Document Summary
Examples of dispersal include all of the following except: birds flying to islands, elephants walking over mountain ranges, mice living on an island that was once a peninsula, seeds carried by water to the shores of distant places. Rmbr when orgination is greater than extinction ( = orgination) ( = extinctions: = 0. What do the data in figure b suggest about the tempo of evolution of the. Metrarabdotos lineage of bryozoans: anagenesis, punctuated equilibrium, punctuated equilibrium and anagenesis, the tempo of evolution cannot be deduced from the figure. Coevolution: reciprocal evolutionary change between interacting species, driven by natural selection. Coevolutionary catergories: mutualsim: a positive/positive relationship between species that raises each other"s fitness, commensalism: a positive/neutral relationship that benefits one species but has a neutral effect on the other. Key concepts: each species in a coevolutionary relationshop exerts selection pressure on the others, thereby influencing their evolution.
