Genetic alteration, tissue culture, and molecular breeding are researched. Increasing food security and crop resistance to pests, diseases, and environmental challenges are vital priorities. Scientists use CRISPR and other gene-editing techniques to make drought-tolerant and nutritionally rich crops. Another promising avenue is transgenic plant-based medicines. Plant biotechnology must examine GMOs’ effects on biodiversity, ecosystems, public perception, and regulation.

11. Evolutionary Biology

Evolutionary biology looks at how different kinds of life came to be and how they have changed over time.


Natural selection, speciation, and phylogenetics. Field research, fossil records, and genetic analyses are used to study evolution and Earth’s past. Scientists study how genetic variety emerges and is maintained in populations, how sexual selection shapes features, and how speciation occurs. Comparative genomics and molecular phylogenetics enable evolutionary reconstruction and discovery of conserved genes and pathways. Evolutionary biology illuminates antibiotic resistance and novel diseases.
