Studying Adaptation. Evolutionary Analysis of Form and Function Ch. 9. Analysis of Adaptation. A trait, or integrated suite of traits, that increases the fitness of its possessor is called an adaptation and is said to be adaptive How do we know that a trait is adaptive?
Evolutionary Analysis of Form and Function
Okapi – the giraffe’s closest living relative hypothesis(is this what ancestral giraffes looked like?)(do Okapi males fight with their necks and heads?)
If the common ancestor of taxa A-C had small testis size and small group size, then these three taxa represent only one evolutionary acquisition of small testis size and small group size. Likewise if the common ancestor of taxa D-F had large testis size and large group size
Blankaart has many fish; Driehoekvijver has few fish; Citadelpark has no fish
