comment Latency in our senses
@AliceD I agree that it's broad, but at the same time I can imagine that the poster would be quite satisfied with a table containing types of stimulus (touch at different areas, audio, visual etc), with lag times to brain activation and subjective perception for each type of stimulus. So a useful answer that could form the basis for more focused questions wouldn't have to be that long.

comment Hopeful Monsters in Plants?
@RoSiv A starting point for the relationship macroevolution and microevolution (or simply just evolution) can be found in my previous comment. I hadn't heard about "Hopeful monsters" before, so I cannot really say anything about that. Polyploidization is a full genome duplication (polyploidy is just the state of having more than two homologous chromosomes), a common cause of speciation in plants and a good example of a single event that can have large evolutionary consequences.

For answers, also see the duplicate what is the mechanism behind plants losing their leaves?.

Great! +1 Do you know where/when the picture was taken? Seems to have a high density of Nobel laureates.

comment Before Evolution was proposed by Charles Darwin, what were the leading secular theories to explain how life developed?
@AliceD I think the close reason is somewhat valid. You could write a book on this topic. On the other hand, a couple of answers that highlight different theories could probably provide a nice overview for somebody new to evolution.

comment Who are these biologists?
While not being an ideal question (where and when was the photo taken? why do you want to know?), I still think these kinds of questions should be allowed here. We have the history tag, which is relevant for this Q (history of biology), the Q has a definite answer, and BioSE should be as good a place as any to ask about the identification of prominent biologists.

comment Hopeful Monsters in Plants?
@RoSiv Macroevolution is mostly a label describing a level of studying evolution (macroevolution ~= evolution above the species level), and not a type of evolutionary change. Most evolutionary biologists would find it rather meaningless to talk about macroevolutionary changes "happening" to a species. Macroevolution is the accumulated result of many small evolutionary changes (i.e. microevolutionary changes). So in that sense, macroevolution is caused by microevolution. Sure, some single mutations can have larger effects than others, but this is not macroevolution.

What do you mean with a species having "macroevolutions" that are "prompted by smaller gradual microevolutions"? This doesn't make any sense to me.
