Detailed explanation-1: -Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species’ relatedness.
Detailed explanation-2: -Answer and Explanation: Of the given statements, the most accurate is that evolution by natural selection requires a genetically diverse population to be put through some kind of environmental pressure and selection.
Detailed explanation-3: -The punctuated equilibrium model (top) consists of morphological stability followed by rare bursts of evolutionary change via rapid cladogenesis – vertical equilibrium states separated by horizontal “jump” phases.
Detailed explanation-4: -Which statement is best supported by the theory of evolution? Populations that have advantageous characteristics will increase in number.
