Protect This Earth's Species

 News Piece          
            Poachers are slaughtering hundreds of African elephants every year to get their hands on black market ivory, and illegal raw ivory trade has been taking place right under the Zimbabwean government’s nose - until now. By enforcing an international agreement, the Convention in International Trade in Endangered Species (CITES), Zimbabwe has revoked the right of export licenses.

            According to the African Elephant Database of the IUCN/SSC (International Union for the Conservation of Nature/Species Survival Commission) African Elephant Specialist Group, the elephant count in Zimbabwe totals to about 100,000, the third largest elephant population in Africa.  Since the ban by CITES in 1990, Zimbabwe is one of the few countries allowed to participate in controlled ivory trade. In the mid-1990’s, the growing elephant population became a justification for governmental authorities and environmentalists to continue the ivory trade in order to improve the living standards of the poor.
            The head of US delegation, Todd Willens, told BBC News, "939 active poaching camps were observed in a north-eastern state in Zimbabwe, representing a six-fold increase in poaching activity since 2001.” Despite this, nothing was done by the US or any other delegation.  Zimbabwe believes that the tourist trade is the best tactic for regulating and protecting the elephant herds. Whether tourism has unintentionally encouraged poaching is a still a topic of debate, as CITES has a difficult time collecting truthful facts from various government agencies.
            Before the government adopted its new restrictions, along with CITES enforcement, they issued Short Export Permits which allowed for the controlled export of worked ivory out of Zimbabwe.  The holder was required to receive the endorsement of a customs officer. When the African elephant was transferred to Appendix II of the Convention’s list of over-exploited species in 1997, this led to the authorization of the trade of ivory carvings solely for non-commercial purposes. However, the Short Export Permit did not cover the trade of raw ivory. Recently government investigation has shown that the system has been abused, and raw ivory was being disguised as souvenirs.
The Zimbabwe Parks and Wildlife Management Authority immediately took action and set new restrictions in order to further protect Zimbabwe’s elephants. The Management Authority director general Mr Vitalis Chadenga said to allafrica.com, “Zimbabwe believes in sustainable and legal wildlife trade, but we will not tolerate unscrupulous individuals who abuse the system. We are committed to curtailing any illegal trade in ivory from our country and request the co-operation of the global community to help us achieve that objective.” Now anyone wanting to carry out ivory carvings from the country is required to apply through one of the three Zimbabwean CITES management authority offices located in Harare, Bulawayo and Victoria Falls where they can obtain a CITES export permit.

            An international, wildlife trade monitoring network, TRAFFIC, oversees the trade in wildlife plants and animals to help protect the destruction of the planet’s flora and fauna. Tom Milken, the regional director of the program in eastern and southern Africa told allafrica.com, “TRAFFIC applauds the Zimbabwe government for this positive development. It's the right thing to do and sends a clear message against illegal trade practices.”

The Beauty of Evolution. Is it over?

It's clear here where evolution went wrong. But it's an evolution that took place nonetheless. But the bigger picture here is Darwin's phenomenon. Deriving from ideas of Lamarck and Malthus, the "struggle for existence" where favorable variations would prevail seem not so favorable today. Anyways, let's not forget Mendel and his inheritable genes -though all these great minds together brought us today the theory that makes this Earth go round, and our science textbooks. The change in time in one or more inherited traits. Now I am not sure if apes used computers, but I'll accept our 98% common DNA.

Now evolution isn't a simple theory, and as it isn't simple, it comes with a lot of complicated assets: variation, mutation, sex and recombination, gene flow. So what do you really need to know (that is if you haven't learned about this enough through out your years in school and are NOT a science student)?
Let's look at the timeline so you can see just how young and naive we are:



  • 4,600,000,000 years ago: the Earth forms and is bombarded by meteorites and comets.
  • 3,800,000,000 years ago: the precursors of DNA form. 
  • 3,500,000,000 years ago: unicellular life evolves.
  • 555,000,000 years ago: Multi-cellular marine organisms.
  • 500,000,000 years ago: fish-life vertebrate form, and invertebrate.
  • 450,000,000 years ago: Arthropods move onto land, forming spiders, scorpions, mites and millipedes. 
  • 420,000,000 years ago: land plants evolve drastically changing the Earth's landscapes and forming new habitats.
  • 360,000,000 years ago: Four-limbed vertebrates move onto land as habitats and forests grow; reef systems.
  • 250,000,000 years ago: Pangea forms.
  • 248,000,000 years ago: Over 90% of Earth's marine life and 70% of Earth's terrestrial life goes extinct during the Earth's largest mass extinction.
  • 225,000,000 years ago: Dinosaurs and mammals evolve. Pangea begins to break apart.
  • 130,000,000 years ago: Earliest flowers evolve as the continents form. Dinosaurs dominate; bony fish diversify. 
  • 65,000,000 years ago: Dinosaurs go extinct. (massive asteroid - of course this is debated like everything else)
  • 4,000,000 years ago: Early hominid "Lucy" lives, the ice age begins and many large mammals go extinct. 
  • 130,000 years ago: Anatomically modern humans evolve. Seventy thousand years later their descendants create cave-paintings and show the first sign of consciousnesses.

So after this long the question now remains, is human evolution finally over?

Has our species reached its biological pinnacle? Some believe that this is our present-day Utopia, that it won't get much better than this. Others believe that mankind is still being influenced by the evolutionary forces that created this pyramid of species that inhabited the planet more than 3 million years ago. Some see growing neurotic geniuses, some see a dumbfound standstill.
How will you evolve?
