The feature is called Evolution based on hypothesis. Charles Darwin's Hunting hypothesis was that Bipedalism freed the hands for making tools. Rodman and McHenry's patchy Forest Hypothesis, bipedalism was ore efficient than quadrupedalism such that forests diminished and food resources also became scattered. Also not valid because bipedalism evolved in a forest environment. Owen Lovejoy's Provisioning Hypothesis that males assist females more efficiently in procuring food; the need for food hypo, Birth spacing would be reduced.
Siderophores are proteins produced by bacteria, and compete with the host's iron-transport proteins. They aim to bind and "hijack" the host's cell iron molecules for their own pathogenic cell processes
