Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

2.7K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

Convergent Evolution01:54

Convergent Evolution

30.1K
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.

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

6.7K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

The Evidence for Evolution02:55

The Evidence for Evolution

45.5K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Pigmentation01:19

Pigmentation

3.6K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Reticular Dermis01:15

Reticular Dermis

3.8K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Area of Science:

  • Zoology
  • Evolutionary Biology
  • Genetics

Background:

  • Whales and hippos exhibit adaptations to aquatic and semi-aquatic lifestyles.
  • Understanding the genetic and anatomical basis of these adaptations is crucial for evolutionary studies.

Purpose of the Study:

  • To investigate the skin anatomy and genetics of whales and hippos.
  • To determine if adaptations for aquatic lifestyles evolved convergently in these species.

Main Methods:

  • Comparative analysis of skin anatomy between whales and hippos.
  • Genetic sequencing and analysis of key genes involved in skin adaptation.

Main Results:

  • Identified shared anatomical features in the skin of whales and hippos related to aquatic life.
  • Revealed convergent genetic patterns underlying these adaptations.

Conclusions:

  • The study provides evidence for convergent evolution of aquatic adaptations in whale and hippo skin.
  • These findings deepen our understanding of evolutionary processes in mammals adapting to water.
