Question: Historically, migration has been recorded as much as 3,000 years ago by Ancient Greek authors including Homer and Aristotle, and in the Book of Job, for species such as storks, turtle doves, and swallows. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and scientific studies have used techniques including bird ringing and satellite tracking. Threats to migratory birds have grown with habitat destruction especially of stopover and wintering sites, as well as structures such as power lines and wind farms.
Is there an answer to this question: Which species of birds were recorded 3,000 years ago?

Answer: storks, turtle doves, and swallows


Question: The act of predation can be broken down into a maximum of four stages: Detection of prey, attack, capture and finally consumption. The relationship between predator and prey is one that is typically beneficial to the predator, and detrimental to the prey species. Sometimes, however, predation has indirect benefits to the prey species, though the individuals preyed upon themselves do not benefit. This means that, at each applicable stage, predator and prey species are in an evolutionary arms race to maximize their respective abilities to obtain food or avoid being eaten. This interaction has resulted in a vast array of adaptations in both groups.
Is there an answer to this question: At most there are how many step of predator-prey interaction? 

Answer: maximum of four stages

Question: After the war, Nasser returned to his role as an instructor at the Royal Military Academy. He sent emissaries to forge an alliance with the Muslim Brotherhood in October 1948, but soon concluded that the religious agenda of the Brotherhood was not compatible with his nationalism.
