What are some unanswered questions about evolution?

Answer 1

It is very compelling to wonder about the questions that we are not yet even capable of asking, because we are too ignorant, or because we are not yet in the 'right' world view or scientific paradigm. I think we are in no danger of ever running out of questions, and we are in no danger of running short of stunning surprises as the future unfolds.

Answer 2

The exact development of some structures is still not clear; for example, the human eye (an oft-quoted one sometimes used as 'proof' against evolution). We do have some ideas, but nothing compelling as yet - it is unlikely we will ever know for sure, since the soft tissues don't often last long enough.

Answer 3

Some could be:

1. Origin of the first cells - where did the first cell come from that could evolve into what we are today?

2. What caused the Cambrian Explosion?
By what processes did the first molecular replicators originate from which cellular life emerged - Technically this question is not a part of evolutionary research, but it is related, and fascinating.

Two questions are:

1. How could variant precursors of the current genetic code evolve and compete in a population. The current genetic code is not perfect, but to a certain degree optimized for error-correction. That means that it must have evolved. However, any change in the code itself, in the way RNA/DNA is read, immediately would render much of the genes in the genome unreadable. Therefore: by what mechanism did the current genetic code evolve from its precursors.

2. How did sexual reproduction evolve. What is the mechanism by which there came to be male and female expressions of the same genome. There are various hypotheses explaining how this might occur, but much is still unknown.
How did it start or where will it lead are two.

Answer 1

The tree of life is being built as we speak. The hypothetical phylogeny of all life on Earth from its Precambrian common ancestor (LUCA) is being constructed as we speak. Every year it seems, more and more phylogenies of the small branches of the tree of life come into focus. The questions of evolution regarding this phylogeny would include:

• How are the domains, kingdoms and phyla related to one another? And within the kingdoms and phyla, how are the classes and orders related to one another.

• Never mind the whole scope of life, we can zoom deep into the living animals and plants and bacteria themselves and ask why and how such organs as eyes, leaves, stems, wings, penises, roots, stomachs, brains and the like evolved.

• Let us zoom in again to evolution on the molecular and speciatory level. What is more common - allopatric speciation or sympatric speciation? And, even at the ancient world of protocells in the Precambrian - in what order in the molecular machinery of life evolve? In other words, what was made use of first - sugars, polynucleotides, amino acids, lipids - in the protocellular world 3.8 billion years ago?

• Never mind the zoomed picture of scurrying and flailing life, we can ask how did life disperse across deep time. And how does that explain the biogeography of life on Earth today? How did cats disperse for example? The jaguar and many small cats are featured in South America. Meanwhile, cats are spread throughout Africa, Asia and Indonesia as well. From there common ancestor, how did they move from continent to continent. The same applies to all other groups - how do they disperse between the landmasses? Actually, we might already know how the cats dispersed. I didn't look it up yet. But that gives me the opportunity for a final point. No matter how much we know, there is always more to know. How did the komodo dragon end up on Komodo? How did chameleons disperse to Africa? What is the coelacanth doing in South African waters while its closest relative (the Indonesian coelacanth) is only found in Indonesia?

Well, enough questions as examples. You get the point. There are always more questions. There are far more than two unanswered questions about evolution. Use your imagination.

Answer 5

Some unanswered questions about evolution include the exact mechanisms that drove the initial emergence of life, the role of epigenetics in evolution, and how evolutionary processes interact with cultural and technological developments in humans. Additionally, the way in which environmental changes might influence future evolutionary paths remains a topic of ongoing research and debate.

Answer 6

Who started thinking about it, did he or she realize anything similar about it.

Answer 7

Biology is the meaning of all things hellish

Answer 8
