In both of these cases, humans became entangled with these species as the relationship between them, and the human role in their survival and reproduction, intensified. [7]
The lineages of modern dogs and wolves may have split thousands of years earlier than previously thought. According to new research, the divergence happened around 27,000 to 40,000 years ago, far ...

[ 14 ] The Australian honey possums acquired a long tongue for taking nectar from flowers, a structure similar to that of butterflies , some moths, and hummingbirds, and used to accomplish the same task.
