That photo is from somewhere in Asia, and clearly involves some forced perspective.Well non native species do well with really no other predators to deal with.
This was supposedly caught in Hawaii
But the background trees don’t look right.
First of all note that I said "I suspect" - I am not an expert, nor do I have anything more than a hunch, so please bear that in mind with what followsWhat is it that leads you to suspect that scolopendra is originally from Asia?
Next time I’m in Hawaii I’m going to spend some time looking for various speciesI couldn't find my pictures, it must be on my old drive. But I can assure you there are other scolopendra species here. Next time i go hunting I'll try to find one. As I said they are much less common.
Diversification can occur far from the original source as animals (or plants) adapt to selective pressures in new environments. For example - look at what happened to finches in the Galapagos Islands. Not their point of origin, but diversified to meet new challenges.The first reason I suspect SE Asia is the original home of the genus Scolopendra is down variety of species and subspecies found there compared to other tropical regions......
Yes, you're absolutely right, DNA analysis can provide us with a much clearer picture than any other means.Diversification can occur far from the original source as animals (or plants) adapt to selective pressures in new environments. For example - look at what happened to finches in the Galapagos Islands. Not their point of origin, but diversified to meet new challenges.
A much better way to establish point of origin would be through phylogenetics. In DNA analysis of existing species in any group cladistics can show which species or species groups are more basal and which are more recently evolved. What you want to find is which are the more basal groups (the stock from which other groups split off in the evolutionary process)and where they may have come from. If all the more basal groups are from one region, there's a much greater chance that region is where the "original home" was. But keep in mind that centipedes are of ancient lineage - they came into being long before the continents that we recognize today did. In other words, they existed before Asia and North America did. Their "original home" was on a continent, supercontinent or land mass that has broken up, drifted and changed. The best you can hope for in finding the "original home" is to identify a region that "has become "part of the modern continent of ...." or "area that is now included in portions of the continents ......".
Some groups of centipedes that we are familiar with today (Scutigeromorpha) go back in the fossil record 416 million years. Scolopendromorpha back to the upper Carboniferous (310 to 280 million years ago). Continents have moved and changed since then. One article you may enjoy touches on some of this: http://ambre.jaune.free.fr/Chilopoda_The_fossil_history.pdfAs for centipedes being around before the continents split, of course, at least in some recognisable form. What I'm not sure about is where sections of the phylogenetic tree, such as genus Scolopendra or Ethmostigmus, stretch that far back in time or if they are more recent. I simply do not know. The reason I suspect Scolopendra is more recent is because of its poor representation in Africa and Australia, and the fact that it is plausible that the African Scolopendra branched out from Scolopendra cingulata, which in turn could only have colonised the Mediterranean with its myriad permutations after the last ice age. But yes, until we get DNA analysis this is pure speculation.
Well ya she was pissed...lol
Thanks for that. I love reading articles like these.Some groups of centipedes that we are familiar with today (Scutigeromorpha) go back in the fossil record 416 million years.
