Yes, the humans are invasive species.

Explanation:

The homeland of the modern day humans is Africa, thus they are native o the African continent. But the humans started to spread gradually, first in Eurasia, and later in Australia, North America, South America, and the Pacific islands, to a point now where they have reached pretty much every corner of the world. This is a textbook example of an invasive species that has entered into new ecosystems. Not just that the humans were entering into new ecosystems, but they also were changing the ecosystems, more often then not causing a lot of damage on them, leading to the destruction of lot of habitats and extinction of lot of species.
