Today, scientists view speciation as a complex process influenced by various mechanisms, including natural selection, genetic drift, and reproductive isolation. They recognize that speciation can occur through allopatric (geographic separation), sympatric (same location but different niches), and parapatric (adjacent populations) pathways. Advances in genetics and genomics have also highlighted the role of gene flow, hybridization, and polyploidy, particularly in plants, in driving speciation. Overall, the modern understanding emphasizes that speciation is a dynamic and multifaceted process shaped by both ecological and evolutionary factors.

The study of evolution from a genetic point of view is known as evolutionary genetics. It focuses on how genetic variation within populations changes over time, leading to the evolution of new species. By studying genes and their interactions, evolutionary geneticists can uncover mechanisms driving evolution.
there is ongoing study and debate about this processes

The first scientist to view cells under a microscope was Robert Hooke, an English scientist, who observed cork cells in 1665. His observations marked the beginning of the cell theory in biology.
Instantaneous speciation, also known as saltation, is a theory in evolutionary biology that suggests new species can arise suddenly and rapidly, rather than through gradual accumulation of small changes. This idea challenges the traditional view of gradualism where species evolve slowly over time. However, there is limited empirical evidence to support the concept of instantaneous speciation.

ya,ofcourse from my view
according to my point of view sacretis is the scientist who advocates idealism.but it is not answer .pls reply me
Scientists see the world as what it is; laypeople view it according to what they believe it is.
