Under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategy. Some organisms breed only once in their lifetime (Pacific salmon fish, bamboo) while others breed many times during their lifetime (most birds and mammals).
Some produce a large number of small-sized offspring (Oysters, pelagic fishes) while others produce a small number of large-sized offspring (birds, mammals).
Desert lizards cannot maintain a constant internal body temperature (they are ectothermic). Instead, they change their behavior to regulate temperature. Bask in the sun in the morning when it’s cold. Hide in burrows or under shade when it gets too hot.
