This topic is debated but here is the most likely cause:
Those organisms reproduced and created more organisms. Over time the organisms changed (due to the Earth changing).
The organisms reproduced with other organisms and created a new species. After millions of years, creatures like wolves and humans now exist. Hope I helped
