phylogeny Flashcards
how do courtship behavipurs help animals attract mates?
through displays and signals that are species specific.
what are the benefits of courtship behaviour?
enables recognition of same species, leading to successful mating, production of fertile offspring and raising of offspring
prevents wasteful interspecies breeding
maximised chances of sucsessfull reproduction
what is phylogenic classificaion based on?
evolutionary relationships between organisms and their ancestors
what are the advantages of phylogenic classifiction?
no overlap between groups produced
it produces a continous tree that doesn’t force organisms into taxonomic groups where they don’t quite fit
what did early classification rely on?
Visible features
what does modern taxonomy use to determine phylogeny?
molecular comparisons
developmental studies
anatomical examinations
behavioural analyses
