You can call me Mono - it's a pleasure to meet you. Here you'll find updates from a Master of Science (Zoology) student at Melbourne University, Australia. This is a mismatch of a place; expect updates from within Uni and from out of it. I post about both zoology and its domestic cousin, animal science, and mix photos and pictures with lengthy discussions.
We know the ladies prefer bright colours, but do we know why?
Recent research may be beginning to solve the unanswered question: females birds select mates from a variety of visual cues, but why exactly do they do it?
Previous theories include that brighter colours and better songs indicate better health, or better quality. But this recent study suggests that rather than indicated superior genes, these visual cues may indicate males with a shared mitochondrial background.
And if a male’s genes are compatible with a female’s mitochondrial DNA, their offspring will be healthier.
And how have these cues evolved? It’s likely that they are related to energy production and energy efficiency.
