'Most mammals and many birds' are mentioned to have what level of parental care?

'Nest building, egg guarding, feeding, and teaching' are activities associated with which of the following?

'The diversity of reproductive strategies among vertebrates is a key aspect of their evolutionary success.' This statement highlights the importance of what?
