Very excited for Henry to present this SUPER COOL work!!!! 🥳🥳🥳🥳🥳
Emocionado por compartir, en español, un poco de mi investigación con @jenncoughlan.bsky.social sobre las bases genéticas de la coexistencia de dos plantas con poco aislamiento reproductivo en el marco del día de la niña y la mujer en la ciencia y el día de Darwin en Colombia. Nos vemos el jueves :)
Desde #COLEVOL conmemoramos el día internacional de las niñas y las mujeres en la ciencia y el día de Darwin con un espacio para conversar sobre evolución, diversidad, y colecciones. Nos vemos el 12 de febrero a las 5pm en tinyurl.com/2vp2k9wp.

How does population density affect evolutionary trajectory?
Microbes construct their own niche which in turn reshapes their evolution.
