Describe the embryological support for evolution.

(N/A) Embryological support for evolution was proposed by $Ernst$ $Haeckel$ based on the observation of certain features during the embryonic stage that are common to all vertebrates but absent in adults.
For example,the embryos of all vertebrates,including humans,develop a row of vestigial gill slits just behind the head. However,these are functional organs only in fish and are not found in any other adult vertebrates.
$\rightarrow$ This proposal was later disapproved after a careful study performed by $Karl$ $Ernst$ $von$ $Baer$.
$\rightarrow$ He noted that embryos never pass through the adult stages of other animals; rather,they share common embryonic characteristics that reflect their evolutionary ancestry.
