Hi, I just wanted to know If we did measure and observe this things in evolution:

1) Loss of information in the genes such as devolving traits.

2) Gain of information in the genes such a developing new traits. (Could be the Lenski Experiment be an example of this?)

3) All the mentioned above was observed at a macro scale such as fossils, genes, embryology, etc?

1) Plenty of species went exinct in the last few centuries, i 'm not sure how many of their genes still survive in other species.

There is probably more, but i 'm not aware whether we actually tested for this.

 

2)Plenty of new (arrangement of) genes, which get interpreted differently.

 

3) It is easier to see on a macro-scale, but for scientific testing you need multiple generations, so mostly smaller creatures(bacteria etc.) have been experimented with.
