Answer:
No, speciation doesn’t occur in specific characteristics and predictable manner.
Explanation:
Speciation means creation of a new kind of plant or animal. When a particular species separates from its members of species and develops its own characteristics, speciation occurs.
There are different types of Speciation. In allopatric speciation, species separate due to geographical conditions like waterways or mountain range and evolve into separate species. Whereas in Sympatric speciation, species evolve into separate ones without any change in geographical conditions. Other types of speciation are artificial, peripatric and parapatric type of speciation. So, these changes are neither specific nor predictable.
Speciation occurs naturally through the inheritance of genes from ancestors. Speciation is influenced by environmental conditions such as geographical conditions.
Further explanation
Speciation is the emergence of new species from the evolutionary process.
Evolution (in biological studies) means a change in the inherited characteristics of a population of organisms from one generation to the next.
These changes are caused by a combination of three main processes:
- variation
- reproduction
- selection
These traits which form the basis of evolution are carried by genes that are inherited from the descendants of living things and vary in a population.
Evolutionary thoughts such as common ancestors and species transmutation have existed since at least the 6th century BC when this was explained in detail by a Greek philosopher, Anaximander.
Organizational evolution occurs through changes in inherited traits. Eye color in humans, for example, are these inherited traits.
The phenotype of an individual organism results from the genotype and environmental influences of that organism. Substantial phenotype variations in a population due to differences in genotype.
Variations come from:
- genetic material mutations
- migration between populations (gene flow)
- changes in the composition of genes through sexual reproduction
Genetic variation comes from random mutations that occur in the genome of an organism. Mutations are changes in the genomic cell DNA sequence and are caused by:
- radiation
- virus
- transposon
- mutagenic chemicals
- and errors during the process of meiosis or DNA replication
