Which is considered as the most complex species?
A microscopic, see-through water flea is the most complex creature ever studied, genomically speaking. Daphnia pulex is the first crustacean to ever have its genome sequenced, and it turns out it has about 31,000 genes — 25 percent more than we humans.
What is meant by cryptic species?
: one of two or more morphologically indistinguishable biological groups that are incapable of interbreeding — compare physiologic race.
When did the history of the species complex begin?
The development of what became known as the biological species concept began with a paper by Theodosius Dobzhansky in 1935, and was amplified by a mutualistic interaction between Dobzhansky, Alfred Emerson and Ernst Mayr after the second world war.
What is the most complex mammal?
The brains of galeomorph sharks, myliobatid rays, some teleost taxa (e.g. cichlids), corvid and psittacid birds and a number of mammals, particularly elephants, cetaceans and primates, represent the most complex ones.
What is the least complex organism?
Sci 7 – Cell specialization
A | B |
---|---|
cell | the smallest, least complex structure in an organism |
the order from simplest to most complex | cell, tissue, organ, organ system, organism |
the order from most complex to least complex | organism, organ system, organ, tissue, cell |
cell specialization | each cell is designed for a specific function |
What is a species complex in biology?
In biology, a species complex is a group of closely related organisms that are so similar in appearance that the boundaries between them are often unclear.
What is sibling species in zoology?
noun Biology. one of two or more species that closely resemble one another but whose members cannot interbreed successfully.
What is species complexity?
What are some cryptic species?
Examples of cryptic species include the African elephant. A 2001 study found the elephants were actually two genetically distinct, non-interbreeding species, the African bush elephant and the African elephant. The species are currently listed as vulnerable and threatened, respectively, by the World Conservation Union.
What is a biological species?
A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.
