Meet Lucy, a 3.2 million-year-old ancestor of ours. Though she looks like an ape, her knees were close together, just like a human’s! That positioned her feet directly under her body and made walking easier.
See the final installment of Your Inner Fish tomorrow night (4/23) on PBS at 10/9c.
If evolution is an ongoing process then why doesn’t the “Lucy” species still exist? I feel like since evolution is still occurring today there shouldn’t be any missing thinks because those species would keep being recreated through the process of evolution.
