Final answer:
The baby mammoth Lyuba, discovered in 2007, was the first of the frozen mammoth calves to be unearthed in Siberia. Lyuba's well-preserved state offers valuable information about the ecology and extinction of woolly mammoths. The discovery complements the knowledge obtained from other specimens, including the mummified remains of a mammoth calf called Effie in Alaska.
Step-by-step explanation:
The Lyuba was the first of the frozen mammoth calves to be unearthed in Siberia. Discovered in 2007, Lyuba was a one-month-old baby mammoth whose remarkably well-preserved state has provided significant insight into the life and environment of woolly mammoths. Woolly mammoths are an extinct species that began to disappear around 10,000 years ago; however some populations survived in isolated regions like Wrangel Island until approximately 1700 BC.
The information gleaned from frozen specimens like Lyuba helps us understand the ecology and extinction of these ancient creatures. Other notable finds of woolly mammoths include the discovery of a mummified mammoth calf nicknamed Effie in Alaska by a gold mining operation. While Effie still retained tissue and hair it was not the first frozen calf to be discovered. Content loaded from these finds contributes significantly to our understanding of prehistoric life and the preservation of organic material in extreme conditions.
