Answer:

scientists say the gradual shrinkage of the whales' hind limbs over 15 million years was the result of slowly accumulated genetic changes that influenced the size of the limbs (they used to have legs)

please give this brainliest!!

Explanation:

Whale pelvic bones evolved to help the them maneuver better during intercourse. They have very small pelvic bones compared to their body Scientists have discovered that the tiny bones may actually play a huge role in whale reproduction.

They have the pelvic bone to help them mate. male whales need the pelvic bone because it appears necessary to attach larger muscles for penis control.

Lubov Fominskaja [6]

Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.

<h3>What are skeletal traits?</h3>
  • The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
  • Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
  • Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
  • We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).

How does convention occur in the troposphere
Zarrin [17]

Convection causes heating in troposphere because it drops in temperature with altitude, but has a relatively high density of air. The stratosphere has no weather because convection cannot happen because the air gets hotter in this layer as you go up in altitude.
