A question I've raised on Twitter I shall raise here as well--Australia has giant crocodiles, the most venomous snakes on Earth, spiders that can kill you, and even giant stinging trees. Why is evolution so nasty in Australia?

- its not so much nature thats nasty, its your perspective of things....
Look at it from a naturaul selective point of view,,,,,your 4 year old survives the giant crocs, spiders, snakes etc.... it improves our bloodstock.. the 4 year old... well.....
thats why Aussies are tough... we are a product of our enviroment.

- That's rubbish. The attrition rate from venomous animals and other unique environmental factors simply isn't high enough and Australia hasn't been heavily populated for long enough for natural selection to have an effect at the level of the population, or even local populations for that matter.Oct 2, 2011
- @ Tony, interesting.... my people been here a bit longer than a couple of hundred years.
So I will disagree with you on it having an effect on "the local population" , the local population has been here and learnt to live with our enviroment. 60,000 years long or so they say.
My original post was tounge in cheek. yes we have some nasty animals, but, if you are aware of your sourroundings and not stupid....you have to be very very unlucky to be hurt by our wildlife.
Yes they can be dangerous, but mostly its the people not the animals that put themselves in danger.
I stand by the argument that we are a product of our enviroment.Oct 2, 2011
- Its all a ploy to turn people off - we want to keep paradise clean ;). And in over 20 years, with snakes and spiders on my doorstep and sharks in the ocean I swan - I never got attacked by anything!Oct 12, 2011
- quite simply, australia has seen millions of years of long droughts which means that competition for calories is even steeper than other continents, so many predators developed strategies to ensure that prey can not get away as every meal is precious. even marsupial reproductive strategies are perfectly tuned for surviving long droughts...Nov 15, 2011
- A good evolutionary reason for developing powerful venom is to ensure a kill where food is rare. Another reason is survival. The two work together. A snake or spider that can deliver a big enough dose of a powerful venom to kill quickly has a better chance of surviving a rare encounter with a food animal that may well have good defences, and it also stands a better chance of having access to a large meal. It's no use injecting poison if the victim will wander out of range before it dies.Nov 17, 2011
