The word evolution has a number of definitions of course - something unfortunately common in English which can lead to confusion. This can be made worse when discussing science when terms are used and it is assumed that other scientists understand the meaning due to the context. Two different meanings are
a) Biology change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift.
b) any process of formation or growth; development
The scientific theories/hypotheses regarding the origins of live and the changes in existing life forms are separate, but of course the more is learnt about one part of the overall evolution from non-living matter through to the vast number of different species we now see the more this gives indications about the other - hence the phrase 'Many lines of evidence help illuminate the origin of life'. The links provided do discuss this so hopefully were read rather than just picked due to the headlines. When discussing the science it is important to be clear and accurate as to whether we are discussing the origins of life, Abiogenesis, or changes which take place in existing life forms.The latter is normally what is meant when referring to Evolution. Perhaps biological evolution would be a better term.
There is no generally accepted model of the process that could lead to the emergence of life - as is said in one of the links - whereas the theory covering biological evolution, and speciation, are robust and very well supported by evidence. The lack of an accepted model for abiogenesis does not cast doubt on biological evolution and attempting to use this as an argument is a common ploy. Hence the need to be clear and accurate when using the word evolution.
