Incorrect. Species are designated by scientific names... Canis lupus is the same no matter if it lives in North America or Europe or Asia.
Of course I wasn't talking about non-scientific names. The problem is diferent scientific names being given in diferent countries.
For example: Genipa americana, exists also as: Genipa caruto, Genipa oblongifolia and Genipa excelsa. At first, they were took as four diferent species until taxonomists came to the conclusion that the four names were synonims and designated the same specie. This is a huge problem that taxonomy is still fixing nowadays.
Actually, genetics is showing that more often then not it's the opposite. You have two species that look amazingly similar but are distinct species from one another.
That's also true. But has nothing to do with what I have said. A specie can have a notable amount of anatomic variations that can lead to believe those variations are diferent species rather than only one, specialy in plants. It is thanks to genetic and molecular techniques that now biologists are discovering that there's much less species known than we thought.
Your source doesn't support your claim.
Your source still puts the total estimated number of species at over 5 million. Not counting bacteria.
You seem to have confused the estimated number of species being reduced by as much as half with the number of documented species.... which is currently over 1 million.
I wasn't talking about the estimated number of species, but the species known, which isn't 1 million, but around half million. Also, I know my source doesn't support my claim, but still sais that there is much less species in the world than we thought.
I am a biologist, this is something they teach in the career since a couple of years. The 1,500,000 quantity is obsolote, however I'm still trying to find an internet source.
