In Greece, lions first appeared around 6,500–6,000 years ago as indicated by a front leg bone found in Philippi. [2] Bone fragments of the modern lion were excavated in Hungary and in Ukraine's Black Sea region, which are estimated at around 5,500 to 3,000 years old. [31] Remains were also found in Romania and European Turkey. [18]

The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
