A colony of aliens reaches planet Earth in 3000 BC and set up a base in Antarctica. If their initial population is 100 and their specific growth rate is 0.02263/year and their yield coefficient is 0.85, then in what year (AD) will they start to outcompete humans for resources neglecting resource and logistic growth limiting effects? Assume the human population 3000 BC is 50 million, the human yield coefficient is 0.75 and the human specific growth rate is 0.02/year.
