|
The ancestors of each species looked very different.

Detailed explanation-1: -So, the correct answer is ‘The more their DNA sequences will match’
Detailed explanation-2: -So, the correct answer is ‘The more their DNA sequences will match’
Detailed explanation-3: -If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
Detailed explanation-4: -In contrast, shared metabolism, DNA sequences, and genetic code are all indicators that two species (or all species, in the case of the genetic code) share an evolutionary common ancestor.
Detailed explanation-5: -When two organisms share a common ancestor, their genetic code has to be similar. The extent of similarities determines how recently have the organisms evolved.
