considered an analogue for modern climate change, according to an international team of scientists.

Fossil site reveals giant arthropods dominated seas 470 million years ago
Updated : 3 years, 3 months ago IST
Discoveries at a major new fossil site in Morocco suggest giant arthropods - relatives of modern creatures including shrimps, insects and spiders - dominated the seas 470 million years ago. Early evidence from the site at Taichoute, once undersea but now a desert, records numerous large "fre
