Convergent Evolution

28.5K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Gene Duplication and Divergence

6.3K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Anatomy of the Eyeball01:20

Anatomy of the Eyeball

7.4K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

1.7K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Area of Science:

  • Developmental Biology
  • Computational Biology
  • Evolutionary Biology

Background:

  • Vision is a crucial sensory modality for animal interaction with the environment.
  • Despite diverse eye types, genetic networks for visual system development are conserved across species.
  • Understanding how conserved programs generate diverse eye structures is a key question.

Purpose of the Study:

  • To investigate how common developmental programs are modified to produce functionally different eye types.
  • To develop a computational model simulating eye development based on known principles.
  • To explore the genetic and developmental basis of arthropod visual system diversity.

Main Methods:

  • Developed EyeVolve, an open-source Python-based computational model.
  • Modeled eye development based on principles from Drosophila melanogaster.
  • Simulated key developmental processes: tissue expansion, neurogenesis, and pigment cell formation.

Main Results:

  • The EyeVolve model successfully simulated the transition from progenitor cells to organized photoreceptor clusters.
  • Modifying five key parameters predicted diverse visual system layouts, mimicking arthropod eye variations.
  • Demonstrated that minor developmental parameter changes can explain significant evolutionary diversity.

Conclusions:

  • Conserved underlying mechanisms can explain much of the diversity in arthropod visual systems.
  • EyeVolve provides insights into common principles of eye development.
  • The model offers a new system for generating testable predictions about visual system evolution.
