Detailed explanation-1: -In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities.

Detailed explanation-2: -In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

Detailed explanation-3: -The Galpagos tortoises share a common ancestor, but have necks of different lengths to best reach the food they need in their environment. This kind of evolution is proven by DNA analysis and results in organisms with different ancestors becoming more alike as they adapt to similar environments.

Detailed explanation-4: -Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures.

Detailed explanation-5: -Homologous features 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.
