Hi!
The selection in this case would be natural selection.
Natural selection is a process that involves organisms with favorable characteristics having a higher chance of reproductive success, and passing on their traits onto the offspring. This process, as opposed to artificial selection, does not involve human intervention and is a natural phenomenon.
In our case, whales with maximum length (the favorable trait) are mating on accord of their own, without external factors governing the process; hence, the selection is natural.
Hope it helps!
Answer:
d. CT scans of the fossilized skulls of Hobbits suggest they were probably microcephalic modern Homo sapiens.
Explanation:
The work of Falk et al in 2007 compared the CT of microcephalic humans skulls and normal humans skulls, finding the variables that allow them to classified with 100% success. When compared with the skulls of the ‘Hobbits’ of Flores, the size is similar to the microcephalic skulls in humans but the shape features sort it with normal humans skulls. They concluded that the ‘Hobbits’ of Flores are a separate species.
The answer would be adaption or evolution in the animal kingdom
Answer: Option A ,Band C.
Explanation:
Sympatric speciation is the evolution or isolation of new species from the original populations of species occupying in the same geographical area. Sympatric speciation commonly occur due to sexual selection of mates can cause reproductive barriers or isolation which keep gene pools separate. A plant with extra set of homologous chromosomes is an example of sympatric speciation.
