What animals were brought by the first humans and caused the extinction of many flightless birds as well the giant egg?

The first humans brought several animals with them, notably rats, pigs, and dogs, which contributed to the extinction of many Flightless Birds, particularly on islands. These introduced species preyed on bird eggs and young birds, disrupting their populations. Additionally, the hunting pressures from humans themselves led to the decline of large flightless birds and other fauna, including giant eggs, found in places like New Zealand and Madagascar. This combination of predation and human activity drastically altered these ecosystems.
