I want to know the answer to the following question:
In which period did North and South america join?
All the background I'm provided with is that "South and North America remained separated by equatorial seas (they joined during the Neogene); the components of the former southern supercontinent Gondwana continued to split apart, with Africa, South America, Antarctica and Australia pulling away from each other.". Is that enough to answer the question?
Answer: yes
