im in awe…
found these pics on someone’s blog….
thats the reason why thee nature-photography based blogs are toplisted!
check this out…. apparently, its a “one-in-a-zillion” kind of genetic mutation, which causes the penguin to appear all black!
mutations may be one of the main reasons why species evolved so diversely. creating new species, with new habitats and niches. new characteristics, new defense methods, new predators and new preys.
so, while scientists have found this rare mutation, causing a penguin to be fully black, we have to wait and see how this mutation works out for the flightless bird. whether its a boon or a bane……. whether it’ll survive better, or whether the mutation causes its demise sooner than others…
a number of you may have already heard that a new human species may have been discovered…
this one, if confirmed as a new species, will mean that there are 3 species of humans that once/are walking the face of earth. Homo neandethalensis, Homo sapiens and now X-woman.
scientists discovered a fossilized child’s last finger in some cave in russia. so, naturally they sequenced it. the immediate sequencing was done using mitochondrial DNA, since there’s an ‘abundance’ of in in the fossil. although mitochondrial DNA contains very little information abt the child’s genotype and phenotype, scientists still found that the mitochondrial genetic sequence is very much different from Homo neanderthanlensis and Homo sapiens.
so the next thing that scientists are doing is to carefully extract nuclear DNA from the last finger and to duplicate it to a quantity thats sufficient to conduct various sequencing and genetic screening.
its interesting to think that while only one species of hominids exist for the past few thousands of yrs, there may have been different species of hominids living a million yrs ago. the fossilised child’s little finger dates back to approximately 50000 yrs ago.. thats, not that far back on the evolutionary scale.
afterall, there is evidence that our ancestors, neanderthals wear decorative jewelry and made tools which suggest that they had higher knowledge. maybe Homo sapiens had some significant advantage over the ancestors…. something always has a significant advantage over another species. thats why i say, the end of the world, isnt as dead as it sounds to be..
the other human species which scientists are still disputing over whether or not to categorise as a true species, has been scientifically named Homo florensiensis. though scientifically named, (which means it has a genus and a species name), many scientists are still in disagreement of this. to laymen, this might be know as the hobbit, discovered in indonesia a few yrs back.
what would life have been like if we weren’t the only human species around? would the other hominids be kept as animals? would they have evolved as successfully as we have?
wouldn’t the term human race have an entirely different meaning?
an entirely different meaning…
since ICCS last yr, ive not been to kranji mudflats… so, going there yesterday, only to see a huge mess of garbage AGAIN was so disappointing.
i was told that it probably is the change in directions of the monsoon, that brought all the rubbish in. so, i hope ppl will realise the importance of littering into any water body, because it all leads to the sea, and the sea must end at some land. all the rubbish gathers there, and it just creates this unsightly, unhygenic, and nature-disruptive scene which is heart breaking.
coastal clean ups wont matter must if rubbish keeps coming in! argh…
we spent abt 2 hrs collecting them, and walking toe-first in the mud is causing my thigh and calf muscles to hurt like i ran for 5 hrs…
quite sad to look at. but i dont think its a result of human abuse… maybe a bird pecked on it…
high point was that instead of finding a mating pair, i found a threesome! “young HSCs these days…. sigh… no morals..” haha!
and we still havent found where they stash their eggs!
after washing up, we stood around and chatted for a while. and then we saw these bunch of ppl with a bucket of flower crabs. apparently they fish for them in the water by laying traps. and then coming back to collect the traps. and they said that it was a good day for collection.
and then they sell. or rear. or bbq them….
“is this legal” i asked someone. who replied, “its not illegal.” and “if they are catching crabs like this everyday, sooner or later, the crab population will suffer”
i was genuinely elated to know that we were going to do something to commemorate Earth Hour… though, all staff wont be in sch, since that 1 hr actually happens at night. but still, i was genuinely happy!
we planted mango saplings. each department planted one. and, i really feel we might have made a statement. we care. :)
(a group pic which i will not publicise)
hope all of you participate in Earth Hour 2010. make a difference. each one of you do. :)
there are these 2 MPs that i see almost every morning, as i wait for CL to pick me up in a cab.
they walk past me with a jacket over their uniform, but that doesnt stop the large white belt from showing.
almost every morning, i see them walk to the zebra crossing. stop for a while to check for vehicles. cross the road. stop at another traffic light and wait for the green man to appear, even though there are no moving vehicles obstructing them from jay walking.
every other NSF/regulars/MINDEF personnel takes the short cut by diagonally cutting across the zebra crossing and the other road together. except these 2 MPs. and other MPs that i have recently observed.
is it the presence of MINDEF guards that prevent the MPs from jay walking?
almost every morning, i wonder if they obey all the traffic regulations every where they go. whether its drilled into them that MPs have a ‘legal obligation’ to be lawful when they are in MP uniform. do they do it because they have a sense of pride? or because they could be court marshalled?
i know the importance of being in a uniform. the responsibility is greater when you are seen as a member of an organisation.
a policeman cannot choose not to question a wrong act, more so when he is in uniform.
a st john member cannot forestall his duty, more so when he is in uniform and sees someone who urgently needs first aid.
so what drives us? the idea of moral binding or the fear of punishment or fear or embarrassment?
being a layman is different from being recognised by a layman. certain behaviours must be established. if not for anything, at least for the fact that ppl are watching and judging everything you do, more so when you are in a position where you are recognised and associated by members of the public.
